title: Calcinosis cutis of the fingertip associated with Raynaud's phenomenon.
abstract: Cutaneous calcification may be divided into four major categories: (i) dystrophic; (ii) metastatic; (iii) idiopathic; and (iv) iatrogenic. Dystrophic calcification is the most common type of calcinosis cutis and is associated with a variety of diseases. It most notably occurs in connective tissue diseases. Diffuse and limited cutaneous systemic sclerosis is an example of connective tissue diseases that frequently show calcinosis. We experienced a case of fingertip calcinosis cutis associated with Raynaud's phenomenon. The patient had no previous trauma, skin lesion or systemic connective tissue disease. We propose that calcinosis cutis of the fingertip may result from chronic ischemic injury caused by Raynaud's phenomenon.
