Finger Nerve Sheath Myxoma: A Rare Case Report

Abstract

Introduction: Nerve sheath myxoma (NSM) is a rare benign neoplasm of nerve sheath origin with Schwann cell differentiation. NSM and neurothekeoma were considered one single phenomenon in the past. Case Presentation: A 28-year-old woman presented to our hospital clinic with pain and a fixed firm mass in the proximal phalanx of the right second finger. Excisional biopsy was performed and histological examination revealed NSM. Conclusions: Based on the findings, NSM should be considered in the differential diagnosis of firm and tender masses in the upper extremities of young adults.
