Atrophic dermatofibroma.
Atrophic dermatofibroma, a newly proposed entity in recent times, is thought to be a specific variant of dermatofibroma. We report a typical case of atrophic dermatofibroma on the thigh of a 69-year-old female. The lesion consisted clinically of a light brown, intracutaneous nodule with a central crateriform depression, and histologically of fibrohistiocytic components in the thinning dermis. On elastica van Gieson stain, loss of elastic fibres and dense accumulation of elastic fibres around medium-sized vessels were observed in the lesion.
