All of the following are TRUE regarding erythrocyanosis frigida, EXCEPT:

Erythrocyanosis frigid occurs exclusively in young females. Usually these people are obese with thick ankles and large amounts of subcutaneous fat. The etiology is believed to be ischemia of the area involved due to spasm of branches of posterior tibial and peroneal aeries. The vessels are abnormally sensitive hot and cold weather as in Raynaud's disease. The non healing ulcers formed due to the ischemia are called Bazin's ulcer. Ref: Manpal Millennium Edition, Page 52
