[Sebaceous carcinoma of salivary gland. Report of two cases of infrequent location].

Sebaceous carcinoma is an infrequent tumor of tardy increase, locally aggressive, potentially recurrent, with natural propensity for metastasize, both loco-regional or remote (lymphogenous or hematogenus metastases). Principal sitting are the annexed glands to ocular sense (Zeis glands and specially Meibomian's). Its origin in salivary glands is exceedingly uncommon, only those arising in the parotid have been reported. Our contribution are 2 cases which source were the sublingual gland and a minor palatine salivary gland, respectively. The perusal of the literature has been negative: no one previous case of sebaceous carcinoma could be discovered in the literature.
