X-ray logical study. Most patients underwent x-ray examination of the mammary glands (in 147 patients with leaf-shaped tumors and 39 with mammary sarcomas).

When analyzing the results of a survey of 147 patients (according to the data of G. Korzhenkova) with leaf-shaped tumors it turned out that the correct radiographic diagnosis was established only in 43 cases (29.3%).

The analysis of the observations made allowed us to distinguish two groups of tumors from the radiological position (in terms of the degree of complexity of diagnosis): formations up to 5 cm in diameter and more than 5 cm.

The least diagnostic difficulties are caused by identification of leaf-shaped tumors of large sizes. In 71 cases (48.3%), the neoplasm of the breast was larger than 5 cm, of which 37 cases (52%) were benign, 22 cases (31%) were intermediate, and 12 cases (17%) - malignant leaf-like tumors. Typical was the tumor in the form of a conglomerate of nodes with distinct hummocky contours - 63 cases (88.7%). A macroscopic study of the removed preparations made it possible to explain this phenomenon by alternating tumor nodes with cystic cavities that merge into a single conglomerate.

It is much more difficult to diagnose a small leaf-shaped tumor - up to 5 cm in diameter (76 patients, or 51.7%).

On mammograms, it usually has the form of an oval or rounded nodular formation with smooth, clear and only sometimes polycyclic contours; the structure of the tumor is uniform.

Differentiate these forms of leafy tumor with fibroadenoma and solitary cyst is very difficult, and often impossible. Of the 76 cases (51.7%) of leaf-shaped tumors with a size of up to 5 cm: 55 cases (72.3%) were benign leaf-like tumors, 16 cases (21%) - an intermediate variant, and 5 cases (6.6%) - malignant. Thus, at sizes up to 5 cm benign leaf-like tumors significantly prevail (p Keywords:.
