Sonographic Findings for Posttraumatic Pacinian Neuroma: A Case Report

ABSTRACT

Pacinian neuroma is a rare tumor characterized by hypertrophy and hyperplasia of preexisting pacinian corpuscles. This tumor most frequently presents as a small superficial mass affecting the hands and feet, which produces localized sharp pain. The etiology is unknown, but local trauma has been postulated as an important factor. Here we report a case of posttraumatic pacinian neuroma in a 24-year-old woman who presented with severe local pain in the palm. The clinical features, and the sonographic and pathologic findings of posttraumatic pacinian neuroma are discussed.
