Tuberculous Pyomyositis in a Renal Transplant Patient / 대한신장학회잡지

ABSTRACT

Tuberculosis infection of skeletal muscle is rare, even in countries where tuberculosis is relatively prevalent. Because tuberculosis of muscle is usually secondary to underlying tuberculosis of the bone or adjacent joint, isolated tuberculosis of skeletal muscle is very rare. Moreover, tuberculosis pyomysitis shows nonspecific symptoms even in immuno-compromised hosts. Recently we experienced an isolated tuberculosis pyomysitis in renal allograft recipient and report here. A 57-year-old woman presented with pain and edema on right calf area. Sonographic imaging of right calf muscle showed large elongated fluid collection. Operative debridement was done and the histopathology of calf muscle showed granulomas surrounded by Langhans' giant cells. We diagnosed her as tuberculous polymyositis combining the data of histology and positive result of polymerase chain reaction for mycobacterium tuberculosis. We treated her with the anti-tuberculosis medication. After surgical debridement and medical management, calf muscle tuberculous polymyositis showed fair improvement.
