Idiopathic punctate necrosis of the phalanges of the feet.
Small areas of discrete radiolucency surrounded by well-defined margins of sclerosis are incidental asymptomatic findings in the proximal phalanges of the feet, usually in young males. Histologic examination of similar lesions discovered in the feet of cadavers shows fat necrosis. Although the etiology of these lesions is as yet unproven, musculoskeletal stress is suggested.
