title: Red grain botryomycosis due to Staphylococcus aureus--a novel case report.
abstract: Staphylococcus aureus and some other bacteria are known to cause botryomycosis. These bacteria are known to produce yellowish-white soft grains. Only Actinomadura pelletieri is known to produce red grains. We report here a case of an intensely inflammatory type of botryomycosis. A 35-year-old male labourer presented with swelling, redness and multiple sinuses on his foot, of eight months duration. The purulent discharge contained bright red coloured grains, 0.5 to 1 mm in size, which were round to oval in shape. Gram-positive cocci were demonstrated in crushed granules and tissue sections. Culture yielded pure and heavy growth of Staphylococcus aureus . He responded very well to cefazolin. There is no other report of such red grain botryomycosis due to Staphylococcus aureus , available in literature. This is first case report of its kind in world literature.
