Abstract

Tumoral calcinosis is a very rare disease in which calcium deposit is accumulated on soft tissue around joints without specific metabolic disorder of calcium or predisposing illnesses. Its causes have not been revealed clearly, and the disease has been known to occur rarely among Asian patients. We report a case of a multiple giant tumoral calcinosis patient who complained of painful masses in the groin region as well as in both buttocks and sacral area. The patient was evaluated to differentiate with other causes and have been treated with surgical excision. We present this case with a review of literature.

  Figure 1 Plain radiograph of hip joint. Preoperative plain radiograph of hip joint is showing huge multinodular calcified mass in both hip, sacrum, buttock.

  Figure 2 Bone scan images show hot uptake of both hip, sacrum, and buttock.

  Figure 3 Pathologic findings. Microscopic image is showing mass of amorphous eosinophilic calcified materials, which is bordered by multinucleated macrophages, osteoclast like giant cells, fibroblast and chronic inflammatory elements, separated by dense fibrous tissue bands (H&E, ×400).

  Figure 4 Plain radiograph of hip joint after 2nd excision and biopsy. Postoperative plain radiograph of hip joint shows complete excision of calcific masses.
