Endometrial stromal tumors, their varied radiographic patterns
Urologic Radiology, 1981There is a spectrum of endometrial stromal neoplasms which extends from borderline benign to low-grade malignant. These have a definite tendency to metastasize. Proper diagnosis is important because they have an excellent prognosis with long-term survival even with evidence of recurrence or metastases. Aggressive treatment is mandatory. This represents

Endometrial Stromal Tumors of Extra-uterine Tissue
American Journal of Clinical Pathology, 1981Three extra-uterine tumors, unassociated with endometriosis, had light microscopic features of endometrial stromatosis (low-grade endometrial stromal sarcoma). Two tumors occurred in the retroperitoneum and one adjacent to the vagina. Distinctive features identifying these neoplasms as ectopic growths of endometrial stroma included prominent vessels ...

Role of Electron Microscopy in Metastatic Endometrial Stromal Tumors
Ultrastructural Pathology, 1993Endometrial stromal tumors may pose a problem in diagnosis when they appear as metastatic lesions without a known primary tumor. To determine the usefulness of electron microscopy in identifying them in these situations, optimally fixed low-grade stromal sarcomas (five), normal endometrial specimens (six), and malignant mesodermal mixed tumors (four ...

Frequency of Known Gene Rearrangements in Endometrial Stromal Tumors
American Journal of Surgical Pathology, 2011Translocations resulting in gene fusion are characteristic of endometrial stromal tumors (ESTs). Rearrangements of JAZF1, SUZ12, PHF1, and EPC1 have been reported in endometrial stromal nodules (ESNs), endometrial stromal sarcomas (ESSs), and rarely in undifferentiated endometrial sarcomas (UESs). Detection of JAZF1, SUZ12, EPC1, and PHF1 rearrangement

An endometrial stromal tumor with osteoclast-like giant cells
Annals of Diagnostic Pathology, 2005Endometrial stromal tumors (ESTs) of the uterine corpus have a striking propensity to display diverse morphological variations, including sex cord-like, smooth muscle, or skeletal muscle differentiation; fibrous change; myxoid change; or bland endometrioid-type glands.

Unusual Morphologic Features of Endometrial Stromal Tumors
American Journal of Surgical Pathology, 2005Endometrial stromal tumors with typical morphology usually do not pose diagnostic problems. However, the finding of unusual morphologic features may be misleading in the final interpretation of these tumors. Herein, we described two endometrial stromal sarcomas discovered in hysterectomy specimens of women 31 and 75 years of age.

Myxoid and Fibrous Endometrial Stromal Tumors of the Uterus
International Journal of Gynecological Pathology, 1999Ten endometrial stromal tumors of the uterus with a prominent myxoid or fibrous appearance, or both, that led to problems in interpretation are reported. The patients were 32 to 52 (mean 39) years of age. Three presented with dysfunctional uterine bleeding and one with abdominal pain.

Mesenchymal tumors of the uterus. I. A clinical and pathological study of 53 endometrial stromal tumors [PDF]
Cancer, 1966 The clinical and pathologic features of 53 endometrical stromal tumors were studied to determine which pathologic characteristics were related to the clinical behavior. Morphologically, stromal tumors were divided into 2 groups: 18 tumors with pushing margins (stromal nodules) and 35 tumors with infiltrating margins (endolymphatic stromal myosis or ...

A case of endometrial stromal tumor with epithelial elements
Medical Electron Microscopy, 1994A rare endometrial stromal tumor with marked epithelial differentiation was found in a 56-year-old female. This polypoid tumor, occupying the uterine cavity, was composed of an admixture of endometrial stromal and glandular components. Ultrastructurally and immunohistochemically, it is suggested that these epithelial elements were derived from ...
