Akın İE, Özay M. A Rare Case Report of Penile Necrosis Successfully Treated With Early Hyperbaric

Oxygen Treatment. Undersea Hyperb Med. 2026 Second Quarter; 53(2):291-294.

Introduction: Warfarin is a widely used oral anticoagulant for the treatment of thromboembolic

disorders. Warfarin-induced skin necrosis (WISN), a serious but rare complication, typically affects the

breasts, hips, and abdomen. Penile necrosis, however, has been reported only in exceptionally rare cases.

Case Report: In this report, we present the successful outcome of early hyperbaric oxygen treatment

(HBO2) in a patient who developed glans penis necrosis during warfarin treatment and was subsequently

diagnosed with protein C deficiency. The patient underwent nine HBO2 sessions initiated early in the

disease course and achieved full recovery without tissue loss.

Discussion: To our knowledge, this is the first reported case in which HBO2 was used as part of a

combination treatment for penile necrosis in a patient with protein C deficiency. Hyperbaric oxygen

treatment may represent an effective therapeutic option in rare cases of warfarin-associated penile

necrosis.
