title: [Histiocytofibroma. Spontaneous regression, leaving skin atrophy].
abstract: Three cases of histiocytoma with atypical course are described by the authors. Two of them dissappeared completely or almost completely leaving a scar where some remnants of the original tumor were present. In the third patient the tumor grew deeply in the dermis leaving the same atrophic scaring on the surface. By palpation the original tumor was also detectable.
