title: [Multinucleate cell angiohistiocytoma].
abstract: BACKGROUND
  Multinucleate cell angiohistiocytoma is a rare benign vascular proliferation. We report a case.
  
  
  METHODS
  A 75-year-old woman presented violaceous papules on the right thigh. Histological examination showed a proliferation of small blood vessels with multinucleated cells in the dermis and confirmed the diagnosis of multinucleate cell angiohistiocytoma.
  
  
  CONCLUSIONS
  Multinucleate cell angiohistiocytoma is a rare benign vascular tumor first described in 1985 often confused with Kaposi's sarcoma. Clinically it is characterized by violaceous papules on acral sites and face in elderly women. Histological examination shows an increased number of blood vessels together with mononucleated and multinucleated histiocyte-like cells in the dermis. Reviewing the literature we describe the main clinical and histopathologic features of this disorder.
