A 34-year-old white male prisoner with a history of dyspnea admitted to intravenous self-injection of "blue-velvet"—dissolved tripelennamine (Pyribenzamine®) tablets with and without narcotics. Serial chest X rays suggested progressive pulmonary fibrosis. Pulmonary function showed a restrictive type of disease pattern. Findings in cardiac catheterization were normal. Lung biopsy confirmed the diagnosis of pulmonary angiothrombosis caused by talc granulomata.
