[Systemic proliferating angioendotheliomatosis].

A 75-year-old female patient with neurological disturbances and numerous erythematous skin infiltrates is presented. Angioendotheliomatosis proliferans systematisata was diagnosed on histological detection of intravascular tumour cells in the cutaneous blood vessels. On immunohistochemistry and electron microscopy, the mononuclear tumour cells were identified as atypical B-lymphocytes. Our results provide further evidence that angioendotheliomatosis proliferans systematisata is a malignant angiotropic lymphoma with neurocutaneous manifestation.
