ABSTRACT

The salivary glands are an uncommon site of neoplasms. The percentage of basal cell adenomas is only 0.2%-2% of all the salivary gland tumors. The basal cell adenoma is an epithelial neoplasm with a monomorphic histological aspect, with a predominance of basalod cells. The growth pattern could be solid, tubular, trabecular, membranous or analog dermic. In our casuistry only we have one case with this histopathologic diagnosis; and with an atypical localization, because the most frequent localization is at the parotid gland. We only found in the bibliography six cases with these characteristics. The paper describes a case with atypical localization of an almost exclusively neoplasm of the parotid gland. Normally this is not included in the battery of the differential diagnosis of tongue base tumor. There is not enough epidemiologic information to establish incidence by gender and age distribution. The possible differential diagnosis of this neoplasm is the pleomorphic adenoma, canalicular adenoma, basal cell adenocarcinoma, a solid subtype of a cystic adenoid carcinoma and a basaloid variation of a squamous cell carcinoma. The treatment of choice is the surgical one (excisional biopsy), based on pathology data of the mayor salivary gland. It is important to make a complete dissection of the neoplasm to diminish the possibility of recurrence.
