title: [Control of the quality of tissue morphological diagnosis from the results of the Oncology.ru Pathology school].
abstract: Two-year experience of the Oncology.ru Pathology school showed typical errors in the morphological diagnosis of complex cancer diseases, which were made in 7-67% of the examined cases. Inaccuracies in formulating morphological conclusions were made in 5-71% of the examined cases. The highest frequency of erroneous answers (67%) was noted in vaginal myxoid fibroma. Errors were relatively less common (31-45%) while diagnosing carcinoma of the perspiratory and sebaceous glands, neurofibroma, and Abrikosov's tumor of the skin. The average frequency of erroneous answers was in the range of 12-21% in cases of gastrointestinal stromal tumor of the esophagus, breast carcinoma in situ, placental hemangioma, vaginal botroid rhabdomyosarcoma, and malignant fibrous histiocytoma of the skin. The least frequency (7-10%) of errors was recorded when gastrointestinal carcinoid tumors, urothelial cancer of the bladder, cylindroma, and melanoma of the skin, and gastric MALT lymphoma were diagnosed. Retrospective analysis of these errors can be a real impetus to self-education and have great benefits to improve specialists' professional skills. It is extremely necessary to use of various education forms, including informal trainings, for continuous professional improvement of pathologists.
