title: Pentazocine-induced leg ulcers and fibrous papules.
abstract: We herein describe a case of 55-year-old farmer, who presented with chronic non-healing ulcers over both shins of 4 years duration. Intravenous drug abuse was suspected due to inability to find any venous access and all peripheral veins being found thickened and fibrosed. There were multiple atrophic scars in linear distribution in all limbs as well as in both groins. In addition there were multiple discrete fibrous papules in linear distribution on both hands, which were more obvious on the left side. The patient denied abusing intravenous drugs. However, his relatives confirmed that he abused pentazocine for almost one year before his chronic pain in abdomen was treated by appendicectomy. With subsequent counseling, it was found that he continued to abuse pentazocine at times even after surgery leading to the non-healing of ulcers.
