Necrobiosis lipoidica--involvement of atypical sites.


Necrobiosis lipoidica (NL) has distinctive clinical and histological appearances. The legs are the commonest site of involvement, and 85% of cases involve the legs exclusively. We describe a patient in whom NL did not involve the legs, but was found to occur on unusual areas: the back and nipple. This is possibly the first report of NL affecting the nipple.
