Cutaneous malakoplakia. Report of a case.

A case of cutaneous malakoplakia in a 44-year-old women under immunosuppressive therapy after renal transplantation for nephrosclerosis is reported. A nodular lesion with inflammatory signs appeared on her right buttock. Histopathology showed a dermal infiltrate with histiocytes containing Michaelis-Gutmann bodies. Electron microscopy showed Michaelis-Gutmann bodies with concentric laminar structure ('target' appearance). Tissue culture revealed Escherichia coli growth. Lesions recurred on surrounding skin and left buttock after excision. Clofazimine treatment resulted in total remission.
