Endometrial Stromal Nodules and Endometrial Stromal Tumors With Limited Infiltration

The American Journal of Surgical Pathology, 2002
Experience with endometrial stromal nodules (ESNs) is limited, and no series has been published since the frequent misdiagnosis of highly cellular leiomyomas as ESNs was highlighted. Additionally, although the entirely well-circumscribed margin of most ESNs readily allows a separation from endometrial stromal sarcomas with their typical permeative ...

Endometrial stromal tumors, their varied radiographic patterns

Urologic Radiology, 1981
There 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

Role of Electron Microscopy in Metastatic Endometrial Stromal Tumors

Ultrastructural Pathology, 1993
Endometrial 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, 2011
Translocations 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, 2005
Endometrial 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, 2005
Endometrial 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, 1999
Ten 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.

A case of endometrial stromal tumor with epithelial elements

Medical Electron Microscopy, 1994
A 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 ...

Malignant Potential of Endometrial Stromal Tumor With Limited Infiltration

International Journal of Surgical Pathology, 2013
Endometrial stromal tumors (ESTs) with limited infiltration were first proposed by Dionigi et al. 1 However, the prognostic significance of these tumors is unclear. We report a case of a 60-year-old woman who presented with a prolapsed uterine corpus and then underwent laparoscopic-assisted ...

Analysis of MDM2 Amplification in 43 Endometrial Stromal Tumors

International Journal of Gynecological Pathology, 2015
MDM2 amplification is known to occur in a variety of neoplasms and its detection by fluorescence in situ hybridization is helpful in distinguishing well-differentiated and dedifferentated liposarcoma from classic lipoma. We recently evaluated a mesenteric mass initially diagnosed as dedifferentiated liposarcoma, largely due to the neoplasm's myxoid ...
