Botryomycosis--a series of six integumentary or visceral cases from India.

Botryomycosis is characterized by a chronic suppurative lesion with distinctive fungus-like grains that resemble the sulphur granules of actinomycosis. Both integumentary and visceral forms of the disease are recognized. The visceral involvement occurs predominantly in the lungs. Botryomycosis may develop in apparently healthy individuals as well as the immunologically compromised. Six cases of botryomycosis, affecting various sites in the bodies of immunocompetent individuals, are described. In each of the six cases, the initial clinical diagnosis was of an abscess or malignancy.
