Catfish spine envenomation: a case of delayed presentation.

Catfish spine envenomations can result in debilitating hand problems. Virulent bacteria may be introduced through a puncture wound. An offending organism may be difficult to culture, and a foreign body may be missed unless there is a high index of suspicion. The majority of cases present early and symptoms resolve within 3 months. We report a markedly delayed presentation and treatment of a catfish "finning" injury that resulted in chronic tenosynovitis to the hand. A review of the literature and current treatment recommendations are provided.
