Pigmented Melanotic Schwannoma of the Neck: Report of 2 Cases and Review of the Literature.

Abstract

Melanotic schwannoma is a rare tumor with indeterminate biologic behavior and varying treatment recommendations. We report 2 cases of pigmented melanotic schwannoma of the head and neck and perform literature review. The pathologic and immunohistochemical characteristics of melanotic schwannoma are reviewed. Two cases of melanotic schwannoma are presented. Both cases underwent surgical resection with one patient receiving adjuvant radiation therapy. Melanotic schwannoma is a rare nerve sheath tumor that is frequently mistaken for malignant melanoma. We describe 2 cases of pigmented melanotic schwannoma of the head and neck with different presentations and review the histopathological and immunohistochemical features.
