Background
Myeloid sarcoma (MS) is a very rare condition, develops both in patients with other hematological neoplasms, and as isolated tumor. MS of the gynecologic tract is extremely rare. An available literature data about diagnosis and management of MS is summarized in the article. The role of chemotherapy, radiation therapy, surgery and bone marrow transplantation in the treatment is discussed. Polychemotherapy and allogeneic bone marrow transplantation were suggested to be the optimal treatment strategy of MS of the gynecological tract. The use of new targeted agents results in promising clinical data.
Case presentation
We are presenting a rare clinical case of a MS of the uterine cervix with concomitant bone marrow involvement and describe all the peculiarities of the clinical course, diagnosis, and treatment. The patient received chemotherapy followed by allogeneic bone marrow transplantation. The pre-transplant therapy allowed us to perform allogeneic bone marrow transplantation with the deepest response possible: complete PET-negative and MRD-negative remission of the disease.
Conclusions
MS remains a subject of discussion regarding its diagnostic and therapeutic aspects. The use of novel targeting agents can be perspective option for patient with extramedullary disease.

рожденный гиперинсулинизм (ВГИ) является частой причиной гипогликемии у детей. По данным гистологического исследования, заболевание подразделяют на диффузную, фокальную и атипичную формы. Хирургическая тактика ле-чения зависит от формы ВГИ: при фокальной форме выполняют резекцию патологической области поджелудочной железы с последующим полным выздоровлени-ем пациента, при диффузной форме с фармакорезистентным течением проводят ре-зекцию 95-98% поджелудочной железы, что приводит к развитию сахарного диабета и экзокринной панкреатической недостаточности. Дифференциальная диагностика фо-кальной и диффузной форм по клиническим и рентгенологическим признакам невоз-можна. ПЭТ/КТ с 18 F-ДОФА является «золотым стандартом» дифференциальной диагно-стики диффузной и фокальной форм заболевания. Настоящая статья является обзором литературных данных за последние 10 лет и посвящена методологическим основам и оценке информативности ПЭТ/КТ с 18 F-ДОФА у детей с ВГИ. ongenital hyperinsulinism is the most common cause of hypoglycemia in children. Congenital hyperinsulinism is divided into diffuse, focal and atypical forms. The surgical management for each form of congenital hyperinsulinism is crucially different. Focal form of congenital hyperinsulinism is cured by selective resection of the pathologic area leading to patient`s recovery. Medically unresponsive diffuse form of congenital hyperinsulinism requires the removal of 95-98% of pancreatic tissue, which may result in diabetes mellitus and exocrine pancreas insufficiency. Differential diagnosis of focal and diffuse forms according to clinical and radiological signs is impossible. Conducting with PET/CT with 18 F-DOPA is currently the "gold standard" of differential diagnosis between diffuse and focal forms of the disease. This article is a review of scientific papers for last 10 years and dedicated of methodology and diagnostic accuracy of PET/CT with 18 F-DOPA in children with congenital hyperinsulinism.
