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 1 st 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 1 st 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.
