При первичном обращении в виду возраста, отсутствия онкологического анамнеза, небольшого размера новообразования, отсутствия ракового роста по данным биопсии, отсутствия клинических проявлений было рекомендовано динамическое наблюдение. В динамике через 6 месяцев выявлено увеличение размеров опухоли поджелудочной железы. После комплексного дообследования были выставлены показания к операции и проведена лапароскопическая спленосохранная дистальная резекция поджелудочной железы по типу Warshaw. Послеоперационное патогистологическое исследование: муцинозная кистозная опухоль поджелудочной железы с микрофокусами high grade дисплазии эпителия (Сa in situ). Сделан вывод о том, что онконастороженный подход при кистозных опухолях поджелудочной железы должен быть в том числе у лиц молодого возраста.</p></abstract><trans-abstract xml:lang="en"><p>This paper presents a clinical case of treating a 22-year-old female patient with a malignant cystic tumor of the pancreas. At the initial consultation, due to her age, no oncological history, small size of the tumor, no cancerous growth according to biopsy data, and no clinical manifestations, dynamic observation was recommended. In dynamics, after 6 months, an increase in the size of the pancreatic tumor was detected. After a comprehensive additional examination, indications for surgery were established and laparoscopic spleen-preserving distal resection of the pancreas according to the Warshaw type was performed. Postoperative pathohistological examination: mucinous cystic tumor of the pancreas with high-grade microfoci of epithelial dysplasia (Ca in situ). It is concluded that an  oncoguarded approach to cystic tumors of the pancreas should be used,  including in young people.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кистозная опухоль поджелудочной железы</kwd><kwd>рак поджелудочной железы</kwd><kwd>дистальная резекция поджелудочной железы</kwd><kwd>кистозный рак</kwd><kwd>малигнизация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cystic tumor of the pancreas</kwd><kwd>pancreatic cancer</kwd><kwd>distal resection of the pancreas Warshaw</kwd><kwd>cystic cancer</kwd><kwd>malignancy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Zerboni G, Signoretti M, Crippa S, Falconi M, Arcidiacono PG, Capurso G.
