Abstract

Sebaceous carcinoma (SC) is a highly malignant tumour derived from the sebaceous glands. SCs have traditionally been divided into two categories, ocular and extraocular. Tumours arising in extraocular sites are rare and less aggressive than SCs of the eyelid. SC of the nasal vestibule is a very rare pathology, and for today there have been only a few reported cases worldwide. Here, we report a case of a 60-year-old man who presented with a 1-month history of a painful, recurrent bleeding tumour in the right nasal vestibule. Based on the histologic findings, a diagnosis of sebaceous carcinoma of the nasal vestibule was established. We discuss incidence as well as clinical, histologic, diagnostic, prognostic, and management issues of this aggressive neoplasm.
