A Pacinian hyperplasia of the foot.

Author information

  • 1Laboratory Pathology, Centre Hospitalier, Tulle, France.


A case of Pacinian hyperplasia of the right great toe is reported. Pacinian hyperplasia is a rare benign and recently recognized painful lesion composed of an excess of well formed or hyperplastic Pacinian corpuscules, normaly involved in sensory innervation. This lesion that is usually observed in the hand, must be distinguished from nerve tumors harboring onion-bulb structure which are not true well formed Pacinian corpuscules and from Morton neuroma. Pacinian hyperplasia is considered a reactive lesion and not a true neoplasm. To our knowledge, this case is the first described in the foot.
