[Malherbe's calcifying cyst. Apropos of an unusual case in the middle ear. Histopathogenic value].

We report the case of a 54 years old man suffering with chronic otorrhea. The surgical procedure let us be surprised at a non specific cyst located in the "additus ad antrum", close to the incus but no damaging it. The result of the histologic examination was: Malherbe's calcifying cyst. After a background study of the publications concerning this type of tumor specially located in the skin, we can affirm this localisation in the middle ear cavity as exceptional. The cutaneous origin of this tumor and its vestigial type let us think about the possible persistence of amniotic fluid cellular content (AFCC) in the middle ear and its tumoral development in adult, explaining maybe partly the chronic otorrhea syndrome of this case.
