The authors identify the incidence of Kaposi's sarcoma in the foot, and discuss the increasing incidence of AIDS-related cases, and the increasing chance of mortality when this lesion is seen in patients under the age of 50.

Unlabelled: Non tuberculous mycobacteria (NTM) are important opportunistic infection in patients with AIDS.
Aim: To present 4 cases of disseminated infections by NTM in patients with AIDS.
Results: These cases were associated with prolonged symptoms of fever, weight loss, diarrhea or cough, with hepatosplenomegaly, anemia and thrombocytopenia.

Angiosarcoma of the penis is an exceptionally rare mesenchymal tumor, with only about 30 cases documented in the literature. Because of its rarity and the often nonspecific clinical presentation, histopathological examination plays a critical role in accurate diagnosis. Angiosarcoma of the penis typically arises in the corpus cavernosum but has also been reported in the glans and urethra, often presenting with metastases.

Kaposi Sarcoma (KS) is a vascular tumor originating from endothelial cells and is associated with human herpesvirus 8 (KSHV) infection. It disproportionately affects populations facing health disparities. Although antiretroviral therapy (ART) has improved KS control in people with HIV (PWH), treatment options for advanced KS remain limited.

Oncogenic gamma herpesviruses, including Epstein-Barr Virus (EBV) and Kaposi's Sarcoma-associated Herpesvirus (KSHV), are opportunistic cancer-causing viruses and induces oncogenesis through complex mechanisms, which involves manipulation of cellular physiology as well as epigenetic and epitranscriptomic reprogramming. In this review, we describe the intricate processes by which these viruses interact with the epigenetic machinery, leading to alterations in DNA methylation, histone modifications, and the involvement of non-coding RNAs. The key viral proteins such as EBNA1 and LMP1 encoded by EBV; LANA and vGPCR encoded by KSHV; play pivotal roles in these modifications by interacting with host factors, and dysregulating signaling pathways.
