title: Atypical necrobiosis lipoidica of the face.
abstract: A 36-year-old healthy man with atypical necrobiosis lipoidica of the face is described. The lesions were annular with a raised erythematous palpable border. The centres were slightly depigmented and atrophic, without telangiectasia or hair loss. Histopathological changes revealed prominent giant cells in small groups without clear granuloma formation. They were located at all levels of the drmis between the collagen bundles.
