Basaloid salivary carcinoma.

The basaloid salivary carcinoma is proposed as the malignant counterpart of the basal cell or basaloid monomorphic adenoma. The carcinoma can arise de novo or by evolution from a maternal monomorphic adenoma. Particularly at risk for the latter sequence is the dermal analogue monomorphic adenoma. Preponderantly a parotid gland neoplasm, the basaloid carcinoma appears to be a biologically low-grade carcinoma with a low mortality but with a respectable local aggressiveness and recurrence rate.
