cellular schwannoma of the palate simulating as malignant peripheral nerve sheath tumor: a diagnostic marathon

Schwannomas are considered benign soft tissue tumors that originate from schwann cells. oral schwannomas are rare and account for only 1% of all schwannomas. cellularschwannoma (cs) is a rare histological variant of schwannoma, characterized by high cellularity and cellular atypia. we present a case of localized growth of palatal mucosa that imitated the features of malignant peripheral nerve sheath tumor (mpnst) on histopathological examination; it was differentiated from mpnst by the correlation of clinical, histopathological, and immunohistochemical features.
