A case of traumatic neuroma

Neuromas are hyperplasia of axons and associated nerve sheath cells. Cutaneous neuromas are uncommon. Three kinds of true neuromas exist in the skin and mucous membranes: traumatic neuromas, solitary palisaded encapsulated neuromas, and multiple mucosal neuromas. Traumatic neuromas are usually solitary, skin-colored or pink, firm papules or nodules at the sites of scars following local trauma. A 2-year-old male patient presented a solitary rice grain sized, skin-colored painful and tender polypoid papule on the left 2nd finger. The lesion was superimposed on a small linear scar. The patient had taken a trauma by a broken piece of glass about one month before the development of the neuroma. We report a case of traumatic neuroma with a review of the literature.
