Lipid Cell Tumor of the Ovary

The history and the pathological findings will be presented along with the review of the literature. [ncbi.nlm.nih.gov]

Recently, authors experienced a case of lipid cell tumor of the left ovary in a 19 year old female, who presented with amenorrhea and hirsutism for 4 years. Grossly, the ovary was well encapsulated, and measured 6.5x6x4.5 cm. [jpatholtm.org]

  • Virilization

    Lipid cell tumor of the ovary is among the rarest tumors belonging to the virilizing group of ovarian neoplasms. A lipid cell tumor of the ovary is described in an 18-year-old woman with secondary amenorrhea, hirsutism, and frank virilization. [ncbi.nlm.nih.gov]

    The tumor was a cause of virilizing symptoms and infertility in the patient. Surgical removal of the tumor reverted the symptoms of virilization, and the patient subsequently conceived. [jmedicalcasereports.biomedcentral.com]

    Symptoms of virilization were present in the form of deepening of voice and thinning of scalp hair. [ijdvl.com]

    Histology Cyst cavity is often lined with keratinized squamous epithelium and usually contains abundant sebaceous and sweat glands (Figure 6). There is usually a raised protuberance projecting into the cyst cavity known as the Rokitansky nodule. [intechopen.com]

  • Suggestibility

    Peripheral and ovarian vein steroid concentrations suggest that the tumor produced androgens preferentially by way of the delta 4 steroidogenesis pathway. [ncbi.nlm.nih.gov]

    Peripheral and ovarian vein steroid concentrations suggest that the tumor produced androgens preferentially by way of the Δ 4 steroidogenesis pathway. 1989 S. [karger.com]

    Sertoli-Leydig cell tumours As the name suggests, Sertoli-Leydig cells contain both Sertoli and Leydig cells. [atlasgeneticsoncology.org]

    A CT scan confirmed a 10.4 5.9 cm solid left adnexal mass as well as another solid nodule mass measuring 4.9 4 cm in the cul-de-sac and mild ascites (Figures 1(c) and 1(d)). [hindawi.com]

  • Secondary Amenorrhea

    A lipid cell tumor of the ovary is described in an 18-year-old woman with secondary amenorrhea, hirsutism, and frank virilization. [ncbi.nlm.nih.gov]

    However, menstrual irregularities such as oligomenorrhea, menorrhagia, and secondary amenorrhea tend to be the hallmark of these tumors in women of reproductive age. [www1.cgmh.org.tw]

    These tumors produce high levels of estrogen, which causes its characteristic symptoms: menometrorrhagia; endometrial hyperplasia; tender, enlarged breasts; postmenopausal bleeding; and secondary amenorrhea. [en.wikipedia.org]

  • Ovarian Disorder

    Young and Scully s 1979 classification of ovarian tumors with endocrine manifestations ( Figure 1 ) includes sex-cord stromal tumors, steroid-cell tumors and other ovarian disorders with endocrine function. [omicsonline.org]

Tumor markers such as CA-125, CEA, and CA 19-9 are typically not helpful in the workup. [hindawi.com]

  • Ovarian Mass

    Pathology On gross examination, the left adnexa consisted of a normal fallopian tube attached to an 11 8 4 cm solid ovarian mass with a smooth intact surface. [hindawi.com]

Prompt diagnosis and treatment are emphasized in this potentially malignant and disfiguring androgenic tumor that is readily amenable to surgery. [ncbi.nlm.nih.gov]

Statistics and Prognosis Granulosa cell tumors occur at the peak age of 50-55, but can occur earlier in life. They are known to reappear as much as a decade or two after one is diagnosed. [knowcancer.com]

or therapies New developments in treatment As with any cancer, prognosis and long-term survival can vary greatly from individual to individual. [stanfordchildrens.org]

The prognosis of SCT is usually good and correlates with the stage and degree of differentiation of the tumor [ 3 ]. [ispub.com]

Prognosis of these germ cell tumors is excellent. [intechopen.com]

The prognosis is similar to that of the latter tumor. [glowm.com]

Etiology The exact etiology of dysgerminomas is not identified, though recent molecular studies have implicated loss of function with potential tumor suppressor gene TRC8/RNF139 as a possible etiology [48]. [intechopen.com]

Discussion In a case of rapid-onset hirsutism, virilization, and menstrual irregularity, neoplastic etiology should always be kept in mind. Therefore, comprehensive workup is required. [edm.bioscientifica.com]
