Pacinian Corpuscles Neuroma. An Exceptional Cause of Pain in the Hand.

Pacinian corpuscles are rapidly adapting mechanoreceptors mainly distributed in the dermis of the fingers and palm of the hand. A neuroma of the Pacinian corpuscle is a rare and extremely painful condition with a few cases reported in the literature, most of them, associated with local or repetitive trauma. We present a 71-year-old man with history of pain and swelling on his left index without history of previous trauma initially diagnosed as tenosynovitis resistant to conservative treatment in which we observed, directly in the subcutaneous plane, spherical, gray and in clusters lesions closer to the collateral nerve which were described by the pathological study as neuroma of the Pacinian corpuscles.
