Verruca vulgaris is a cutaneous infection predominantly caused by human papillomavirus (HPV) type 1, 2, and 4. In immunocompromised individuals infected with human immunodeficiency virus (HIV) infection, HPV leads to a higher prevalence of infections and also has a greater likelihood of being infected with atypical types such as genital-associated HPV in extragenital sites. This case report describes a 48-year-old male patient who presented with skin-colored verrucous papules on the hands and feet, with no evidence of genital lesions.

Individuals with human immunodeficiency virus (HIV) infection are prone to developing persistent and unremitting anogenital warts (AGWs). To address this health condition, immunotherapy using tuberculin purified protein derivative (PPD) has been proven to be a promising novel and safe treatment for AGWs in HIV patients. Therefore, this study involved a case of a 21-year-old man with stage I HIV infection, possessing CD4 counts 548 cells/uL and routinely receiving HIV antiretroviral.

Background: Acral and mucosal melanomas, the most common sun-shielded site melanoma subtypes in Asia and Indonesia, often yield poor prognoses. The invasion depth reflects their progressivity, and the pathogenesis is influenced by vitamin D receptor (VDR) status and CD8+ T-Lymphocyte amount. This study aims to determine the association between the invasion depth of acral and mucosal melanomas with their VDR and CD8+ immunoexpression.

Article Synopsis
  • - Familial Reactive Perforating Collagenosis (FRPC) is a rare, benign skin condition primarily seen in young children, with fewer than 50 documented cases, and its causes and treatments remain unclear.
  • - A case study of a 20-year-old male from Indonesia showed multiple skin papules across his body for over 7 years, and similar symptoms were present in his family.
  • - The patient was successfully treated with a topical corticosteroid, desoximetasone, leading to significant improvement in skin lesions, suggesting corticosteroids could be a viable treatment for FRPC.

Introduction: Sub-Saharan Africa (SSA) is plagued by myriads of diseases, mostly infectious; but cancer disease burden is rising among non-communicable diseases. Nigeria has a high burden of cancer, however its remote underserved culturally-conserved populations have been understudied, a gap this study sought to fill.

Methods: This was a cross-sectional multi-institutional descriptive study of histologically diagnosed cancers over a four-year period (January 2019-December 2022) archived in the Departments of Pathology and Cancer Registries of six tertiary hospitals in the northeast of Nigeria.
