Pernio of the hips in young girls wearing tight-fitting jeans with a low waistband.

Sir, In 1980 Beacham et al. (1) described equestrian cold panniculitis in overweight young women wearing tightfitting uninsulated riding trousers. They developed reddish tender plaques on the thighs due to prolonged cold exposure during equestrian activities in the winter. Cold panniculitis and pernio (chilblains), which is a relatively mild form of cold injury, has also been described in children wearing cold wet shoes or boots (2) and in mountaineers after wading across rivers (3). It is especially the fat-rich hip and lateral thigh regions of young women that are affected. The recent fashion among young women for tight jeans with a low waistband, exposing the upper part of the hip region to cold may result in hip pernio, as described in the following cases.
