Abstract
- A sixty-eight-year-old female presented with suddenly developed pain in the left knee joint. On the first visit, there was severe tenderness on the anterolateral aspect of the knee joint with active flexion and extension limited by pain. Radiographs revealed multiple round calcific masses in the anterolateral aspect of the knee joint. Under the impression of intraarticular lesions, we performed arthroscopic examination of the knee joint, which revealed no intraarticular pathology. The masses were found in the extracapsular soft tissue and we performed excisional biopsy of the masses completely. The masses were confirmed as tumoral calcinosis by histopathologic examination. It rarely occurs around the knee joint and is usually asymptomatic. Idiopathic tumoral calcinosis with acute symptoms must be differentiated from other pathologic conditions such as gout or infection. The clinical manifestation of this case was opposed to the previous reports. So we report a rare case of idiopathic tumoral calcinosis of the knee joint with acute symptoms.
