Schwannoma (also known as neurilemmoma, neurolemmoma, neurinoma, perineural fibroblastoma, peripheral glioma, and peripheral nerve sheath tumor) is a slow-growing, benign neoplasm derived from Schwann cells, which are sheath cells that cover myelinated nerve fibers The presented case was of schwannoma in a 20-year-old male patient, who presented with painless swelling at the left side angle of the mandible. Clinically, no symptoms other than facial deformity were noted. Panoramic radiograph showed radiolucency presenting as secondary erosion at left angle of mandible region. Fine needle aspiration cytology suggested cytomorphology of benign spindle cell lesion, which was then confirmed histologically as nerve sheath tumor. It was difficult to diagnose the condition clinically due to the rare clinical presentation of the peripheral nerve sheath tumor. The lesion was completely excised. Postoperative follow-up of one year was taken without any recurrence. We attempt to present the versatility of presentation of such tumor and its effect on adjacent bone. Also, we found out that fine needle aspiration cytology can play a significant role in diagnosing clinically perplexing presentations of rare tumors.
