Two Cases of Pacinian Neuroma on the Finger / 대한피부과학회지

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.

Pacinian Neuroma on the Tips of Fingers / 대한피부과학회지

Pacinian neuroma, also known as hyperplasia and/or hypertrophy of pacinian corpuscles is a rare skin condition usually occurring in the hand. Although it is known to cause pain and tenderness on the affected skin, asymptomatic cases have also been reported. We report a 46-year-old male monk who presented with asymptomatic skin lesions of paler color than the adjacent normal skin on the tips of the fingers of both hands. The 3 mm punch biopsy conducted on the lesion showed an increased number of onion bulb-like structures with a nerve fiber in each center. The patient was diagnosed with pacinian neuroma and has been under regular follow up without treatment.

Sonographic Findings for Posttraumatic Pacinian Neuroma: A Case Report

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.
