Ovarian cysts are an extremely common gynecological problem in adolescent. Majority of ovarian cysts are benign with few cases being malignant. Ovarian serous cystadenoma are rare in children. A 14-year-old presented with abdominal pain and severe abdominal distention. She underwent laparotomy and after surgical removal, the mass was found to be ovarian serous cystadenoma on histology. In concl...
Surface epithelial tumors account for more than 90% of ovarian tumors, of which serous tumors comprise 46%. Sex-cord stromal tumors constitute 8% of ovarian tumors, fibroma being the commonest, comprising 70% in this category. Combination of different types of tumors can occur in ovary with most common being Mucinous cystadenoma and Brenner tumour. We report a case of a very rare combination of...
Clear cell ovarian cancer is an epithelial ovarian cancer histotype that is less responsive to chemotherapy and carries poorer prognosis than serous and endometrioid histotypes. Despite this, patients with these tumors are treated in a similar fashion as all other ovarian cancers. Previous genomic analysis has suggested that clear cell cancers represent a unique tumor subtype. Here we generated...
Epithelial ovarian cancer comprises three major histological subtypes (serous, mucinous, and endometrioid), and it is becoming clear that the developmental pathways for these subtypes are fundamentally different. In particular, endometrioid ovarian cancers probably arise by the malignant transformation of ectopic endometrial implants called endometriosis and not the ovarian surface epithelium. ...
BACKGROUND Even though ovarian tumors are not generally considered estrogen-sensitive, estrogens may still have an impact on ovarian tumor progression. The recently identified trans-membrane estrogen receptor GPER is involved in rapid estrogen signaling. Furthermore, it binds selective estrogen receptor modulators with agonistic effect, which could explain tamoxifen controversies. METHODS GPE...
ovarian borderline serous tumors are uncommon. combination of borderline serous adenofibromatous tumor and prominent micro papillary architecture is not previously reported. we report a case of borderline papillary serous adenofibromatous tumor (also called serous adenocarcinofibroma) with extensive micropapillary pattern in a 27 year-old married woman. she was infertile and presented with diff...
Approximately 6-7% of all adnexal masses found during physical examination are actually metastatic ovarian tumors, which often masquerades as the primary ovarian tumor. The circumstances leading to the discovery of these metastatic lesions depends on the site of the primary tumor. The ovaries may be only slightly enlarged or measure 10 cm or more. Ovarian metastases are bilateral in approximate...
Ovarian cancer is the gynecological cancer with the poorest prognosis. One significant reason is the development of resistance to the chemotherapeutic drugs used in its treatment. The large GTPase, hGBP-1, has been implicated in paclitaxel resistance in ovarian cell lines. Forced expression of hGBP-1 in SKOV3 ovarian cancer cells protects them from paclitaxel-induced cell death. However, prior ...
BACKGROUND Sphingosine-1 receptor 1 (S1P1) plays a major role in regulating lymphocyte egress from peripheral lymph tissue. Lymphocyte trafficking is potentially a critical response to tumors and to tumor vaccines. Also, the receptor has been shown to influence metastasis. However, there is little information on its expression in the aged ovary or ovarian tumors. As a basis for further studies ...
Ovarian abnormalities such ovarian cysts, tumors, and polycystic ovaries are one of the serious disorders affecting women's health. In ultrasound imaging abnormalities, noise during capturing image its transmission process frequently corrupts image. order to make best judgments possible at appropriate moment, cysts in females must be accurately detected. computer aided diagnosis preprocessing i...
