Basal cell adenoma, which belongs to other types of monomorphic adenoma by WHO classification, is a very rare salivary gland tumor.
A case of parotid tumor we experienced was a 73 year old female. It was diagnosed adenolymphoma in the first inspection because of its softness and variation in hardness but it also seemed probably to be a mixed tumor during follow-up.
Finally it was confirmed as basal cell adenoma.The report of its finding in computed tomography and scintigraphy was presented.
