Botryomycosis. Some African cases.

Botryomycosis is a rare and chronic but readily treatable form of mycetoma. It is caused by a persistent bacterial infection and is distinguished by the formation of grains and multiple sinuses in the skin. The most usual cause is caused by Staphylococcus aureus. The authors' experience with four Transvaal cases is reported. In one case there was destruction of the skull and penetration of the cranial cavity by the botryomycotic process. Treatment with a range of common antistaphylococcal antibiotics led to astonishingly rapid recovery. Among the drugs used, cotrimoxazole was, perhaps, the most practical.
