ABSTRACT
Pacinian neuroma is a rare skin disease characterized by hyperplasia or hypertrophy of the Vater-Pacini corpuscles which are responsible for the appreciation of deep pressure and vibration. It usually affects the volar aspects of the fingers in middle-aged adults and it produces severe pain and tenderness on the affected skins. About half of previously reported cases revealed the association with precipitating factors such as local trauma, but underlying mechanisms are not established. Two patients presented with a several months history of solitary pale-colored papule on the tip of finger. The patients reported a severe tenderness on the lesion with a history of repetitive trauma. The histopathologic examination from the lesions showed increased number of onion-like stratified structures around nerve fibers, compared to the usual density of pacinian corpuscles (3~5/cm2). The histopathological features were consistent with pacinian neuroma. The symptoms of the patients disappeared soon after the surgery. Herein, we present two patients with pacinian neuroma on the finger, and we also propose that pacinian neuroma should be considered for the differential diagnosis of tender papule on the digit.
