A RARE CASE REPORT ON ANCIENT SCHWANNOMA OF RIGHT LITTLE FINGER

Abstract

A 70-year-old woman had become aware of a mass on the dorsal aspect of the middle phalanx of her right little nger 9 years earlier. Her medical history was unremarkable, with no traumatic injury of the right little nger. Initial examination revealed a hard, immovable swelling of 15 × 10 mm on the dorsal aspect of the middle phalanx of the right little nger. No pain, sensory disturbance, or motor dysfunction was noted. The patient underwent FNAC at Adichunchanagiri Hospital and Research Centre and features were suggestive of benign spindle lesion/possibility of peripheral nerve sheath tumor. Total excision of the tumor was performed under block. Histopathological ndings revealed circumscribed benign tumor composed of hyper cellular and hypo cellular areas, hyper cellular area shows bro collagenous tissue, spindle cells in palisading arrangement, whereas hypo cellular area shows edema with thrombosed vessels, also hyalinisation and myxoid changes at places are observed. Based on these ndings, the patient was diagnosed as having ancient schwannoma. There was no evidence of infection, pain, complications such as recurrent tumor at 6 months postoperative.
