Pulmonary mucoraceous fungal ball.

A case of opportunistic pulmonary infection in the form of fungal ball produced by the family of mucoraceae in the class of phycomycetes having nonseptate hyphae (cellophane tubules) with haphazard branching in a post-tubercular immunocompetent patient is described. Clinical course was chronic with right upper lobe cavity invaded by fungi of mucor species, pathology was granuloma with blood vessel thrombosis, and a fungus ball. The host had no associated predisposing diseases. Segmental resectional surgery of the right upper lobe along with removal of fungus ball under the coverage of modified dose of amphotericin B was performed. Literature scanning revealed rarity of mucormycosis in immunocompetent host.
