The Journal of Prosthetic Dentistry Dec 2022Type IV hypersensitivity reactions (Type IV HR) are immune responses mediated by antigen-specific effector T cells.
STATEMENT OF PROBLEM
Type IV hypersensitivity reactions (Type IV HR) are immune responses mediated by antigen-specific effector T cells.
PURPOSE
The purpose of this clinical report and systematic review was to report the clinicopathological features of Type IV HR in the oral mucosa and to present a systematic literature review of case reports and case series of individuals with Type IV HR in the oral mucosa related to contact with dental materials.
MATERIAL AND METHODS
The presented clinical lesions were melanotic macules with burning that affected the internal labial mucosa in contact with composite resin veneer crowns. Histopathological and immunohistochemical analysis of the lesion was performed. The systematic literature review was performed based on a search in 4 electronic databases (PubMed/MEDLINE, Scopus, Web of Science, and Ovid).
RESULTS
Immunohistochemistry showed positivity for CD4, CD8, CD20, CD3, tryptase, and CD117. After conservative treatment, the patient reported improvement of symptoms, and a decrease in the number of inflammatory cells was verified. Twenty-one articles were included in the review. Unlike the present patient, the authors of all the articles recommended radical treatment with the removal of the dental material.
CONCLUSIONS
Type IV HR in oral mucosa is rare, and the assessment of clinical and histopathological characteristics is essential to perform an accurate diagnosis and provide appropriate treatment.

Review
In most dermatological pathologies, the phenomena observed on the skin are a reflection of internal disorders. In patients with associated acral involvement on the dorsal sides of the hands, this "vitiligo phenotype" may lead to the investigation of certain associated pathologies that sometimes have no obvious clinical impact. To assess the link between skin depigmentation and autoimmune pathologies, we conducted a systematic review involving article selection from the PubMed database. Patients with coexisting thyroid pathologies were found to have a predisposition for developing acral vitiligo and depigmentation of the wrists, and autoimmune thyroid pathologies appeared to be the only coexisting autoimmune or inflammatory diseases in vitiligo patients to show a pattern of distribution. The association of concomitant thyroid dysfunction with depigmentation of the hands was found to be so strong that the absence of depigmented macules on the hands may exclude the coexistence of an autoimmune thyroid pathology. Although the frequency of acral involvement in patients with vitiligo and autoimmune pathologies is higher, the mechanism by which thyroid dysfunction influences this distribution pattern remains incompletely elucidated and requires future studies.

We reviewed the prevalence, the likely aetiopathogenesis, and the management of oro-facial mucocutaneous manifestations of Coronavirus Disease-2019 (COVID-19), caused by the Severe Acute Respiratory Syndrome Coronavirus -2 (SARS-CoV-2). English language manuscripts searched using standard databases yielded 26 articles that met the inclusion criteria. In total, 169 cases (75 females; 94 males) from 15 countries with a spectrum of COVID-19 severities were reviewed. Gustatory perturbations were prevalent in over 70%. Mucocutaneous manifestations were reported predominantly on the tongue, palate, buccal mucosa, gingivae, and lips and included ulcers, blisters, erosions, papillary hyperplasia, macules, glossitis, and mucositis. Ulcerative lesions, present in over 50 percent, were the most common oral manifestation. Lesions resembling candidal infections, with burning mouth, were prevalent in 19%. Petechiae and angina bullosa were generally seen, subsequent to COVID-19 therapies, in 11%. Ulcerated, necrotic gingivae were documented in severely ill with poor oral hygiene. These manifestations, present across the COVID-19 disease spectrum, were commonly associated with the immunosuppressed state and/ or the concurrent antimicrobial/steroidal therapies. In summary, a wide variety of orofacial mucocutaneous lesions manifest in COVID-19. They are likely to be secondary to the disease-associated immune impairment and/or pharmaco-therapy rather than a direct result of SARS-CoV-2 infection per se.

PURPOSE
The current study aimed to report cases of McCune Albright syndrome (MAS) with growth hormone (GH) hyper secretion along with a systematic review of literature to elucidate challenges and intricacies in its diagnosis and management.
METHODS
It was a single centre study carried out in individuals with MAS and autonomous GH secretion (AGHS). In addition, a systematic search of literature across three databases (PubMed, Scopus and EMBASE) was performed from inception until May 31, 2021 to identify cases of MAS with AGHS in the pediatric age group (<18 years).
RESULTS
Three cases from authors centre and 42 cases identified from systematic literature review were analysed. Precocious puberty was the most common presenting endocrinopathy seen in 56.8% (25/44) cases, followed by hyperthyroidism (10/45), hypophosphatemia (4/45), and hypercortisolism (2/45). Cranio-facial fibrous dysplasia (CFFD) was seen in all while polyostotic fibrous dysplasia and Café au lait macule was seen in 40/45 (88.9%) and 35/45 (77.8%), respectively. Pituitary adenoma (58.3% microadenoma) was localized in 53.3% (24/45) cases on pituitary imaging. Biochemical and clinical remission of AGHS was achieved in 61.5% (24/45) cases with medical therapy.
CONCLUSION
Diagnosing AGHS in MAS is challenging because of concomitant presence of CFFD, non-GH endocrinopathies associated height spurt and elevated serum IGF-1. GH-GTT should be performed in presence of elevated growth velocity and serum IGF-1 (>1 X ULN) despite adequate control of non-GH endocrinopathies. Medical management can lead to disease control in substantial number of cases and often entails use of multiple agents.

Postepy Dermatologii I Alergologii Jun 2022Primary cutaneous diffuse large B-cell lymphoma (PCDLBCL) after total knee arthroplasty (TKA) is rare.
INTRODUCTION
Primary cutaneous diffuse large B-cell lymphoma (PCDLBCL) after total knee arthroplasty (TKA) is rare.
AIM
The literature that analyses the cutaneous manifestations of PCDLBCL and assesses the effect and the outcome of treatment is scarce.
MATERIAL AND METHODS
We described a case of PCDLBCL after TKA, whose cutaneous mass develops around surgical sites, mimicking a prosthetic joint infection. In addition, we conducted a systematic review of 29 reported cases with PCDLBCL. Primary endpoint for the review was main cutaneous manifestations of PCDLBCL. Secondary endpoint included treatment options of PCDLBCL and optimal therapeutic method.
RESULTS
We found that the main cutaneous manifestations include infiltrative cutaneous lesions such as macules, papules or nodules, some of them presented as ulcerations or formation of vesicles, subcutaneous nodules or both. The treatment options include excision, radiotherapy, chemotherapy, and even "watchful waiting" as spontaneous regression was noted in some cases. Systemic chemotherapy is the most frequent initial treatment approach chosen, of which rituximab is often combined with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy and patients who received systemic rituximab tend to have a better overall survival (OS) time than those who did not.
CONCLUSIONS
PCDLBCL is a rare disease after TKA, however, an early recognition and distinguishing from infection is still needed. Patients with PCDLBCL may profit from rituximab-based chemotherapy, increasing the survival rate, despite the high relapse rate and limited OS time in some cases.

Review
Macular amyloidosis (MA) is a primary localized cutaneous amyloidosis, characterized by amyloid deposition in the papillary dermis. The clinical presentation includes pruritic hyperpigmented macules and patches with a reticulated or rippled pattern, primarily found on the upper back and extremities. Biopsy is an essential diagnostic tool for confirming MA. This systematic review focused on the biopsy outcomes in patients diagnosed with MA.

Reports of chilblain-like lesions (CLL) coinciding with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have been described in the literature, but this phenomenon has not been critically summarized. The aim of this paper is to summarize reports of CLL coinciding with SARS-CoV-2 infection to clarify the prevalence, clinical relevance, and prognostic value of these lesions. A literature search was conducted using the Embase, Pubmed, and Scopus databases from December 2019 to June 16, 2020 using the search terms ("COVID-19" OR "coronavirus" OR "2019-nCoV" OR "SARS-CoV-2") AND ("chilblain-like" OR "COVID toes" OR "acral"). Papers that described skin changes in patients with suspected or confirmed COVID-19 were included. A total of 31 papers were summarized, representing 813 cases of CLL. Available data suggests an equal gender distribution, mean age of 21 years, and median age of 14 years. Mild extracutaneous symptoms were reported in 53% of cases and 47% were asymptomatic. CLL occurred an average of 16 days after extracutaneous symptoms. Patients with CLL were positive for SARS-CoV-2 in 15% of cases. Lesions were mainly described as asymptomatic and/or pruritic erythematous to violaceous acral macules and plaques. Partial or complete resolution occurred in 85% of cases in a mean of 13 days. The most common histologic findings were perivascular and perieccrine superficial and deep lymphocytic infiltrates. Although a causal relationship between CLL and SARS-CoV-2 has not been confirmed, the temporal association and 15% positive SARS-CoV-2 rate in affected individuals should not be ignored.

Hori's nevus is a pigmentation disorder reported mainly in middle-aged Asian women. There is no systematic review addressing its pharmacotherapy. The population for our systematic review was patients with a clinical/histological diagnosis of Hori's nevus (both sex, any age group). We screened five literature databases using relevant keywords. All RCTs, observational studies and case series mentioning at least one intervention and outcome of that intervention were included. Nineteen studies were included in the final systematic review from total 680 identified nonduplicate records. Different forms of laser (alexandrite laser [QSAL and PSAL], Nd:YAG laser [QSNYL high fluence, low fluence, 532 followed by 1064 nm], Er: YAG and Nd:YAG combination, ruby laser [QSRL], CO laser followed by QSRL) and dermabrasion were found to be useful in treatment of Hori' nevus. Among alexandrite lasers, PSAL is more efficacious and safe than QSAL. In case of high fluence QSNYL, hyperpigmentation rate is quite high while low fluence QSNYL requires more number of treatment sessions. The combined 1064 nm + 532 nm protocol is better in terms of efficacy and safety. Er:YAG + Nd:YAG combination have similar efficacy and added advantage of synergistic action and no adverse event.

BACKGROUND
Acute hemorrhagic edema is a skin-limited small-vessel leukocytoclastic vasculitis, which affects infants 4 weeks to 2 years of age and remits within 3 weeks. The diagnosis is made clinically in not-ill appearing children with acute onset of raised annular or nummular eruptions and edema. In this vasculitis, type, distribution, and evolution of the rash have never been systemically investigated. To address this issue, we employed the data contained in the Acute Hemorrhagic Edema Bibliographic Database, which incorporates all reports on acute hemorrhagic edema.
SUMMARY
Key features of rash were documented in 383 children. Annular eruptions in a strict sense, usually targetoid, were reported in 375 (98%) cases (many children also presented polycyclic or arciform eruptions). Nummular eruptions were also very common (n = 358; 93%). Purpuric eruptions and ecchymoses were reported in the vast majority of cases. Macules and wheals were described in a minority of cases. Edema, detected in all cases, was mostly painful, indurated and nonpitting. The following regions were affected, in decreasing order, by annular or nummular eruptions: legs, feet, face, arms, ears, trunk, and genitals. With the exception of feet, which were very often affected, the same distribution was reported for edema. The initial eruption was often a wheal or a macule that evolved into a nummular or an annular eruption. Nummular eruptions successively evolved into annular ones.
KEY MESSAGE
This study carefully characterizes type, distribution, and evolution of skin eruption in acute hemorrhagic edema. The data help physicians to rapidly and noninvasively make the clinical diagnosis of this vasculitis.

Review
Autosomal dominantly inherited neurofibromatosis type I (NF1) is a systemic disorder caused by a mutation of a gene on chromosome 17q11.2 and characterized by multiple café-au-lait spots, lentiginous macules, Lisch nodules of the iris, and tumors of the nervous system. Bony manifestations such as scoliosis, dysplasia of the greater sphenoidal wing, tibial pseudoarthrosis, short stature, and macrocephaly have been reported in approximately 50% of patients. However, calvarial bone defects are rare. After screening 324 articles, 23 cases (12 adult and 11 pediatric patients) of occipital bone defects in NF1 patients were selected. All patients had a single/multiple bone defect over the lambdoid suture. Adjacent benign plexiform neurofibromas were observed in 14 patients (60.8%, 7 adults and 7 children); one adult patient was diagnosed with neurofibrosarcoma. Meningoencephalocele over the occipital defect was noted in 8 cases (34.78%, all adults). Cranioplasty was performed in only 17.39% of patients. Histologic examination was performed in 7 of the 15 patients with associated neurofibromas/neurofibrosarcomas. Biopsy of the bone margins surrounding the defect was performed in only one case. Pathologic examination of the herniated parieto-occipital or cerebellar tissue was not performed in any of the patients studied. We report the case of a 9-year-old girl with NF1 and a significant occipital bone defect and performed a systematic review of the relevant literature to highlight the challenges in treating this condition and to investigate the underlying mechanisms contributing to bone defects or dysplasia in NF1.
