Tumoral calcinosis is a rare ectopic extra-vascular calcification occurring around the joints. Deranged metabolic abnormality is the initial trigger for such calcification. We had a 28 year old female who had chronic swelling in both the hips for the past 24 months. On examination, bilateral, painless non-tender, firm lumps were observed in both the gluteal regions. X-ray of the local regions revealed bilateral large, lobulated, soft tissue masses that showed flocculent calcification which overlay the proximal third of femur. The patient was diagnosed to be a case of bilateral tumoral calcinosis and was managed successfully by excision and debulking surgery. We describe here this case of idiopathic calcinosis due to hyperphosphatemia considering its rare occurrence.
