A Case of Basal Cell Adenocarcinoma in the Parotid Gland / 대한이비인후과학회지

ABSTRACT

Basal cell adenoma of salivary gland is an established variant of monomorphic adenoma. Few cases of malignant basal cell neoplasms have appeared in the literature. Basal cell adenocarcinoma has not only morphologic characteristics of the basal cell adenoma but also infiltrative, perineural and intravascular growth features that indicate a malignant potential. Some cases of these tumors which metastasized to the lymph nodes and lung have been reported. The peak incidence of age is in the fifth decade of life, and there is no gender predilection. The parotid gland is a predominant site of involvement. The authors have experienced such case of basal cell adenocarcinoma, which was presented by a single parotid mass. The tumor was removed by total parotidectomy with preservation of the facial nerve.
