Background. Despite the increased incidence of Kaposi sarcoma (KS) resulting from the Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) pandemic, there is still significant underreporting of KS in this environment. Objectives. This study was aimed at determining the incidence and clinicopathologic patterns of KS among HIV infected patients in Lagos University Teaching Hospital (LUTH), Nigeria, over a 14-year period: January 2000 to December 2013. Methodology. The materials for this study included patients' hospital clinical files, duplicate copies of histopathologic reports, and tissue blocks and corresponding archival slides in the Anatomic and Molecular Pathology Department and the HIV/AIDS unit of the Department of Haematology. Results. Within the study period, 182 cases of KS were diagnosed, accounting for 1.2% of all patients managed for HIV/AIDS and 2.99% of solid malignant tumours. The male-to-female ratio and modal age group were 1 : 1.3 and 5th decade, respectively. Most cases (90%) had purely mucocutaneous involvement with the lower limb being the commonest site (65.8%). The majority of lesions were plaques (65.8%). Vascular formation was the predominant histologic type seen (43.5%). Conclusion. KS in Lagos followed the same epidemiologic trend as other centers in Nigeria, with an increasing incidence in this era of HIV/AIDS.

Background: Skin cancers are the most common malignancies in the western world, and their incidence is increasing globally. However, the data about the pattern in sub-Saharan Africa are limited. This study evaluates the pattern of primary skin malignancies in a tertiary medical center located in a sub-urban area. Methods: The histo-pathological records of patients managed for malignancies from January 2012 to December 2020 were retrieved from the pathology department of a tertiary medical center in Ekiti State, Southwest Nigeria. All primary skin cancers seen within this study period were extracted from the records and then reviewed retrospectively. Results: The male-to-female ratio of primary skin malignancies was 1:1.06, and the mean age of patients was 57.2 ± 17years. All patients were black Africans who were mainly of the Yoruba ethnicity (97.2%). Squamous cell cancer had the highest frequency (34.7%), followed by melanoma (27.8%), dermatofibrosarcoma (12.5%), and basal cell carcinoma (11.1%). The most commonly affected anatomic region is the lower limbs (50.6%). Conclusion: The pattern of primary skin cancers seen in black Africans differ from that of Caucasians: however, larger community-based studies in our environment is recommended to provide more conclusive information about the pattern of skin cancers.

Background Leiomyomas are benign smooth muscle tumours predominantly found in the uterus. Rarely, they may be located in the ovaries, scrotum, bladder, lungs, vascular structures and spermatic cord. Case presentation We managed a 39-year-old man who presented with a year history of progressive right-sided hemiscrotal swelling. The right scrotal mass was excised, and histology showed scrotal leiomyoma. Conclusion Scrotal leiomyoma is very rare and challenging to diagnose pre-operatively as a cause of scrotal swelling, but it is amenable to surgical excision.
