Pacinian neuroma is an extremely rare feature, defined as hyperplasia or hypertrophy of Pacinian corpuscles. About half of Pacinian neuromas present with point tenderness. There have been a limited number of cases reported around the world. We observed a 45-year-old woman with an 8-month history of a tender whitish papule on her left thumb tip. Histopathologically, an enlarged hypertrophic Pacinian corpuscle in subcutaneous tissue, surrounded by numerous nerve fibers, was found. Herein, we report a case of Pacinian neuroma presenting as a tender papule on a fingertip that was clearly related to repetitive trauma at that site. This case shows that a meticulous history and histological examination can lead to an exact diagnosis and proper treatment. Keywords: Pacinian neuroma, repetitive trauma How
