A Rare Combination of Acquired Lymphangioma of the External Auditory Canal and Cholesteatoma in the Middle Ear Cavity.

Lymphangioma (LM) is a rare but benign tumor derived from lymphatic malformation, which is extremely rare in the auditory canal or middle ear cavity. We presented a case of acquired lymphangioma of the external auditory canal combined with cholesteatoma in the middle ear cavity. To our best knowledge, this is the first case of combined lesions of lymphangioma and cholesteatoma in English literature.
