Cellular schwannoma is a relatively rare variation. Cellular schwannoma is nearly exclusively made up of a fascicular proliferation of well-differentiated Schwann cells that are cytologically bland, missing Verocay bodies, and just slightly exhibiting Antoni B pattern growth (10% of the tumor area).
Antoni A area of schwannoma with Verocay bodies (one annotated by circle) Verocay bodies were first described by Uruguayan neuro-pathologist José Juan Verocay in 1910. It is a required histopathological finding for diagnosing schwannomas (tumors of Schwann cells).
