N2 - A malignant epithelioid schwannoma was diagnosed affecting the trigeminal nerve of an 11-year-old dog. Neurologic abnormalities included an altered mental status, ataxia, left head tilt, postural reaction deficits of all four limbs, a pronounced left masticatory muscle atrophy, and absent left facial sensation. Histologically, a densely arranged epithelioid population with a very high mitotic index was surrounded by a spindle-shaped cell proliferation characteristic of schwannomas. Both cell populations stained positively for vimentin, but only spindle cells were occassionally positive for S-100 protein. The histologic and immunohistochemical features of this tumor were consistent with those found in human epithelioid schwannomas.
