The migration of squamous epithelium of external ear through a tympanic membrane perforation into the middle ear forms a cholesteatoma. But it is extremely a rare condition to observe extensive cholesteatoma on the medial surface of tympanic membrane with perforation. This condition is termed tympanic membrane cholesteatoma (TMC). We herein present an exceptional case of extensive TMC with marg...
