Pyomyositis in a renal transplant patient with Kyrle's disease.

Pyomyositis, an endemic disease of tropical origin, is increasingly reported in temperate zones, especially in patients with diabetes mellitus and in the immunocompromised. A 28-year-old renal transplant recipient presented with perforating skin lesions (Kyrle's disease), thigh pain, and swelling associated with fever. A gallium scan of the thigh led to surgical exploration and a diagnosis of pyomyositis. To our knowledge, the association of Kyrle's disease with pyomyositis has not been reported before. The significance of this combination of conditions in our patient remains unexplained.
