[Dermatofibrosarcoma protuberans].

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.

Blastomogenic activity of p-hydroxyphenyllactic acid in mice.

Blastomogenic activity of p-hydroxyphenyllactic acid was established by prolonged s.c. administration into C57BL/6 and CC57BR mice. Phenyllactic acid was also tested and was not blastomogenic under the same conditions. The preparations in aqueous solutions were injected into the dorsal region twice weekly in 1.5-mg doses. The total dose per mouse was 42 mg p-hydroxyphenyllactic acid or 50 mg phenyllactic acid. The resorptive character and many forms of blastomogenic activity of p-hydroxphenyllactic acid were shown. It induced neoplasms of varied histogenesis (leukemias, adenomas, hepatomas, and tumors of the vascular tissue),including benign and malignant tumors and precancerous conditions of the urniary bladder.
