Morphological perspective of skin adnexal tumours: A case series

Abstract

Adnexal or appendageal tumours of skin comprise an important subcategory of cutaneous neoplasms, although thorough understanding of this entity is still in its early stages. The role of immunohistochemistry in diagnosis is particularly limited, and, it is morphology that actually guides pathologists for clinching diagnosis. Here, we present three uncommon cases of skin adnexal tumours- a case of retiform trichoblastoma, trichilemmal carcinoma and sebaceous carcinoma; especially highlighting the morphological approach of diagnosis and the associated clinical implications based on literature review.
