They can generally be subdivided into two types: pure or mixed lipomas. A third group of malignant neoplasm has been proposed, which is liposarcoma; however, this is very rare. In this article, we report three patients having lipomatous uterine tumors, including one uterine lipoma and two uterine lipoleiomyomas. All our patients are postmenopausal women, which is the typical presenting age group. They did not have any symptoms and the tumors were only found incidentally on imaging. However, in some patients, symptoms may uncommonly occur. If symptoms occur, these are similar to those of leiomyoma. We illustrate the imaging features of the tumors in our patients with ultrasound, computed tomography (CT) scan and magnetic resonance imaging (MRI). The tumor typically appears as a well-defined homogenously hyperechoic lesion on ultrasound. It shows fat density on CT scan and signal intensity of fat on MRI. MRI is the modality of choice because of its multiplanar capability and its ability to demonstrate fat component of the lesion, as illustrated in our cases. We also discuss the importance of differentiating lipomatous uterine tumors from other lesions, especially ovarian teratoma which requires surgical intervention. Despite the rarity and the common asymptomatic nature of the tumors, we believe that this series of three cases demonstrates a review of a rare tumor which provides important knowledge for patient management.展开更多

The occurrencer of papillary patterns of en- dometrial adenocarcinoma had been reportedly recognized since 1900, while until the late 1970s several authors have had described a variant of papillary endometrial cancer. UPSC is a morphologically unique variant of endometrial carcinoma that is pathologically defined by the presence of high nuclear grade, distinct papillary architechtural changes, psammoma bodies, and extensive lymph - vascular space invasion. CA125 is often mentioned a useful tumor marker either for diagnosis before starting treatment or in monitoring recurrence. The optimal treatment of UPSC is controversial and appears to be dependent upon the stage of the disease. Primary surgery comprised of TAH/BSO and complete staging is the mainstay of treatment. The patients with recurrent UPSC in many studies were treated with various combinations of surgery , radiation therapy, and chemotherapy. The molecular basis for the gneeral poor response of UPSC to adjuvant chemotherapy and radiotherapy is not well under- stood. UPSC tumors are more often aneuploid and contain overexpressed mutant p53 protein as compared to endometrioid adenocarcinoma. Unlike patients with adenocarcinoma of the endometrium, women with UPSC were less likely to be obese, hypertensive, or diabetic.展开更多

False positives were eliminated by reverse Northern analysis. Positives were confirmed by Northern blot analysis. RESULTS: [1] Four of 69 cDNA fragments (3 up-regulated named L1, L2 and L3 and 1 down-regulated named Mi in leiomyoma) were confirmed by Northern analysis. [2] Sequence comparison and Northern analysis proved that Li is exactly the human ribosomal protein Si9. [3] It was present ubiquitously in i3 tissues tested but in various levels and even in different size. [4] Li was highly expressed in parotidean cystadenocarcinoma, pancreatic cancer and breast cancer examined. [5] No mutations have been found in human uterine leiomyomas (n=6). CONCLUSIONS: hRPSi9 overexpression might be a universal signal in rapid cell growth tissues.展开更多
