Mpox is caused by the Monkeypox virus, which belongs to the Orthopoxvirus genus and Poxviridae family. The Monkeypox virus was first identified as a cause of disease in humans in the 1970s in the Democratic Republic of the Congo. Mpox was considered endemic in several African countries. A global outbreak of Mpox was first recognized in Europe in May 2022 and was declared a public health emergency of international concern on July 23, 2022. The first reported Mpox case in Indonesia was in October 2022 which was identified as an imported case, there were no new confirmed Mpox cases until 13 October 2023. Since then there were 72 cases of confirmed Mpox cases in Indonesia by the end of 2023, distributed across 6 provinces, mostly in the Java island.We present two different spectrums of Mpox skin lesions in patients living with HIV, with a positive polymerase chain reaction test for Mpox. The first patient is a 48-year-old male, who developed a maculopapular lesion, that was initially noticed on the face, the lesions were then spread to the back and hand. He identifies as men who have sex with men and living with HIV for the past 18 years. There were no lesions on the genitalia or mucosa. The second patient is a 28-year-old male, the initial symptom was fever, followed by skin lesions after around 1 week of fever. The lesion initially appears as pustules on the face and then spreads throughout the whole body, the lesions also grow larger and become pseudo-pustules and ulcers. There were also mucosal involvements in the mouth, making oral intake difficult. This patient also identified as men who have sex with men with multiple partners, HIV status was not known at the initial presentation. HIV screening was done with positive results.

BACKGROUND
Osteopoikilosis, also referred to as disseminated condensing osteopathy, spotted bone disease, or osteopecilia, is a rare bone disorder. The case presented here showcases multiple disc lesions in the spine, extensive multifocal skin lesions, and positive test results for dermatomyositis and multifocal enthesopathy, accompanied by neurological symptoms. This manifestation represents a novel variant of the disease.
CASE PRESENTATION
Our patient is a 46-year-old mosque Kurdish servant presenting with complaints of pain in the right leg, lower back, right hand, and neck. Additionally, the patient has been experiencing redness in the right buttock and ipsilateral thigh, as well as gradually expanding and stiffening skin lesions on the left shin for the past 3 weeks. Painful neck movements and a positive Lasegue test were also observed in the right leg. The patient reports pain in the right buttock accompanied by a substantial erythematous area with induration measuring 8 × 15 cm, as well as an erythematous and maculopapular lesion measuring 6 × 18 cm on the left shin.
CONCLUSIONS
Our patient is a 46-year-old man presenting with complaints of skin lesions and pain in the lower back, pelvis, neck, and limbs. The X-ray reveals shoulder, pelvis, knee, and ankle involvement, while spinal involvement is observed in the neck and lumbar region. Furthermore, the bone scan indicates extensive enthesopathy in various regions, a unique manifestation not previously reported in similar cases.

Review
Chikungunya is a viral disease transmitted by female Aedes mosquitoes that has been increasingly reported in many parts of the world across the geographical borders. In addition to fever and joint pain, mucocutaneous manifestations of chikungunya have been reported in 40-75% of infected patients. Dermatological manifestations of chikungunya are often under-recognized and misdiagnosed as clinicians are not sensitized or educated regarding these. The early-onset cutaneous manifestations of chikungunya fever, occurring within 1 month of the fever, include maculopapular rashes, vesiculobullous eruptions, Steven-Johnson syndrome/toxic epidermal necrolysis-like eruptions, flagellate lesions, scrotal dermatitis, oro-genital ulcers, and exacerbation of preexisting dermatoses like psoriasis. Hyperpigmentation, lichenoid eruptions, diffuse hair fall, and exacerbation of acne usually occur as a late manifestation. Diagnosis of these mucocutaneous manifestations can be challenging as they often resemble other common dermatoses. This review article elaborates on various mucocutaneous manifestations of chikungunya fever, based on literature review and authors' clinical experience.

Review
Composite lymphoma (CL) involving B-cell lymphoma and T-cell lymphoma is extremely rare. Herein, we report three such cases using immunohistochemistry, flow cytometry, and the next-generation sequencing (NGS) to identify the pathological and molecular characteristics of CL. In the first case, the patient was admitted to hospital for generalized pruritic maculopapular rash over the whole body. An excisional biopsy of the skin lesions showed T-cell lymphoma. At the same time, the staging bone marrow (BM) biopsy revealed a diffuse large B-cell lymphoma (DLBCL). After R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) therapies, the patient produced a good response with substantial dissipation of the rashes and relief of skin. The other two patients were admitted to hospital due to lymphadenopathy and were diagnosed with DLBCL and follicular lymphoma (FL) after core needle biopsy of lymph nodes, BM biopsy, BM aspiration, and flow cytometry. Following R-CHOP and R-COP (rituximab, cyclophosphamide, vincristine, and prednisone) therapies, they achieved complete remission unconfirmed (CRu) and complete remission (CR). However, one or two years later, they suffered a relapse of lymphadenopathy. The shocking fact was that re-biopsy of lymphadenopathy revealed peripheral T-cell lymphoma (PTCL) and angioimmunoblastic T-cell lymphoma (AITL). NGS findings identified DNA methyltransferase 3a (), isocitrate dehydrogenase 2 (), Ras homolog gene family, member A (), splicing factor 3B subunit 1 (), and tumor protein p53 () mutations. After immunochemotherapy, these patients achieved CRu and CR again. Nevertheless, they suffered a second relapse of T-cell lymphoma. Finally, they died due to progression of disease. We found that the occurrence of CL is associated with Epstein-Barr virus infection and , , and mutations, and the prognosis of the disease is closely related to the T-cell lymphoma components.

Review
Mastocytosis is a complex heterogenous multisystem disorder that is characterized by pathologic activation or accumulation of neoplastic mast cells (MCs) in one or more organs. This clonal MC expansion is often associated with a somatic gain-of-function mutation (D816V in most of the cases) in the KIT gene, encoding for the MC surface receptor KIT (CD117), a stem cell growth factor receptor. Based on clinical and biochemical criteria, the World Health Organization (WHO) divided mastocytosis into different subclasses. The exact prevalence of mastocytosis remains elusive, but it is estimated that the disease affects approximately 1 in 10,000 persons. The clinical presentation of mastocytosis varies significantly, ranging from asymptomatic patients to a life-threatening disease with multiple organ involvement, potentially leading to cytopenia, malabsorption, hepatosplenomegaly, lymphadenopathy, ascites or osteolytic bone lesions with pathological fractures. Patients with mastocytosis may experience symptoms related to release of MC mediators, such as flushing or diarrhea or even more severe symptoms such as anaphylaxis. Recently, a new genetic trait, hereditary alpha tryptasemia (HaT), was described which involves a copy number variation in the TPSAB1-gene. Its role as standalone multisystem syndrome is heavily debated. There is emerging evidence suggesting there might be a link between HaT and due to the increased prevalence of HaT in patients with SM. The aim of this review is to provide a practical roadmap for diagnosis and management of mastocytosis and its associated entities, since there are still many misconceptions about these topics.

Review
BACKGROUND
Mastocytosis is characterized by an accumulation of clonal mast cells (MCs) in tissues such as the skin. Skin lesions in mastocytosis may be clinically subtle or heterogeneous, and giving the correct diagnosis can be difficult.
METHODS
This study compiles personal experiences together with relevant literature, discussing possible obstacles encountered in diagnosing skin involvement in mastocytosis and cutaneous mastocytosis (CM).
RESULTS
The nomenclature of the term "CM" is ambiguous. The WHO classification defines CM as mastocytosis solely present in the skin. However, the term is also used as a morphological description, e.g., in maculopapular cutaneous mastocytosis (MPCM). This is often seen in systemic, as well as cutaneous, mastocytosis. Typical CM manifestations (MPCM), including mastocytoma or diffuse cutaneous mastocytosis (DCM), all share a positive Darier's sign, and can thus be clinically recognized. Nevertheless, distinguishing monomorphic versus polymorphic MPCM may be challenging, even for experienced dermatologists. Less typical clinical presentations, such as MPCM with telangiectatic erythemas (formerly called telangiectasia macularis eruptiva perstans), confluent, nodular or xanthelasmoid variants may require a skin biopsy for histopathological confirmation. Because MC numbers in CM have a large overlap to those in healthy and inflamed skin, detailed histopathological criteria to diagnose mastocytosis in MPCM are needed and have been proposed. D816V mutational analysis in tissue is helpful for confirming the diagnosis. Biomarkers allow the prediction of the course of CM into regression or evolution of the disease. Further diagnostic measures should screen for concomitant diseases, such as malignant melanoma, and for systemic involvement.
CONCLUSIONS
Whereas in typical cases the diagnosis of CM may be uncomplicated, less typical manifestations may require specific investigations for making the diagnosis and predicting its course.

Review
Cyclin-dependent kinase (CDK) 4/6 inhibitors (palbociclib, ribociclib and abemaciclib) have revolutionized the treatment of metastatic breast carcinoma. They currently form the first-line treatment, in combination with endocrine agents, for the management of locally advanced or metastatic hormone receptor-positive (HR + ), human epidermal growth factor receptor 2-negative (HER2-) breast cancer, the largest subtype of breast carcinoma. CDK 4/6 inhibitors have shown comparable efficacy outcomes with predictable and manageable adverse events. In this setting, dermatologic toxicity appears to be relatively frequent, accounting for up to 15% of all reported adverse events. It is usually mild to moderate in intensity and does not normally constitute a dose-limiting toxicity. The range of dermatologic adverse events includes both non-specific entities (maculopapular rash, pruritus, alopecia) and more characteristic toxicities related to CDK4/6 inhibitors, such as vitiligo-like lesions or cutaneous lupus erythematosus. Finally, more severe or life-threatening skin reactions can occasionally occur. The main dermatologic manifestations associated with CDK4/6 inhibitors, as well as management thereof, are described in this comprehensive review.

A male in his 60s developed a pruritic, maculopapular rash on his torso and arms, sparing his palms and soles. He tested positive for ANA and an initial skin biopsy identified "bullous lupus," supporting the diagnosis of a connective tissue disease. Additional symptoms included headaches, facial nerve palsy and hearing loss, which partially responded to oral corticosteroids. He subsequently developed a steroid-dependent left eye scotoma, neuroretinitis and optic nerve papillitis. Mycophenolate mofetil was added but an attempted oral steroid taper led to a worsening rash, progressive retinitis and papillitis. Neurosyphilis was confirmed by serum positive rapid plasma reagin test, reactive treponema pallidum antibodies, positive cerebrospinal fluid venereal disease research laboratory and positive spirochete immunostain of skin biopsy of lesional (rash) tissue. Treatment with intravenous ceftriaxone resolved his rash and visual symptoms. It is important to consider syphilis as a mimicker of connective tissue diseases.

WMJ : Official Publication of the State... Dec 2023Cutaneous manifestations before other symptoms have great potential for early COVID-19 diagnosis to prevent surge.
INTRODUCTION
Cutaneous manifestations before other symptoms have great potential for early COVID-19 diagnosis to prevent surge.
METHODS
We conducted a search of PubMed and Embase databases through April 11, 2021 to include 39 studies reporting skin manifestations occurring prior to any other COVID-19 symptoms in laboratory-confirmed cases.
RESULTS
Ninety-seven patients were included. Urticarial (24.7%) and maculopapular (22.7%) lesions were most common, followed by pernio (17.5%), vesicular (14.4%), papulosquamous (8.2%), and purpuric (5.1%) lesions. Cutaneous to systemic symptom latency ranged from 2 to 20 days in cases that reported it (26%), while skin lesions were the only presentation in 23 cases (23.7%). Skin lesions were the only COVID-19 manifestation in 58.8% of pernio, 40% of vesicular, 16.6% of urticarial, 18.2% of maculopapular, and 12.5% of papulosquamous presymptomatic cases. Although sample size is limited, all purpuric cases developed other symptom(s) later.
CONCLUSIONS
Pernio and purpuric lesions have been well-associated with COVID-19, but papulosquamous, vesicular, mild maculopapular, and urticarial lesions can easily be dismissed as unrelated to COVID-19. Pernio lesions are thought to be related to strong immune response and low contagiousness, while purpuric and vesicular cases are speculated to be related to higher SARS-CoV2 viral load, severity, and contagiousness. All rashes, even without other symptoms, should necessitate high level of suspicion for isolation or contact tracing.
