Calcinosis Cutis Circumscripta Of Knee-A Rare Presentation.

INTRODUCTION: Calcinosis circumscripta is a form of ectopic mineralization characterized by single or multiple cutaneous nodules containing calcium salts. Calcinosis cutis circumscripta is a very rare form of idiopathic calcinosis cutis arising in the second half oflife. It typically involves the extremities and is associated with prior trauma and scleroderma. We dealt with a very rare form of calcinosis cutis circumscripta in a healthy patient, for whom surgical excision revealed to be an effective and successful treatment. CASE PRESENTATION: 33-year-old male presented to OPD with swelling over the right knee joint. Clinically the swelling was adhered to skin, bony hard, tender, and movements of right knee were painful. The patient was investigated and once fit was taken for surgery. The patient was treated surgically by excising the swelling. CONCLUSION: Surgical excision is the mainstay of the treatment. Indications for surgical removal include pain, recurrent infection, ulceration, and functional impairment. Following excision, however, recurrence is common.
