[Cytologic diagnosis of non-organ neoplasms in the small pelvis]

Puncture biopsy specimens from 165 patients, 93 of these children, were examined to elucidate the potentialities and specific features of the diagnosis of inorganic neoplasms in the small pelvis. Cytologic diagnosis has proved to be a rational and sufficiently informative method, permitting a correct recognition of the process type in 83.6 percent of cases. Malignant tumors were correctly diagnosed in 94.1 percent of cases, benign and inflammatory processes in 45.6 percent. In the children teratoblastomas, neuroblastomas, and unclassified sarcomas predominated.
