[Differential diagnosis of malignant forms of hormonally-active tumors of the ovary].

Case histories of 427 patients with main histotypes of hormone-producing tumors of the ovaries (201--theca-cell, 177--granulosa-cell, 28--mixed theca-granulosa-cell and 21--virilizing) were analyzed. The problem of differential diagnosis of malignant forms of these tumors by methods of clinical examination was studied. Major statistically significant clinical signs of malignancy of hormone-producing tumors of the ovaries--extension of abdomen and abdominal pain, relatively short duration of case history, bilateral lesions, large size of sessile tuberculous tumors, high level of ascites, especially hemorrhagic one, and comparatively young age of patients--were established.
