Наиболее частая их локализация в плевре, где они впервые и были описаны. В печени солитарная фиброзная опухоль встречается крайне редко. Клиническая картина СФО неспецифична и не обусловлена анатомическим расположением опухоли и ее размером.</p><p>В большинстве случаев эти опухоли доброкачественные. Однако ряд из них могут иметь признаки злокачественности: агрессивное течение с возможным местным рецидивом и отдаленным метастазированием.</p><p>Основным методом лечения солитарной фиброзной опухоли печени (так же как и СФО другой локализации) при ее резектабельности является операция. Радикальное удаление опухоли в большинстве случаев приводит к выздоровлению. В последующем, оперированные пациенты должны быть подвергнуты строгому динамическому наблюдению с регулярностью как при злокачественных новообразованиях (ЗНО).</p><p>Необходимость химиотерапии и лучевой терапии в лечении солитарной фиброзной опухоли печени в клинических рекомендациях на сегодняшний день не определена. Имеются единичные сообщения об использовании химио или лучевой терапии для лечения случаев, когда резекция опухоли нерадикальная или имеются признаки злокачественного новообразования.</p><p>В литературе неоднократно встречаются сообщения о сочетании солитарной фиброзной опухоли какой-либо локализации с злокачественными новообразованиями других органов у этих же пациентов.</p><p>В данной работе мы приводим клинический случай солитарной фиброзной опухоли печении и высокодифференцированной аденокарциномы прямой кишки у женщины шестидесяти четырех лет. Больной была выполнена резекция первого сегмента левой доли печени. Через полтора месяца - трансанальное иссечение ворсинчатой опухоли прямой кишки. При патогистологическом иммуногистохимическом исследовании опухоли печени была выявлена злокачественная солитарная фиброзная опухоль. При исследовании ворсинчатой опухоли прямой кишки - высокодифференцированная аденокарцинома с глубиной инвазии подслизистого слоя стенки кишки до 1/3 (T1sm1 по Kikuchi).</p><p>При динамическом наблюдении на протяжении двадцати пяти месяцев после операции у пациентки признаков рецидива опухолей и метастазирования нет.</p></abstract><trans-abstract xml:lang="en"><p>Solitary fibrous tumors (SFT) are rare spindle cell mesenchymal neoplasms of presumably fibroblastic origin with undefined malignancy potential and rare metastasis. Their most frequent localization is in the pleura, where they have been first described. The incidence of solitary fibrous tumors localized in liver is extremely low. The clinical picture of SFT is nonspecific and is not due to the anatomical location of the tumor and it's size.</p><p>In the majority of cases these tumors are benign. However, a number of them still may have signs of malignancy: an aggressive course with possible local recurrence and distant metastasis. The main method of treatment of hepatic solitary fibrous tumor (as well as SFT of other localization) with it's resectability is surgery. Radical removal of the tumor in the majority of cases leads to recovery. Subsequently, the operated patients should be subjected to strict dynamic observation with regularity as in malignant neoplasms (MN).</p><p>The importance for chemotherapy and radiation therapy in the treatment of hepatic solitary fibrous tumor has not been determined in clinical guidelines to date.</p><p>There are isolated reports of the use of chemotherapy or radiation therapy for the treatment of cases when tumor resection is not radical or there are signs of malignant neoplasm.</p><p>In literature, there are numerous reports of a combination of a solitary fibrous tumor of any localization with malignant neoplasms of other organs in the same patients.</p><p>In this report, we represent a clinical case of a 64-year-old woman, who had a solitary fibrous tumor of the liver and highly differentiated rectal adenocarcinoma. The patient underwent resection of the first segment of the left lobe of the liver. After a month and a half, transanal excision of the villous tumor of the rectum. The pathologic and immunohistochemical examination of the liver tumor revealed a malignant solitary fibrous tumor. After researching villous tumor of the rectum - a highly differentiated adenocarcinoma with a depth of invasion of the submucous layer of the intestinal wall up to 1/3 (T1sm1 according to Kikuchi). During dynamic observation for twenty-five months after the operation, the patient has no signs of tumor recurrence and metastasis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>злокачественная солитарная фиброзная опухоль</kwd><kwd>иммуногистохимическое исследование</kwd><kwd>печень</kwd><kwd>аденокарцинома</kwd><kwd>прямая кишка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>malignant solitary fibrous tumor</kwd><kwd>Immunohistochemical study</kwd><kwd>liver</kwd><kwd>adenocarcinoma</kwd><kwd>rectum</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">Печетов А.
