Calciphylaxis as a rare cause of a chronic wound in an 83-year-old woman

Abstract

Chronic wounds are common in elderly patients, and the majority of them are caused by vascular diseases, such as peripheral arterial occlusive disease (PAD) or chronic venous insufficiency. Because of typical signs, these diseases can be usually easily differentiated. However, 10% of chronic wounds are caused by specific rare diseases, such as vasculitis, specific infections, skin cancer, or calciphylaxis. Calciphylaxis is a rare cause of chronic wounds, and it is usually found in patients with end-stage renal disease. In this paper, we describe the case of an 83-year-old woman with a chronic ulcer of the lower leg caused by calciphylaxis.
