Plantar melanomas have more aggressive clinicopathological characteristics and higher mortality rates than melanomas in other anatomical regions. To compare clinicopathological features and define prognostic factors between melanoma in the plantar region and melanoma at other anatomical sites. A retrospective comparative analysis was conducted on all cutaneous melanoma patients seen at a tertiary referral center over 20 years.

Article Synopsis
  • Epidermodysplasia verruciformis (EV) is a rare skin condition linked to β-human papillomaviruses (HPV) in immunodeficient individuals, presenting as flat warts and pityriasis-like lesions.
  • The study details three patients from two families with syndromic EV, identified through whole exome sequencing to have new homozygous variants in the STK4 gene, resulting in a premature stop codon.
  • STK4 deficiency causes a combined immunodeficiency leading to increased susceptibility to various infections and autoimmune issues, as evidenced by immunophenotyping showing significant CD4 T cell deficiency in the patients.

Article Synopsis
  • - This study examines the effects of long-term exposure to sulfuric acid (SA) on skin health in mice, focusing on its potential to cause cancer over a 16-week period.
  • - Results showed that chronic exposure resulted in skin changes like inflammation, increased skin thickness, and early signs of cancer, demonstrated by elevated markers such as p53 and Ki-67.
  • - The research highlights that SA exposure leads to oxidative stress in the skin, emphasizing the need for better safety measures for people working with or around sulfuric acid.

OTULIN encodes an eponymous linear deubiquitinase (DUB) essential for controlling inflammation as a negative regulator of the canonical NF-κB signaling pathway via the regulation of M1-Ub dynamics. Biallelic loss-of-function (LOF) mutations in OTULIN cause an autosomal recessive condition named Otulin-Related Autoinflammatory Syndrome (ORAS), also known as Otulipenia or AutoInflammation, Panniculitis, and Dermatosis Syndrome (AIPDS). Monoallelic OTULIN LOF, also known as OTULIN Haploinsufficiency (OHI) or Immunodeficiency 107 (IMD107), has been linked to an incompletely penetrant, dominantly inherited susceptibility to invasive Staphylococcal infections.

Skin cancer is the most widespread type of malignant tumor representing a major public health concern. Considering the numerous side effects associated with conventional treatments, phytotherapy may be regarded as a viable medicinal alternative. This study aimed to investigate the therapeutic potential of (L.

Introduction: Uveal melanoma (UM) is a rare yet deadly tumor. It is known for its high metastatic potential, which makes it one of the most aggressive and lethal cancers. Recently, immune checkpoints such as Programmed cell Death protein-1 (PD1) and Cytotoxic T-Lymphocyte-Associated significantly increasing patient survival in multiple human cancers, especially cutaneous melanoma.

Article Synopsis
  • A study conducted at Ibn Rochd University Hospital-Casablanca from 2017 to 2021 found that unusual viral skin infections were often the first signs of inborn errors of immunity in children, affecting 1.3% of patients with suspected IEI.
  • The research involved 591 newly diagnosed patients, identifying specific genetic deficiencies like GATA2, STK4, and COPA in some, linked to chronic or resistant viral skin infections.
  • The study emphasizes the importance of recognizing these skin infections as potential indicators of underlying immunological issues, which could improve diagnosis and treatment for affected children and their families.

Lichen planus pemphigoid (LPP) is a rare autoimmune bullous dermatosis, although it is frequently idiopathic, the induced form is rare and there are few inducing drugs. We report a case of LPP induced by a gliclazide. A 68-year-old female patient with type 2 diabetes on gliclazide for three months presented with an eight-week history of generalized erythematous-papular eruption.

Verrucous melanoma (VM) is a rare entity that presents diagnostic difficulty on both clinical and histopathologic grounds. Clinically, this tumor can be mistaken for a benign non-melanocytic lesion, particularly seborrheic keratosis (SK), as they both share several similarities, such as the homogenous pigmentation, the verrucous surface, and the roughly well-defined borders. In our patient's case, her verrucous lesion was initially misdiagnosed as SK by a general practitioner two months prior to her admission.

Primary cutaneous aggressive epidermotropic CD8+ T-cell lymphoma is a rare entity representing less than 1% of cutaneous lymphomas. It has an aggressive clinical manifestation with a poor prognosis. It is characterized by cytotoxic and epidermotropic CD8+ proliferation.

Introduction: breast cancer (BC) is a malignancy with very high incidence and mortality in Africa, especially in Western Africa, where more than 25 thousand deaths are registered every year. Not all BC have the same prognosis, and being able to personalize treatment and predict aggressiveness is of crucial importance. The purpose of our study is to explore further subdivisions associated with prognosis, beyond breast cancer molecular classification that is routinely established in pathology departments.

Papulonodular mucinosis is a rare but well-documented finding associated with systemic and cutaneous forms of lupus erythematosus (LE). It occurs exceptionally in association with subacute cutaneous lupus erythematosus (SCLE). Its etiology and pathogenesis remain to be elucidated.

Autoimmune bullous diseases (AIBDs) are a heterogeneous group of diseases characterized by cutaneous and mucosal vesicles, blisters, and erosions. Several factors can trigger this disease, including vaccines; but this entity remains very rare. We hypothesized that vaccination against coronavirus disease 2019 (COVID-19) could trigger an immunological response in genetically predisposed individuals.

Background: The proliferating and malignant proliferating trichilemmal cysts (MPTC) are rare adnexal tumors. We report 3 cases through which we will detail the anatomo-clinical characteristics of these tumors.

Cases: Two patients, 60 and 56 years old, consulted for multiple scalp nodules, one of which had changed with the appearance of a central ulceration.

Ungueotropic mycosis is a rare form of mycosis fungoides. We present the case of a 32-year-old female patient with advanced tumor stage mycosis fungoides, presenting a phanerial involvement with lymphoid infiltration of the nails and scalp confirmed by histology and immunohistochemistry.

Article Synopsis
  • Cutaneous cryptococcosis affects 10-15% of patients with disseminated cryptococcosis and can look like various skin lesions, but its relation to nails has not been documented before.
  • A 28-year-old HIV-positive woman had a unique case of subungual cryptococcosis, presenting as an ulcerated nodule, which was treated with excisional biopsy showing granulomas and encapsulated yeast cells.
  • This case suggests that surgical excision plus systemic therapy is the best approach for nail cryptococcosis, highlighting the importance of recognizing rare skin manifestations in HIV patients as the incidence continues to rise.
