Abstract

Ceruminous glands are specialized apocrine glands located in the external auditory canal (EAC). Pleomorphic adenoma (PA) of the EAC is derived from these ceruminous glands. Tumors arising from these ceruminous glands are rare. Furthermore, ceruminous PA of the EAC is extremely rare. About 35 cases have been reported to date in the English literature, and only 4 cases have been reported in Korea. There are several controversial issues about these rare tumors such as nomenclature, histogenesis and classification. We report here on two cases of ceruminous PA and review the cases in the Korean literature.
