A Case of Traumatic Neuroma Probably Originated from Dorsal Digital Nerve / 대한피부과학회지

ABSTRACT

Neuromas are hyperplasia of axons and associated nerve sheath cells. Cutaneous neuromas are rare. Neuromas can be classified into three types traumatic neuromas, solitary palisaded encapsulated neuromas, and multiple mucosal neuromas. Traumatic neuromas are tangles of neural fibers and connective tissue that develop following nerve injury. These usually present as a solitary, skin colored or pinkish, slowly growing, palpable and painful firm papule or nodule. A 15-year-old female patient presented a solitary 1.0x0.5 cm sized, pinkish palpable well-demarcated firm subcutaneous nodule on the right third proximal interphalangeal joint. We herein report a case of traumatic neuroma which probably originated from the dorsal digital nerve.
