verrucous carcinoma: a temporal bone histopathology report.

Only nine
cases of primary verrucous carcinoma of the temporal bone have
been reported in the English literature. We describe
histopathologic findings in a 78-year-old man dying of
intracranial complications of primary verrucous carcinoma of the
external auditory canal. Following autopsy the temporal bone was
prepared for light microscopic examination. The temporal bone was
serially sectioned horizontally after fixation, decalcification,
and embedding, and each 10th section was stained with hematoxylin
and eosin and examined by light microscopy. The carcinoma
originated from the external auditory canal, infiltrating the
mastoid cavity, the middle ear, tissue adjacent to the internal
carotid artery, and the posterior cranial fossa, where it invaded
the right cerebellum and produced an abscess. The labyrinth and
internal auditory canal were not infiltrated. Metastasis to lymph
nodes or distant sites was not identified. In the present case,
the verrucous carcinoma originating from the external auditory
canal extended into the posterior cranial fossa, while it did not
invade the membranous labyrinth.

The
apparent rarity of verrucous carcinomas of the ear is reflected by
the fact that only three well-documented cases have previously
appeared in the literature. However, in other instances the
diagnosis of verrucous carcinoma may have been missed because of
the unfamiliarity of many clinicians and pathologists with the
morphologic characteristics of these lesions. We describe the
first case of a verrucous carcinoma confined to the external
auditory canal in which a positive diagnosis was only made
histologically after local recurrence of what was initially
diagnosed as a senile keratosis. The difficulties inherent in
diagnosing this lesion and the necessity of close cooperation
between the surgeon and pathologist if a diagnostic error is to be
avoided are emphasized. Careful follow-up of all warty lesions of
the external auditory canal and middle ear cleft is recommended.

A case report
of verrucous carcinoma in the ear of a patient subject to
persistent discharge from that ear for more than 30 years is
presented. The histology conformed to that in Ackerman's classic
description and a literature search revealed that this is only the
second case of this disease reported. The patient was treated
surgically followed by radiotherapy and was well 18 months later.
