However, even more rarely, they have clinical manifestations at patient’s early age and so, can be silent for a long time.</p> <p><bold>CLINICAL CASE DESCRIPTION:</bold><italic> </italic>The article describes a rare clinical observation — a giant dermoid cyst in the retrorectal space in a 17-year-old girl. The child had a tendency to constipation from her early childhood. Menses started at age 13, painful. During the last year, disorders in her menstrual cycle were noticed. The girl was examined by a gynecologist. Ultrasound examination revealed a cystic formation in the pelvic cavity up to 9 cm in diameter. Non-malignant nature of the process was confirmed by: normal level of cancer markers (α-fetoprotein, β-human chorionic gonadotropin), single node, clearly defined formation capsule, homogeneous nature of its contents, no invasive growth and lesions in the regional lymph nodes. Magnetic resonance imaging with intravenous contrasting defined a true relationship of the cystic formation with other organs and structures of the pelvic cavity. The cystic formation caused deformation of the cervix, vagina, and rectum. The obtained findings allowed to plan surgical intervention correctly. Surgical access-transverse in the coccyx projection up to 10 cm long. The cystic formation was a thin-walled connective tissue capsule with a yellowish content. Due to very large cyst dimensions, first it was opened in a limited area and emptied. Then the capsule was isolated and completely removed. The cyst intimately adhere to rectum, vagina, and cervix walls. Histological conclusion: "Capsule of a dermoid cyst with hemorrhages". The postoperative period was smooth. The patient recovered, all disease manifestations disappeared. She was discharged home in a satisfactory state. Follow-up visits were in 6 and 12 months after surgery. No evidence of possible relapse.</p> <p><bold>CONCLUSION:</bold> There are only few descriptions of such cases in the available literature. Ultrasound and MRI examinations allowed to have a full picture of dermoid cyst position and its connection with other pelvic organs due to which surgeons could develop a correct plan for surgical intervention.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Дермоидные кисты пресакральной области и ретроректального пространства у детей встречаются относительно редко. Однако ещё реже в детской хирургической практике они не имеют клинических проявлений в раннем возрасте и остаются незамеченными в течение продолжительного времени.</p> <p><bold>Описание клинического случая.</bold> В статье приведено описание редкого клинического наблюдения гигантской дермоидной кисты ретроректального пространства у девочки 17 лет. С раннего детства у ребёнка отмечалась склонность к запорам. Менструации с 13 лет, болезненные. В течение последнего года отмечалось нарушение менструального цикла. Девочка осмотрена гинекологом. В ходе ультразвукового исследования выявлено кистозное образование полости малого таза до 9 см в диаметре. В пользу доброкачественности процесса свидетельствовали: нормальный уровень онкомаркеров (α-фетопротеин, β-хорионический гонадотропин), наличие единичного узла, чётко выраженная капсула образования, гомогенный характер содержимого, отсутствие инвазивного роста и поражения регионарных лимфатических узлов. Магнитно-резонансная томография с внутривенным контрастированием позволила установить взаиморасположение кистозного образования с органами и структурами полости таза. Кистозное образование вызывало деформацию шейки матки, влагалища и прямой кишки. Благодаря полученным данным спланировано оперативное вмешательство. Оперативный доступ — поперечный в проекции копчика длиной до 10 см. Образование представлено тонкостенной соединительнотканной капсулой с желтоватым содержимым. В связи с очень большими размерами кистозного образования, предварительно выполнено вскрытие кисты на ограниченном участке и её опорожнение. Осуществлено выделение капсулы кистозного образования и его полное удаление. Киста интимно предлежала к стенке прямой кишки, влагалищу и шейке матки. Гистологическое заключение: капсула дермоидной кисты с кровоизлияниями. Послеоперационный период протекал гладко. Состояние пациентки нормализовалось, все проявления заболевания купированы. В удовлетворительном состоянии больная выписана домой. Осмотрена через 6 и 12 мес. после операции — данных за рецидив образования нет.</p> <p><bold>Заключение.</bold> В доступной литературе описания подобных случаев немногочисленны. Данные ультразвукового исследования и магнитно-резонансной томографии позволили создать полное представление о взаиморасположении дермоидной кисты с органами малого таза и разработать рациональный план оперативного вмешательства.</p></trans-abstract><kwd-group xml:lang="en"><kwd>dermoid cyst</kwd><kwd>small pelvis</kwd><kwd>girl</kwd><kwd>case report</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>дермоидная киста</kwd><kwd>малый таз</kwd><kwd>девочка</kwd><kwd>клинический случай</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">Nikitina ON.
