A rare case of ceruminous tumor of the cerebellopontine angle.
In this case report we describe the development in the cerebellopontine angle of a very rare tumor, ceruminous adenoma. In the few cases described in the literature this tumor occurred in the external acoustic meatus. In four cases it developed in the cerebellopontine angle by infiltration of the petrous bone or by subcutaneous spread. In the present case no connection was found between the cerebellopontine angle and the external acoustic meatus. The most likely pathogenetic hypothesis in this case is that of a tumor of dysembryogenetic origin.
