Pattern of Skin Cancers in a Tertiary Medical Center in Southwest Nigeria

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

Anal Melanoma: A Case Report of a Rare and Lethal Malignancy in a Suburban Nigerian Teaching Hospital

The aim of this report is to highlight the challenges involved in the diagnosis and treatment of anal melanoma in a tertiary hospital in Nigeria. It is a case report of an 84-year-old man who was managed for anal malignant melanoma. Despite inadequate investigative tools and less radical surgical treatment, the survival period of the index patient was comparable to the median survival quoted in the literature. Despite its rarity, mucosal melanomas also occur in the tropics. Prompt diagnosis, adequate imaging, and standardized treatment may improve its outlook in the nearest future

Kaposi Sarcoma among HIV Infected Patients in Lagos University Teaching Hospital, Nigeria: A 14-Year Retrospective Clinicopathological Study

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

Neonatal neuroblastoma with adrenal primary and metastasis to the liver: A case report and a review of literature

We report the case of a 23-day-old neonate with neuroblastoma (NBL) in the right adrenal gland and widespread metastases to the liver. This raises the possibility of foetal NBL, which was missed during periodic ultrasonography done during the mother's pregnancy. We hope that this report would increase the awareness of physicians about foetal, congenital and neonatal NBL; and of sonographers about space-occupying lesions in the foetus. The clinicopathologic features and the management of neonatal NBL are discussed

Small intestinal obstruction due to subserosa fibrolipoma in a 2-year-old child: A case report and literature review

Lipomas of the gastrointestinal tract (GIT) are generally rare. They are rare in children, and when they occur they are usually submucosa. Most of the submucosa lipomas of GIT are present in the colon (65%–75%) and small intestine (25%). In children, intestinal lipoma is a documented cause of pathological lead point intussusception, especially when located in the submucosa. The present case report is of subserosa lipoma in the distal ileum. A 2-year-old boy presented with features of intestinal obstruction which was preceded by a painless abdominal mass. In the absence of computerised tomography scan, he was operated, and histopathology examination confirmed the mass as pedunculated fibrolipoma arising from the subserosa and causing extrinsic compression of the ileum
