Schwannomas are benign tumors of neural crest origin that can arise from any nerve. Ancient Schwannomas are an exceedingly rare but benign variant characterized by degenerative changes on histopathology, often mimicking malignancy. Here, we report a case of a 45-year-old man presenting with a painful swelling in the left hand. Magnetic resonance imaging (MRI) suggested Schwannoma. Surgical excision revealed the tumor arising from a branch of the ulnar nerve. Histopathological examination confirmed the diagnosis of ancient Schwannoma through immunohistochemistry.
