title: [Dermatofibrosarcoma protuberans].
abstract: Observations were conducted on 26 patients with protruding dermatofibrosarcoma of the skin. Histological and histochemical characteristics, as well as the mitotic regimen of these tumours, were investigated. Protruding dermatofibrosarcoma is a fibroblastic tumour characterized by a slow growth, usually a big size, persistent multiple reoccurrence, late metastases into the lymphatic nodes and lungs. No regularities concerning periods and frequency of developing of reoccurrences could be established. Clinico-anatomical collations failed to show correlation between the mitotic activity of dermatofibrosarcomas and the degree of their malignancy and rate of growth of the tumour.
