Talc lung in a drug abuser.

We report a case of intravenous talcosis in a 36 year old woman. Although she initially denied drug abuse clinical suspicion was aroused by the finding of obliterated peripheral veins, a pleural rub and a peripheral nodular lesion on chest x-ray. Diagnosis of intravenous talcosis was confirmed by finding birefringent particles on transbronchial biopsy. Confronted with this evidence the patient admitted long-standing drug abuse, including intravenous injection of crushed methadone tablets which contain talc filler.
