RATIONALE Endometrial stromal sarcoma (ESS) is rare, representing only approximately 0.2% of all uterine malignancies. Mixed type endometrial carcinomas (MT-ECs) are rare tumors with both type I and II features, and are difficult to diagnose. Cases of ESS and MT-ECs coexisting in the same patient are extremely rare. This study aimed to describe a case of ESS in combination with MT-ECs in a 47-y...

Endometrial stromal sarcoma (ESS) arising in the vagina is an extremely rare extrauterine endometrial stroma sarcoma, with only 4 cases reported in the literature up to date. Here we report a case of neoplasm originating from vagina. A 32-year-old woman complained of intermittent vaginal bleeding especially after intercourse. A mass with a diameter of 1.0 cm was found in the middle and upper se...

AIM To investigate the expression of matrix metalloproteinases (MMP), a group of proteolytic enzymes with a central role in extracellular matrix invasion and degradation, in stromal sarcomas. METHODS 11 endometrial stromal sarcomas (four low grade tumours, seven high grade) were stained for MMP-2, MMP-3, and MMP-9 using immunohistochemical stains. The surgical material consisted of nine hyste...

background: endometriosis is a complex estrogen-dependent disease that is defined as the presence of endometrial gland and stroma outside the uterine cavity. although the exact mechanism for the development of endometriosis remains unclear, there is a large body of research data and circumstantial evidence that suggests a crucial role of estrogen in the establishment and maintenance of this dis...

Introduction/Background Uterine sarcomas are rare tumors, representing 3 to 5% of malignant tumors the uterus. They characterized by a significant histopathological and clinical diversity. Their diagnosis is not very often made until analysis hysterectomy or myomectomy specimen, distinguishing between: carcinosarcoma; leiomyosarcoma; rhabdomyosarcoma; adenosarcoma; stromal sarcoma; und...

Atypical stromal cells of the lower female gynecologic tract have been specifically described in the vagina, vulva, and cervix, predominantly in the context of polyps. Rare cases of atypical stromal cells have been documented in the endometrium. We report a series of 15 examples of atypical stromal cells in the endometrium: 13 in endometrial polyps and two within endometrial stroma in curettage...
