Cutaneous sebaceous carcinoma presenting as a fungating breast tumour

Abstract

Background: Sebaceous carcinomas are rare malignant tumours which can either arise from, or differentiate into sebaceous glands. They are subclassified into ocular and extraocular subtypes and most commonly occur in the head and neck region. Tumours below the neck occur infrequently, and most commonly resemble benign skin lesions such as pyogenic granulomata and molluscum contagiosum, or malignant skin tumours like basal and squamous cell carcinomas.
