The paper discusses a case of making an erroneous preoperative diagnosis in a spleen mass: the instrumental study findings determined the presence of multiple cysts. The latter among all the neoplasms of this organ are the most common and are represented by a variety of forms, subdivided by origin, histogenesis and content features. According to some classifications, cysts are classified as tumors or tumor-like diseases, other sources classify them as non-tumor formations of the spleen. It is not often possible to fully exclude the parasitic origin of the cyst before the morphological study of the removed organ. Surgeons of the Voronezh Regional Clinical Hospital No. 1 encountered this problem during the treatment of a 34-year-old patient with the spleen neoplasm. A diagnosis of lymphangioma was made based on surgical treatment and pathomorphological findings. The analysis of this clinical case demonstrates relevance of splenectomy both as a method of final diagnosis and as the final stage of treatment for benign tumors; it allows avoiding misdiagnosis in case of a malignant tumor.</p></abstract><trans-abstract xml:lang="ru"><p>Дифференциальная диагностика объемных новообразований селезенки, несмотря на хорошую визуализацию при ультразвуковом исследовании, компьютерной и магнитно-резонансной томографии брюшной полости, вызывает трудности в следствие отсутствии единой классификации, крайне редкой встречаемости части опухолей и трудности дооперационной морфологической идентификации. В статье описан случай постановки ошибочного предоперационного диагноза при объемном образовании селезенки: данные инструментальных исследований определили наличие множественных кист. Последние среди всех новообразований данного органа встречаются наиболее часто и представлены многообразием форм, подразделяясь по происхождению, гистогенезу и особенностям содержимого. Согласно некоторым классификациям кисты причисляют к категории опухолей или опухолеподобных заболеваний, другие источники относят их к неопухолевым образованиям селезенки. Зачастую не представляется возможным до морфологического исследования удаленного органа в полной мере исключить паразитарную природу кисты. С этой проблемой и столкнулись хирурги Воронежской областной клинической больницы №1 в ходе лечения пациентки 34 лет с новообразованием селезенки. В результате хирургического лечения и патоморфологического заключения поставлен диагноз: лимфангиома. Анализ данного клинического случая показывает оправданность спленэктомии и как способа заключительной диагностики, и как окончательного этапа лечения при доброкачественных образованиях и позволит не пропустить злокачественную опухоль.</p></trans-abstract><kwd-group xml:lang="en"><kwd>spleen, diagnosis</kwd><kwd>tumor and non-tumor formations</kwd><kwd>splenectomy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>селезенка</kwd><kwd>диагностика</kwd><kwd>опухолевые и неопухолевые образования</kwd><kwd>спленэктомия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Stepanova YuA, Goncharov AB, Zhao AV.
