title: Sebaceous lymphadenocarcinoma of parotid gland.
abstract: The sebaceous lymphadenocarcinoma of the salivary glands is extremely rare and represents carcinomatous transformation of sebaceous lymphadenoma. There are only four reported patients in the medical literature. A patient who presented with a recent increase of a left infraauricular mass, of more than 10 years duration, underwent surgery. The microscopic examination revealed a typical sebaceous lymphadenoma with transition to a sebaceous adenocarcinoma. After postoperative adjuvant radiotherapy, the patient remains disease-free at 24 months postoperatively. We here report a fifth case of this tumor and the youngest age at diagnosis among reported cases.
