A Rare Incidence of Necrotizing Lesion of the Upper Arm Due to Pentazocine Injection Abuse: A Case Report

A patient with a history of treated pain with intravenous drugs comes at high risk for drug abuse. Administration of intravenous pentazocine continuously for a long time in the same location affected the skin tissue. Pentazocine misuse is frequent among patients with chronic disease conditions and the easy availability of pentazocine injection can easily lead to significant consequences. We present a unique case of pentazocine misuse resulting in significant skin necrosis. We present a case of a 48-year-old male with a complaint of pain and wound with lesions over the arm due to the regular self-administered pentazocine in the same location. The therapeutic intervention given in this case is an opiate agonist to control the dependence on pentazocine.
