Rarely the tumor develops in the perineal area and quite rarely is large. For the Leser-Trelat syndrome these tumors is a marker of a malignant disease even before the symptoms are appeared, as well as a manifestation of the paraneoplastic process. In our case report, a giant perianal seborrheic keratoma was the reason for the clinical examination of the patient and stomach cancer was detected. As a result, we demonstrated a successful experience of surgical treatment of seborrheic keratoma of the perianal area and determined an algorithm for the treatment of stomach cancer.</p></abstract><trans-abstract xml:lang="ru"><p>Себорейный кератоз - самая распространенная Доброкачественная опухоль эпидермиса, однако область промежности поражается достаточно редко. Значительно реже себорейные кератомы этих локализаций достигают гигантских размеров. В некоторых случаях данные опухоли могут служить маркером злокачественного заболевания еще до появления симптомов его развития и быть проявлением паранеопластического процесса. Одним из таких заболеваний является синдром Лезера-Трела. В представленном клиническом наблюдении гигантская перианальная себорейная кератома стала причиной обследования пациента, во время которого был выявлен рак желудка. В результате нами продемонстрирован удачный опыт хирургического лечения «симптомной» опухоли перианальной области и определен алгоритм лечения рака желудка.</p></trans-abstract><kwd-group xml:lang="en"><kwd>seborrheic keratosis</kwd><kwd>Leser-Trelat syndrome</kwd><kwd>perianal zone tumor</kwd><kwd>benign skin tumors</kwd><kwd>giant tumors</kwd><kwd>V-Y plastic surgery</kwd><kwd>gastric adenocarcinoma</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>себорейный кератоз</kwd><kwd>синдром Лезера-Трела</kwd><kwd>опухоль перианальной зоны</kwd><kwd>доброкачественные опухоли кожи</kwd><kwd>гигантские опухоли</kwd><kwd>V-Y-пластика</kwd><kwd>аденокарцинома желудка</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Sudhakar N., Venkatesan S., Mohanasundari P.S. et al.
