Abstract

Basal cell adenocarcinoma is a extremely rare low grade malignancy of the salivary gland. It is composed of basaloid cells with dark cell, light cells and pale cytoplasm which shows infiltrative growth pattern into adjacent glandular parenchyme. The pathophysiology of basal cell adenocarcinoma is not well known. First hypothesis is a malignant transformation of the monomorphic adenoma and second one is a de novo origin. Metastasis to the regional lymph nodes is rare. Recently, we have experienced a case of basal cell adenocarcinoma with neck metastasis after previous superficial parotidectomy. For this reason we report this rare case discussed with references.
