The cell of origin for a neurilemmoma is the Schwann cell, which is derived from neurilemmoma: ( shwah-nō'mă ) A benign, encapsulated neoplasm in which the fundamental component is structurally identical to a syncytium of Schwann cells; the neoplastic cells proliferate within the endoneurium, and the perineurium forms the capsule. The neoplasm may originate from a peripheral or sympathetic nerve, or from various cranial The most common type is the neurilemmoma, which may cause diagnostic problems because of hypercellularity and the fact that - in contrast to its more common counterpart in the soft tissue - it is often unencapsulated. We encountered one case of neurilemmoma. Histology revealed uniform spindle cells arranged in loose stroma.
