Periarticular malacoplakia.
Malacoplakia is a granulomatous process that occasionally affects the musculoskeletal system. It is thought to be caused by a dysfunction in mononuclear cells and their inability to lyse bacteria effectively. A strong correlation between this entity and immunosuppression has been noted. When a granulomatous mass is present in an immunosuppressed patient, the diagnosis of malacoplakia should be considered.
