The patient was diagnosed with an intratympanic membrane congenital cholesteatoma
(CC) can occur in any part of the temporal bone and the commonest site being in the middle ear, most probably due to its early presentation with conductive hearing loss [1, 2].
Past medical history was remarkable for surgical excision of a congenital cholesteatoma
and insertion of transtympanic tubes to correct a conductive hearing loss.
The mass was excised, and the pathology report confirmed the diagnosis of a congenital cholesteatoma
9) Yamasoba et al proposed that osteoma may be of a congenital nature, based on their reported case of an osteoma that was seen in conjunction with congenital cholesteatoma

in the tympanic membrane
presents in children as a white mass behind an intact tympanic membrane.
6) Yamasoba et al, who reported a case of osteoma arising from the pyramidal eminence combined with congenital cholesteatoma
, suggests a congenital mechanism.
If the affected patient has no history of chronic otitis media or otologic surgery, the otolaryngologist can make the diagnosis of congenital cholesteatoma
Based on his age, we believe his tumor was not a congenital cholesteatoma
