Removal of corns by punch incision: a retrospective analysis of 15 patients.

BACKGROUND: Hard corns are firm, small, dome-shaped papules with translucent central cores, which occur on the palmoplantar region of toes and hands due to repeated trauma. Medical management of hard corns is difficult and sometimes requires surgical excision. Punch incision is a technique which is performed using a circular blade or trephine attached to a pencil-like handle. AIM: We hypothesized that it might serve as an alternative method to surgical excision in the treatment of recalcitrant corns and performed the technique to treat 17 corns in 15 patients. The present study aimed to review these 15 patients retrospectively and evaluate the effectiveness of punch incision. METHOD: A total of 15 patients with recalcitrant corns were treated using punch incision between April 2011 and December 2012 and were evaluated by photographs and patient satisfaction questionnaires. RESULTS: Out of the 17 corns, 3 corns persisted after punch incision and the patients were referred to the orthopedic clinic for further treatment; 2 of the 17 corns partially responded and required additional topical treatment; and 12 of the 17 corns responded completely to punch incision. CONCLUSION: Punch incision is a simple and effective technique for the treatment of small corns on the palms and soles.
