ABSTRACT
BACKGROUND: Adnexal tumors of the skin are rare neoplasms that encompass a wide range of dermatologic entities. Here, we investigated the pattern of adnexal tumors of the skin in the All African Leprosy and Tuberculosis Rehabilitation and Training Center (ALERT) hospital retrospectively. METHODS: A hospital-based retrospective study was conducted at ALERT from histopathology records in the Armauer Hansen Research Institute (AHRI) pathology laboratory of patients diagnosed with any of the skin adnexal tumors during the time period January 2017 to December 2021. A structured data extraction sheet was used. Data entry was done using EpiData 4.6.0.6. Data were analyzed using SPSS version 25. RESULT: A total of 146 skin adnexal tumors were identified making the magnitude 2.8% of total biopsies. The 3rd decade of life was found to be the most common age group. Male-to-female ratio was 1 : 1.05. Majority of the tumors were benign (82.2%) and had sweat gland differentiation at 48.6%. Poroma (10.9%) was the most frequent tumor, whereas porocarcinoma (6.8%) made up the most frequent malignant tumor. The most common site was the head and neck region (48.6%). Only 21.2% of the tumors were correctly identified clinically. CONCLUSION: The magnitude of skin adnexal tumors is found to be slightly higher than other similar studies which could be because it was carried out in the largest dermatologic center in the country. The most common skin adnexal tumors identified, their localizations, and lines of differentiation are all in line with other studies. Histopathologic examination is mandatory for the accurate diagnosis of these tumors.

A 28-year-old man presented with a partially eroded growth on the back of his right thigh for the last 15 years. Tuberculosis verrucosa cutis and pyogenic granuloma were suspected on clinical examination. Histopathological examination revealed syringocystadenoma papilliferum (SCAP). SCAP is rare on the thigh and a review of the English literature revealed eight cases. Non-descript clinical presentation in an unusual location and the rare linear and segmental variants lead to misdiagnosis. Onset at puberty should alert one to the possibility of the unusual location of SCAP.
