ABSTRACT
Sebaceous carcinoma (SC) is an aggressive malignant adnexal tumour, which tends to be an exception in adults, more so in males. Common among the females, in seventh decade, the extraocular type of SC usually occurs over the face and scalp. They are derived from the sebaceous gland epithelium. Although no obvious aetiology is identified, a few cases show association with Muir-Torre syndrome (MTS). It has a diverse clinical presentation which often causes it to be mistaken for common benign entities.10 The definite diagnosis is confirmed on histopathology. The characteristic histologic criteria include lobular architecture, foamy vacuolization of the cytoplasm, nuclear pleomorphism, and mitotic activity.
Key words: Sebaceous carcinoma, malignant adnexal tumour, extra-ocular, scalp.
