A rare case of pseudoglandular schwannoma

Öz

A pseudoglandular schwannoma is a rare benign tumor. Controversy in the literature regarding the histogenesis of pseudoglandular schwannoma exists. Histological features of pseudoglandular schwannomas are different than those found in classical schwannomas. A patient with pseudoglandular schwannomas has a good prognosis, and no cases of recurrence have been reported in the literature.
