A clinico-histopathological study of skin appendageal tumours in a tertiary health care centre in western Odisha– A case series

Abstract

Skin appendageal tumours (SATs) are those neoplasms that arise from pilosebaceous, apocrine, or eccrine sweat glands. These are a diverse group of tumours with both benign and malignant counterparts. They can be single, multiple, or have a syndromic association with internal malignancies. Benign adnexal tumours are more common, while malignant adnexal tumours are rare, usually locally aggressive, and have the potential for nodal involvement and distant metastasis with a poor clinical outcome. Therefore, proper diagnosis of SATs is important for therapeutic and prognostic reasons.This study aims to determine the clinico-histopathological correlation in cases of SATs in our hospital. It is a case series conducted over a one-and-a-half year period from January 2021 to July 2022. All clinically suspected cases of SATs were examined, biopsied, and subjected to histopathological examination. Histopathologically confirmed cases of SATs were finally analysed. Among twenty-four thousand two hundred twenty-four new patients attending OPD, 30 suspected cases of ATs underwent histopathological examination. Histopathology was confirmatory in only 12 cases (40%). 10 cases were benign, and two were malignant. Out of 10 benign cases, hidradenoma was noted in 3 (25%), trichoepithelioma in 2 (16%), proliferating pilar tumour, apocrine hidrocystoma, steatocystoma multiplex, hidradenoma papilliferum, and pilomatrixoma were seen in one each. Females (75%) outnumbered males (25%) in our study population.: SATs are infrequent and are not frequently observed in the field of surgical pathology. Histopathology is the gold standard for diagnosis.
