[Importance of cytological study in the diagnosis of phyllode tumor, sarcoma and carcinosarcoma of the breast].

The paper deals with the results of application of clinical, cytologic and complex clinico-cytologic procedures of diagnosis of fibroadenoma phylloides mammae (160), sarcoma developing from libroadenoma phylloides (17), carcinosarcoma (5) and stromal or primary sarcoma (7). All the cases were treated at the Institute in 1960-1980. The difficulties involved in clinical diagnosis of these tumors are discussed. Correct clinical diagnosis was made only in 17% whereas benign and malignant tumors were identified in 94.7%. Cytological examination serves to improve the differential diagnosis between such neoplasms. Due to its application, the histological pattern of tumor was established in 30.6% and the benign or malignant nature of tumor--in 81.5%. When a complex clinico-cytologic examination was conducted diagnosis was improved in nearly half the cases (44.9%).
