Red discoloration of the sputum by clofazimine simulating haemoptysis--a case report.

A patient of lepromatous leprosy, who received a high dose of clofazimine as part of multidrug therapy, for chronic erythema nodosum leprosum (ENL) had frequent 'haemoptysis'. The haemoptysis was later found to be due to expectoration of clofazimine. This interesting, and perhaps first case of such an occurrence, is reported.
