Metastatic seminoma of the temporal bone.
Temporal bone metastasis of classic testicular seminoma is extremely rare in the English literature. Except for a clinical case report of seminoma in the temporal bone, to our knowledge there is no temporal bone pathology report of secondary seminoma. In the left temporal bone of the present case, tumor cell infiltration was found in the external auditory canal, tympanic membrane, middle ear cavity, tympanic and mastoid mucosa, tensor tympani muscle, and so on.
