COVID-19 is known to cause various cutaneous lesions, including acro-ischemic lesions (AIL), which are associated with poor prognosis. Anticoagulant therapy has shown positive responses in AIL patients. However, in this case study, we present a fatal AIL case despite anticoagulant therapy. We propose different treatment approaches based on the limited current data on acro-ischemia pathogenesis related to SARS-CoV-2. The clinical case involved a 59-year-old male with severe COVID-19 symptoms, including acrocyanosis and right hemiparesis. Despite receiving anticoagulant therapy, the patient's condition worsened, leading to necrosis in the left foot. The discussion focuses on the high-risk nature of AIL, the potential link between angiotensin-converting enzyme 2 (ACE2) receptors and vasculitis or thromboembolic manifestations, and the role of immune clots in AIL pathogenesis. Behçet syndrome is referenced as a model of inflammation-induced thrombosis, guiding the suggestion for immunosuppressant-based treatment in addition to anticoagulants. Additionally, three substances, N-acetyl cysteine, sulodexide, and hydroxychloroquine, are proposed.

The objective is demonstrate the diagnostic process and evolution of a patient with a diagnosis of congenital pulmonary vein stenosis and broncho-pulmonary vascular malformation. One year old female patient with repeated bronchopneumonia, acrocyanosis, split S2, cardiomegaly, pulmonary hypertension, with a clinical diagnosis of atrial septal defect. The echocardiogram demonstrated left sided vein pulmonary stenosis. The cardiac catheterization demonstrated arterial-venous fistulas apical on the right lung. Magnetic Resonance image and angiography showed an aberrant arterial vessel parallel to the abdominal aorta which flow the right pulmonary lobe. The cardiac tomography angiography reported confluence of right-sided pulmonary veins. A lobectomy is performed. Patient died in post-operative due to massive pulmonary hemorrhaging. This is the first patient mentioned in written literature with pulmonary vein stenosis associated with pulmonary sequestration, with normal venous connection. Echocardiography represents the specific standard study ideal for initial diagnostic for patients with pulmonary vein stenosis.

Dear Editor, Ticks carry many diseases, bacteria, and viruses and represent a very important healthcare issue both in Croatia and globally. Although most ticks are not infected with pathogens dangerous to humans, some ticks can transmit infectious diseases with significant morbidity and mortality. This is caused by the increasing incidence of many tick-borne diseases over a growing geographical area. Many factors influence which species of ticks are present in a given geographical area, as well as the density of their population and the risk of human exposure to infected ticks. The average morbidity from Lyme borreliosis in the Republic of Croatia is 6.51 infected per 100,000 inhabitants. There can be no Lyme borreliosis without ticks infected by Borrelia burgdorferi (1,2). In Europe, Lyme borreliosis (LB) is caused by the Borrelia burgdorferi sensu lato complex genotype. There are three skin manifestations of LB: erythema migrans (EM), borrelial lymphocytoma (BL), and acrodermatitis chronica atrophicans (ACA) (3,4). Herein we describe a female patient with a diagnosis of Lyme disease based on the non-specific clinical picture and laboratory diagnostics, in whom successful treatment led to complete regression of all skin manifestations. The patient was a 58-year-old woman with no previous history of severe illness. Notably, the patient history showed that, eight months prior to presenting for the dermatological exam, the patient had observed the appearance of edema and demarcated macular exanthema around both ankles and subsequently on the dorsum of the right hand, which spread to the left hand and with gradual spread to both lower legs and the lower extremities, with more pronounced changes on the left leg. The initial dermatological examination found pronounced skin changes on both legs, especially the left leg, with erythematous changes in the form of figurate erythema forming confluences up to the size of a smaller palm; the skin of the left leg was partially mottled with normal turgor and elasticity (Figure 1a and Figure 1b). Inguinal lymph nodes were enlarged and painless on palpation. Changes were minimal and discrete on the right leg and were absent on the torso, upper extremities, and skin. Subjectively, there was no itching, burning, or tingling sensation in the affected areas of the skin. The patient subjectively reported feeling well. Family history showed that the patient's father had died from prostate cancer and that the mother had died from melanoma. Laboratory findings were as follows: hematological, biochemical, and immunological parameters were normal. Venous and arterial ultrasound of both legs was normal, with the presence of reactively enlarged left inguinal lymph nodes. Lyme disease was suspected based on the clinical picture, with a differential diagnosis of possible livedo reticularis. A biopsy of the skin changes was also performed, with the results showing that the histological picture in the examined material could be compatible with the provisional clinical diagnosis of livedo reticularis. IgM and IgG specific for Borrelia burgdorferi was also performed: IgG was borderline, whereas IgM was positive at 218 U/mL. Over the next 3 weeks, Amoxil 500 mg thrice daily was introduced to the treatment. After completion of the treatment, there was a gradual regression of all skin changes without the appearance of new lesions (Figure 2a and Figure 2b) (Figure 3a and Figure 3b). Patient follow-up over the next year did not find any recurrence of similar skin changes. Herein we have described the case of a patient with atypical skin changes in which the presence of antibodies for Borrelia burgdorferi was demonstrated, in which regression of all skin manifestations was achieved after diagnosis and adequate antibiotic treatment. Lyme disease has a wide spectrum of clinical manifestations that can generally be observed in three stages: the early localized stage, the early disseminated stage, and the late stage of the disease. However, it is also possible for the different stages to overlap and even for the late stage to manifest without any signs and symptoms of the earlier stages. Early localized stage. Characterized by skin changes - erythema migrans (EM) - usually manifests within a month of the tick bite (usually 7-14 days after the bite) (Figure 4 and Figure 5). EM manifests in approximately 80% of patients, but only 25% of patients can recall the tick bite. The skin changes are usually localized in the axilla, the groin, the cubital area, or around the waist. The changes are generally not painful, but can itch or be warm to the touch. They gradually spread over days or weeks and can grow to a radius of up to 20 cm. Initially, the coloration can be uniform for several days, after which the redness disappears around a central zone (4-6). Multiple skin changes are a sign of spirochetemia and not the result of multiple tick bites. Due to timely antimicrobial treatment, multiple skin changes are much rarer today. In the initial days or weeks after infection, patients with early, localized, or disseminated Lyme disease often present with non-specific signs and symptoms resembling a viral infection: fatigue, headache, loss of appetite, joint pain, and regional lymphadenopathy. Fever can be present in approximately 20% of patients. Laboratory findings in this phase are non-specific. Erythrocyte sedimentation can be slightly increased, leukocyte counts are mostly normal, and anemia and thrombocytopenia are present only rarely (7,8). Early disseminated stage. This stage is marked by numerous EM lesions (that generally appear days or weeks after the infection) and/or neurological and/or cardiac manifestations (occurring weeks or months after infection). Some of these patients have no data on the presence of early localized Lyme disease. The most common triad of neurological manifestations are meningitis, neuropathy (usually of the facial nerve) and motor or sensory radiculopathy (Bannwarth syndrome). All these manifestations can appear individually. Cranial nerve neuropathies can often be bilateral. Late-stage Lyme disease. Characterized by intermittent or permanent arthritis in one joint or several large joints, most commonly the knees, and/or more rarely by neurological symptoms such as discrete encephalopathy or polyneuropathy. Late-stage Lyme disease can develop several years after primary infection, and arthritis can be the first manifestation of the disease, with the early localized and early disseminated stages not manifesting at all. In Europe, patients with late-stage Lyme disease can present with chronic skin changes (acrodermatitis chronica atrophicans), which is not observed in the USA. It is caused by B. afzelii and is typically localized to the extensor surfaces of the hands and feet. It is most common in women >40 years of age but can also present in younger populations. However, due to early antimicrobial treatment of the earlier stages of the disease, late-stage manifestations are rare (9). The discovery of the etiology of this disease showed that some well-known clinical entities were also a manifestation of Borrelia infection. The etiology of other dermatologic diseases was thus determined, such as lymphocytoma (or lymphadenosis cutis benigna), which was recognized as an entity as early as 1884, as well as acrodermatitis chronica atrophicans, described in 1888, erythema chronicum migrans (Afzelius-Lipschütz), and the neurological disease called Bannwarth syndrome, the symptoms of which were described as early as 1922 (10,11). LB and all its dermatological manifestations occur in almost all European countries, predominantly in the central part of the continent. The annual incidence is between 9.4 cases per 100,000 inhabitants in France to 120 cases per 100,000 inhabitants in northeastern Poland, 130 cases per 100,000 inhabitants in Austria, and 155 cases per 100,000 inhabitants in Slovenia (12). The total prevalence of ACA in all European patients with LB is 1-10%, depending on the region. For example, BL and ACA comprise 0.3% of LB cases in Bulgaria. In Norway, ACA comprises 5% of all clinical LB cases, and in northern Italy that number is 2.5%. Establishing a diagnosis of ACA is much more difficult than diagnosing EM or benign lymphocytoma (BL) because the clinical manifestations of ACA can vary. Acrodermatitis chronica atrophicans is probably the most common late and chronic manifestation of LB that can be observed in European patients. The skin changes in our patient were fairly non-specific, based on descriptions from the literature, but positivity for IgM antibodies was important for establishing the diagnosis, along with the very good response to antibiotics regarding regression of skin changes as well as the histological analysis that, according to the pathohistological diagnosis, indicated livedo reticularis, which is in turn also described in the literature as a possible form of ACA depending on the stage of the disease. Skin changes on the lower extremities are often incorrectly interpreted as vascular insufficiency, e.g. chronic venous insufficiency, superficial thrombophlebitis, hypostatic eczema, obliterative arterial disease, acrocyanosis, livedo reticularis, or lymphoedema, but they can also be the result of ACA, as in our case (13-15). In cases such as the one we have described, clinical manifestations of Lyme disease can very often vary and differ greatly from the typical clinical picture. This is demonstrated by our case, which also shows that LB and its idiosyncratic manifestations can lead physicians astray in a condition where failing to establish a timely diagnosis can be fatal for the patient. This case report also serves as a reminder that Lyme disease should be considered whenever atypical skin changes are encountered. Given that ACA is a disease in the late stage of Lyme disease and that the changes in our patient were noticed at the very beginning, the disease did not develop to the later stage.

A man in his 70s, with a recent diagnosis of transitional cell carcinoma of the bladder, reported a 2-month history of discolouration, pain and paraesthesia affecting his fingers. Clinical assessment noted peripheral acrocyanosis with areas of digital ulceration and gangrene. Following further work-up to evaluate potential causes, he was diagnosed with paraneoplastic acrocyanosis. He proceeded to undergo robotic cystoprostatectomy and received adjuvant chemotherapy for the management of his cancer. In parallel to the chemotherapy, vasodilatory therapy was administered as two courses of intravenous synthetic prostacyclin analogue iloprost along with sildenafil. This resulted in a significant improvement in digital pain and gangrene with healing of ulceration.

Secondary acrocyanosis after spinal cord injury is extremely rare. We describe a case with secondary acrocyanosis in a complete T12 paraplegic patient. A 41-year-old man with complete T12 paraplegia after a gunshot wound to the thoracic spine 20 years prior presented with a four-month history of bilateral foot bluish discoloration precipitated when he sat with his legs down, improving rapidly after a few minutes of leg elevation. Changes in the skin color of the lower extremities were evaluated in the seated position for two hours. The skin color became darker, progressing to a bluish discoloration through the entire length of the legs. After two hours, the feet and most of the legs appeared deep purple. The color of the legs returned to their baseline three minutes later after the patient was placed supine in the bed. The diagnosis of secondary acrocyanosis due to the T12 spinal cord injury was established based on the physical examination and ancillary tests showing no peripheral ischemia. Other causes of secondary acrocyanosis were excluded during the work-up. This report presents the first case of a paraplegic patient with spinal cord injury presenting secondary acrocyanosis.

Ethylmalonic encephalopathy (EE) is a very rare autosomal recessive metabolic disorder that primarily affects children. Less than one hundred EE patients have been diagnosed worldwide. The clinical manifestations include chronic diarrhea, petechiae, orthostatic acrocyanosis, psychomotor delay and regression, seizures, and hypotonia. The gene has been shown to be associated with EE, and genetic sequencing provides concrete evidence for diagnosis. To date, only 37 variants of have been reported as disease-causing in EE patients. We identified two novel variants, i.e., c.595+1G>T at the canonical splice site and the missense variant c.586G>C (p. D196H), in a 3-year-old Chinese boy with EE. The patient had mild symptoms with only chronic diarrhea. The typical symptoms, including spontaneous petechiae, acrocyanosis, and hypotonia, were all absent. Herein, we report on the clinical, biochemical, and genetic findings of our patient and review the phenotypes and genotypes of all patients with EE caused by variants with available information. This study supports the early assessment and diagnosis of EE.

Cold environments can trigger a variety of conditions, which, in their acute phase often present to the Emergency Department. Primary acrocyanosis is a distinct, rare condition which may be missed resulting in misdiagnosis and mismanagement. Primary acrocyanosis is a peripheral vascular disorder defined by painless, symmetrical discoloration of the distal appendages and uniquely characterized by persistence of the skin color changes after cold exposure. We present a case of a 24-year-old female who presented to the Emergency Department with peripheral cyanosis after cold exposure and was eventually diagnosed with primary acrocyanosis by Rheumatology. The prognosis for primary acrocyanosis is quite good in comparison to other acrosyndromes and once secondary causes of acrocyanosis have been ruled, out can be managed conservatively with lifestyle modifications and potential follow-up with Rheumatology.

BACKGROUND
Infrared Thermography (IRT) has been used for over 30 years in the assessment of Raynaud Phenomenon (RP) and other peripheral microvascular dysfunctions in adults but, to date, very little experience is available on its use in children for this purpose. The first aim of the study was to assess reproducibility of thermographic examination after cold exposure by comparing inter-observer agreement in thermal imaging interpretation. The secondary aim was to evaluate whether IRT is reliable to diagnose and differentiate peripheral circulation disturbances in children.
METHODS
Children with clinical diagnosis of primary Raynaud's phenomenon (PRP), secondary RP (SRP), acrocyanosis (AC) and age-matched controls underwent sequential measurements of skin temperature at distal interphalangeal (DIP) and metacarpophalangeal (MCP) joints with IRT at baseline and for 10 min after cold challenge test. Intraclass correlation coefficient (ICC) was calculated for inter-rater reliability in IRT interpretation, then temperature variations at MCP and DIP joints and the distal-dorsal difference (DDD) were analysed.
RESULTS
Fourteen PRP, 16 SRP, 14 AC and 15 controls entered the study. ICC showed excellent agreement (> 0.93) for DIPs and MCPs in 192 measures for each subject. Patients with PRP, SRP and acrocyanosis showed significantly slower recovery at MCPs (p < 0.05) and at DIPs (p < 0.001) than controls. At baseline, higher temperature at DIPs and lower at MCPs was observed in PRP compared with SRP with significantly lower DDD (p < 0.001). Differently from AC, both PRP and SRP showed gain of temperature at DIPs and less at MCPs after cold challenge. PRP but not SRP patients returned to DIPs basal temperature by the end of re-warming time. Analysis of DDD confirmed that controls and PRP, SRP and AC patients significantly differed in fingers recovery pattern (p < 0.05).
CONCLUSION
IRT appears reliable and reproducible in identifying children with peripheral microvascular disturbances. Our results show that IRT examination pointed out that PRP, SRP and AC patients present significant differences in basal extremities temperature and in re-warming pattern after cold challenge therefore IRT can be suggested as an objective tool for diagnosis and monitoring of disease.

Raynaud's phenomenon and positive antinuclear antibodies as first manifestation of POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes): a case report.
BACKGROUND
POEMS syndrome is a rare paraneoplastic syndrome caused by plasma cell disorder almost always lambda restricted. Secondary Raynaud's phenomenon is an overlooked skin manifestation of the disease even though it is present in twenty percent of patients. On POEMS syndrome have not been described positive antinuclear antibodies (ANA) and this could lead to a misdiagnosis of autoimmune disease, mainly systemic sclerosis.
CASE PRESENTATION
A 47-year-old man presented with color changes on fingertips consistent with biphasic Raynaud's phenomenon; an antinuclear antibody test was positive (at 1:320 titers in a speckled pattern) with normal nailfold capillaroscopy. Clinical features of systemic sclerosis were absent. Twenty-four months later, the patient presented symmetric sensorimotor demyelinating polyneuropathy, and he was diagnosed with Guillain-Barre syndrome; treatment with intravenous gammaglobulin had an incomplete response. Raynaud's phenomenon persisted associated with acrocyanosis, white nails, and positive ANA (1:1280 in a nucleolar pattern). POEMS syndrome was suspected, and serum protein electrophoresis (SPEP) was done. The SPEP revealed polyclonal gammopathy, and serum immunofixation showed monoclonal (M)-protein (IgG lambda). Serum vascular endothelial growth factor concentration showed increased levels. The patient was diagnosed with POEMS syndrome, and treatment with lenalidomide and dexamethasone improved the Raynaud's phenomenon, acrocyanosis, and white nails, but the neurological response was partial.
CONCLUSIONS
POEMS syndrome may mimic clinical manifestations of systemic sclerosis v.g. Raynaud's phenomenon, skin thickening, telangiectasia, and positive ANA. Raynaud's phenomenon may precede other clinical manifestations of POEMS syndrome by several months. It is necessary to have a high index of suspicion for the diagnosis, especially in patients with peripheral polyneuropathy and monoclonal paraprotein. The significance of positive ANA in this condition is unknown and deserves further investigation.

BACKGROUND
Hypoglycemia is uncommon in people who are not being treated for diabetes mellitus and, when present, the differential diagnosis is broad. Artifactual hypoglycemia describes discrepancy between low capillary and normal plasma glucose levels regardless of symptoms and should be considered in patients with Raynaud's phenomenon.
CASE PRESENTATION
A 46-year-old female patient with a history of a sleeve gastrectomy started complaining about episodes of lipothymias preceded by sweating, nausea, and dizziness. During one of these episodes, a capillary blood glucose was obtained with a value of 24 mg/dl. She had multiple emergency admissions with low-capillary glycemia. An exhaustive investigation for possible causes of hypoglycemia was made for 18 months. The 72h fasting test was negative for hypoglycemia. A Raynaud's phenomenon was identified during one appointment.
CONCLUSION
Artifactual hypoglycemia has been described in various conditions including Raynaud's phenomenon, peripheral arterial disease, Eisenmenger syndrome, acrocyanosis, or hypothermia. With this case report, we want to reinforce the importance of being aware of this diagnosis to prevent anxiety, unnecessary treatment, and diagnostic tests.
