Hyperparathyroidism Tumoral calcinosis: A case report

Abstract

Tumoral calcinosis (TC) is a rare locally aggressive lesion characterised by extra-articular soft tissue deposition of the calcium phosphate around large joints & small joints. The exact aetiology is not known. A 11–year–old female presented with a painful progressive swelling around the medial aspect of 1st metatarsal right foot over a 6–month duration. Routine laboratory results showed a normal haemogram, and normal calcium and high phosphate levels & para thyroid level. Imaging showed a soft tissue calcified mass around 1st metatarsal medial aspect of right foot. The cut surface of the excised mass showed myxoid material with areas of calcification. On microscopy, there were typical features of Tumoral calcinosis.
