Endometrial stromal sarcomas (ESSs) belong to the rarest uterine malignancies (prevalence category <1-9/1,000,000). According to the new 2014 World Health Organisation (WHO) classification, they are separated into four categories; benign endometrial stromal nodules (ESNs), low grade endometrial stromal sarcomas (LG-ESSs), high-grade endometrial stromal sarcomas (HG-ESSs) and undifferentiated uterine sarcomas (UUSs). Due to heterogeneous histopathologic appearance these tumors still represent diagnostic challenge, even for experienced pathologists...

Endometrial stromal nodules are rare benign tumors that appear as well-circumscribed globular masses in the myometrium. In this report, a myometrial mass exhibited heterogeneous hyperintensity without hypointense bands on T2-weighted images and homogeneous isointensity on T1-weighted images. A dynamic contrast study revealed the same degree of uterine myometrial enhancement only in the marginal area. The structures were pathologically confirmed to correspond with proliferating endometrial stromal cells. Herein, we report this rare tumor and the correlation between magnetic resonance imaging and pathological findings...

Endometrial stromal tumors are rare, and endometrial stromal nodule is the least common. In the region of Middle Jutland, Denmark, only two cases are reported since 1995. The nodules are benign; nevertheless, hysterectomy is the treatment of choice. Tumor margins are required for diagnosis and essential to differentiate it from an invasive stromal sarcoma whose prognosis is very different. We report a rare case of a 38-year-old woman, with presurgical diagnosis of a uterine tumor/polyp. She presented with nausea and changes in bleeding pattern and initially had a transcervical polyp resection performed...

INTRODUCTION: The endometrial stromal sarcoma (ESS) is a very rare uterine sarcoma, counting for 1-3% of all gynecologic malignancies. ESS represents 0.2-8% of all uterine malignant tumors and accounts for about 10% of all uterine sarcomas. With regard to chromosomal aberrations, very little is known about benign and malignant endometrial stromal tumors. METHODS: 30 tumors, consisting of 4 cases of benign endometrial stromal nodule (ESN), 22 cases of low-grade ESS and 4 cases of undifferentiated endometrial sarcoma (UES), were analyzed by array-comparative genomic hybridization (aCGH)...

Among the endometrial tumour endometrial stromal nodule are very rare. It is one of the form of endometrial stromal tumour. There are no definite presurgical diagnosis and diagnosis in most instances by microscopy. Hysterectomy is the treatment of choice to evaluate the tumour margin to differentiate it from stromal sarcoma. We present a case of 40 years woman, ultrasonographically diagnosed as leiomyoma and ovarian cystadenoma, underwent a total abdominal hysterectomy with one sided salpingo-oophorectomy. Microscopic examination show an endometrial stromal nodule and serous cystadenoma of the ovary...

Preoperative differentiation of benign endometrial stromal nodule (ESN) from malignant low-grade endometrial sarcoma (LGESS) is challenging, because it requires histological evaluation of the tumor-myometrium interface, which is difficult to obtain in conventional endometrial curettage. A 72-year-old postmenopausal woman presented with 5-year history of persistent vaginal bleeding. Histological examination of the endometrial curettage specimen revealed hyperplasia of apparently normal endometrial stromal cells...

Endometrial stromal tumors (ESTs) are composed of cells resembling endometrial stroma, and are divided into benign and malignant types based on morphology. Endometrial stromal nodule (ESN) is a benign localized tumor, and endometrial stromal sarcoma (ESS) is an infiltrative and potentially metastatic neoplasm. A series of genetic aberrations contribute to pathological diagnosis of ESTs. At present, subsets of ESN and ESS-low grade (ESS-LG) are characterized as JAZF1-SUZ12/JJAZ1 gene fusion. The ESTs that show higher grade atypia but lack nuclear pleomorphism include YWHAE-FAM22 ESS...

Low-grade endometrial stromal sarcoma (ESS) is an uncommon gynecologic malignancy of mesodermal origin. Pulmonary metastasis of low-grade ESS can occur years and decades after the treatment of the primary disease. Low-grade ESS is frequently mistaken as benign uterine neoplasm like uterine leiomyoma, which can potentially lead to a misdiagnosis. We present a case of a 42-year-old woman with low-grade ESS, that initially presented as an incidental lung mass with multiple pulmonary nodules, seven years after an uterine myomectomy...

Endometrial stromal sarcoma are rare malignant tumors of the uterus and has been described as the second most common malignant uterine mesenchymal tumor. The diagnosis is confirmed on hysterectomy for a presumed benign disease. In the latest World Health Organization (WHO) classification (2003), the term endometrial stromal tumor is applied to neoplasms typically composed of cells that morphologically resemble endometrial stromal cells of the nonneoplastic proliferative phase endometrium. The WHO recognizes three categories of endometrial stromal tumors: Endometrial stromal nodule, low-grade endometrial stromal sarcomas (LGESS), and undifferentiated endometrial sarcoma...

OBJECTIVES: To assess the difficulties associated with diagnosing endometrial stromal tumors (ESTs) on endometrial biopsy. METHODS: We examined 25 endometrial biopsy specimens from 19 consecutive women diagnosed with either endometrial stromal nodule (n = 3) or endometrial stromal sarcoma (n = 16). RESULTS: Rereview of the biopsy specimens revealed a stromal fragment suspicious for an EST in 16, of which eight had received a benign diagnosis on initial review...

Four myxoid variant of uterine mesenchymal tumors are reported. One was a low grade stromal sarcoma with infiltrative margins and the others were well circumscribed tumors corresponding to an endometrial stromal nodule and two leiomyomas. They were hypocellular neoplasms composed of stellated cells with an abundant Alcian Blue positive myxoid matrix. The myxoid nature of the neoplasms obscured their cellular nature and made the distinction between smooth muscle and endometrial stromal tumors difficult. Endometrial stromal tumors, showed very focal areas of small basophilic cells, characteristic of endometrial stroma...

Endometrial stromal nodule (ESN) is the least common of the endometrial stromal tumors. They are rare neoplasms which are diagnosed in most instances by light microscopy. Although such nodules are benign, hysterectomy has been considered the treatment of choice to determine the margins of the tumor required for diagnosis and to differentiate it from invasive stromal sarcoma Whose prognosis is totally different. We report a case of a 45 years old woman, with presurgical diagnosis of adnexal mass or uterine tumor...

Cystic fibrohistiocytic tumor of the lung is a rare neoplasm. In many cases it represents a metastasis from a benign or low-grade fibrohistiocytic tumor of the skin, but occasionally it may be primary. Radiologically it usually occurs as a cystic change of multiple pulmonary nodules, and pneumothorax is the most frequent presenting symptom. We present here a 16-year-old man with recurrent right pneumothorax. The patient had no history of cutaneous fibrohistiocytic lesions. He underwent videothoracoscopic right apical segmentectomy, right lower lobe nodulectomy, and pleuroabrasion...

Uterine stromal neoplasms are classified into endometrial stromal nodules and stromal sarcomas, as well as undifferentiated sarcomas. The two former groups demonstrate identical histological composition, consisting of small monomorphous cells with scant cytoplasm and round nuclei and typically contain numerous arteriolar-type vessels. Stromal tumors are distinct from stromal nodules by virtue of their myometrial and vascular invasion. Undifferentiated sarcomas consist of polymorphic cells and lack any cytological similarity to the stroma of normal proliferative endometrium...

AIMS: Uncommon cases of lung metastasis from different types of uterine neoplasms with a long tumour-free interval after hysterectomy are reported. METHODS AND RESULTS: Four cases were retrieved from our surgical pathology archives. Case 1 was a 68-year-old woman who had three pulmonary nodules 23 years after hysterectomy for low-grade endometrial stromal sarcoma (LGESS). The nodules obtained with video-assisted thoracic surgeries were consistent with metastatic LGESS...

Chimeric gene products, most often resulting from chromosome translocations, have been considered unique features of cancer, or at least of cells at high risk for becoming cancerous. Chimeric JAZF1-JJAZ1 mRNA transcribed from DNA spanning the site of recombination in the (7;17)(p15;q21) chromosomal translocation found in half of endometrial stromal sarcomas and most cases of benign stromal nodules is one such example. The recent finding that chimeric JAZF1-JJAZ1 mRNA can also be detected in normal endometrial stromal cells suggests that chimeric gene products are not limited to cancer or pre-cancerous cells...

A 28-year-old patient presented with a 5 cm endometrial stromal tumor situated at the uteroplacental interface, which was diagnosed ultrasonographically at the 28th week of pregnancy. The tumor was asymptomatic and closely attached to the decidua; after a normal term delivery, it was revealed to be embedded within the placenta. Microscopically, the neoplasm had a high mitotic rate and characteristic features of endometrial stromal tumor, such as CD10, progesterone receptor positivity, and an expansile linear, non-infiltrative pushing border...

Nonrandom cytogenetic abnormalities of chromosomes 6, 7, and 17 have been reported within low-grade endometrial stromal sarcomas (LGESSs), and among these abnormalities, the t(7;17)(p15;q21) is the most common aberration described. Previously we had shown that this translocation joins 2 genes, JAZF1 and JJAZ1, located on chromosomes 7 and 17, respectively. To determine the frequency of the t(7;17), we analyzed 4 stromal nodules and 24 LGESS by both reverse transcriptase-polymerase chain reaction and fluorescence in situ hybridization (FISH)...
