Ovarian adult-type granulosa cell tumor concomitant with simple endometrial hyperplasia: a case study with selected immunohistochemistry.

J Int Med Res 2020 Apr 23;48(4):300060519886984. Epub 2019 Dec 23.

IInd Department of Gynecology, Lublin Medical University, Lublin, Poland.

Ovarian adult-type granulosa cell tumors are often associated with endometrial hyperplasia or even uterine cancer. Herein, we present a case report of a 65-year-old female patient who had undergone curettage of the uterine cavity several times due to abnormal and irregular uterine bleeding. Owing to recurrent episodes of vaginal bleeding as well as ineffective pharmacological treatment of simple endometrial hyperplasia without atypia, the patient underwent a laparoscopically-assisted vaginal hysterectomy.

Leptin Receptor Antagonists' Action on HDAC Expression Eliminating the Negative Effects of Leptin in Ovarian Cancer.

Cancer Genomics Proteomics 2018 Jul-Aug;15(4):329-336

Department of Physiology and Toxicology of Reproduction, Institute of Zoology and Biomedical Research, Jagiellonian University in Kraków, Krakow, Poland

Background/aim: A common finding in cancer cells is the overexpression of histone deacetylases (HDACs), leading to altered expression and activity of numerous proteins involved in carcinogenesis. Considering that leptin can modulate the levels of HDACs, we hypothesised that leptin receptor antagonists can alter HDAC expression.

Materials And Methods: HDAC expression in cells exposed to leptin and leptin receptor antagonists (SHLA and Lan2) were evaluated in ovarian epithelial (OVCAR-3, CaOV3) and folliculoma (COV434, KGN) cells. Read More

Superactive human leptin antagonist (SHLA), triple Lan1 and quadruple Lan2 leptin mutein as a promising treatment for human folliculoma.

Cancer Chemother Pharmacol 2017 Oct 31;80(4):815-827. Epub 2017 Aug 31.

Department of Physiology and Toxicology of Reproduction, Institute of Zoology and Biomedical Research, Jagiellonian University, Gronostajowa 9, 30-387, Kraków, Poland.

Purpose: There are no data showing a direct correlation between obesity and increased blood leptin levels with folliculoma. Moreover, folliculoma is not the best studied among other ovarian cancer types. We investigated whether oestradiol can modulate ObR expression in some oestrogen-responsive tissues and that leptin exerts its activity not only via the leptin receptor but also through cross talk with other signalling systems.

Two cases of neoplasia of basal cell origin affecting the axillary region in anseriform species.

J Avian Med Surg 2009 Sep;23(3):214-21

Maryland Zoo, Baltimore, Druid Hill Park, Baltimore, MD 21217, USA.

Neoplasms of the skin are occasionally seen in domestic birds but are uncommon in nondomestic birds. An 8-year-old male hooded merganser (Lophodytes cucullatus) was presented with bilateral axillary ulcerative lesions that improved but did not resolve with empiric antibiotic and antifungal therapy. Skin biopsies were taken, and bilateral feather folliculomas were diagnosed on histopathologic examination. Read More

[Current views on treatment of the ovarian granulosa-cell tumor].

Ginekol Pol 2008 Jan;79(1):42-6

Katedra i Klinika Ginekologii Onkologicznej i Pielegniarstwa Ginekologicznego UMK w Toruniu.

The granulosa-cell tumor (folliculoma) is a rare type of ovarian neoplasm, accounting for 5% of all cases. It is the most common type of sex cord-stromal tumors, diagnosed in 70% of cases. The granulosa-cell tumor is a hormone active one, originating from granulosa cells which produce estradiol. Read More

[The influence of ovarian tumour histopathological diagnosis on prognostic values of the sonomorphological index].

Ginekol Pol 2006 Jul;77(7):516-22

Klinika Ginekologii Operacyjnej Akademii Medycznej w Poznaniu.

Objectives: The purpose of the study was to evaluate the helpfulness of sonomorphological index in preoperative diagnosis of ovarian tumours.

Material And Method: 686 patients diagnosed and treated because of adnexal tumours were analyzed. At the admission day the patient underwent an ultrasonographical examination that stated morphology of tumour using the sonomorphological index (SM). Read More

[Personal observations of puberty in girls after unilateral ovariectomy].

Endokrynol Diabetol Chor Przemiany Materii Wieku Rozw 2004 ;10(2):123-6

Department of Endocrinology for Children and Adolescents, Wrocław, Poland.

The authors present the course of puberty in three girls after surgery because of hormonally active ovarian tumours diagnosed and operated at the age of 3, 6 and 9 years, respectively. In the youngest patient with folliculoma ovari chemotherapy was also given, and girl No. 3 with luteinic capsule was treated for one year with decapeptyl because idiopathic precocious puberty was diagnosed.

K-ras gene point mutations and p21ras immunostaining in human ovarian tumors.

Eur J Gynaecol Oncol 2004 ;25(4):484-8

2nd Department of Gynecology, University School of Medicine, Lublin, Poland.

It is well recognized that genetic alterations within oncogenes, tumor suppressor genes, DNA mismatch repair and excision repair genes contribute to tumorigenesis within the human ovary. This study was undertaken to screen for the existence of K-ras gene point mutations in paraffin-embedded slides randomly selected from benign and malignant ovarian tumors applying the PCR-RFLP technique. Expression of p21ras was also assessed in 30 primary ovarian adenocarcinomas immunohistochemically. Read More

Feather folliculoma in a captive-bred barn owl (Tyto alba).

Avian Dis 1999 Jul-Sep;43(3):616-21

Department of Pathobiology, University of Connecticut, Storrs 06269-3089, USA.

Proliferative cutaneous lesions are frequently encountered in examination of avian species. Tumors of the skin have been reported in many bird species, although comparatively less is known about the incidence of integumentary neoplasia in nondomesticated species than in production or companion species. An adult male, 9-yr-old, captive-bred barn owl (Tyto alba) was presented for examination of a proliferative skin mass of several months' duration on the left wing. Read More

[Methylation of DNA in tissue of ovarian malignant tumors in women].

Ginekol Pol 1993 Apr;64(4):169-73

II Kliniki Ginekologii Operacyjnej AM, Lublinie.

DNA methylation level from woman ovarian malignant tissues was investigated by 32P postlabeling of the single nucleotides, separation on TLC with followed autoradiography and Cerenkov counting. Slight differences in DNA methylation extent were found in malignant ovarian tumors as compared to normal myometrium and benign uterine tumor [myomas]. Lowest level of m5dC in relation to C and also in relation to total DNA was found in carcinoma embryonal tissue whereas maximal DNA methylation level was obtained in folliculoma tissue. Read More
