[Fine needle puncture of mesenchymal malignant growths of the mammary gland].

From 1967 to 1978 the author made 612 fine needle biopsies of the mamma (415 benignant, 197 malignant cases). Among malignant cases there were 11 primary (2 fusocellular, 1 rotundocellular sarcomas, 1 chondromyxosarcoma, 1 leiomyosarcoma, 1 melanoblastoma, 1 angiosarcoma, 4 malignant cystosarcomas phylloides) and 4 metastatic (1 rotundocellular, 1 reticulocellular, 2 melanoblastomas) sarcomas. The author gives a detailed report on cytomorphology, histology and diagnostical problems of mesenchymal malignomas. He thinks the practical value of fine needle biopsy important in the preoperative diagnostics of sarcomas in the mamma. On the basis of his experiences obtained during years, he considers it undangerous and recommends its daily use in practice.
