Necrobiosis is an uncommon and unsightly blemish of the skin which chiefly affects diabetic women. It is unrelated to microvascular complications. The shin is the most common site. The lesions show rather atrophic skin at the centre with obviously dilated capillaries (telangiectasis) and a slightly raised pinkish rim; ulceration sometimes occurs. The lesions are indolent and rarely resolve. There is no effective treatment although steroid applications and even injection have been attempted.
