A very rare case of a sebaceous carcinoma of the external auditory canal with basal cell differentiation is presented. Fewer than 400 cases affecting any part of the body have so far been reported and of that only seven cases have been known to involve the external auditory canal. The clinical features, pathology and treatment are described and the relevant literature has been reviewed.

Sebaceous carcinoma arising from the buccal mucosa is very rare. Only one such case has been reported in the English literature. We report a second case arising in an 11-year-old girl.

A case of supraglottic laryngeal squamous cell carcinoma with sebaceous differentiation in a 68-year-old Caucasian male is described. A right cervical lymph node metastasis, excised during the laryngectomy operation, consisted exclusively of squamous cells. Despite intensive post-operative chemotherapy. the patient developed metastatic foci in the left cervical area and left pulmonary hilus and died seven months later. This is the second case report of a laryngeal squamous cell carcinoma with sebaceous differentiation in the literature.

Carcinomas of the sebaceous glands of the skin are uncommon. These tumours metastasize frequently. A case of cutaneous sebaceous carcinoma localized in the postauricular region is presented with its exceptional large size and very poor prognosis.
