A case of metastatic granulosa cell tumour of the ovary is reported. Investigations revealed a secondary tumour in segment VI and VII of the liver. Right hepatic resection was performed. Microscopic findings revealed a tumour with histological features identical to that removed eleven years before.

We present an unusual case of a young woman with rare bilateral, very aggressive ovarian granulosa cell tumour (GCT), comprised of granulosa, sarcomatoid and fibrothecomatous fields with significantly different immunostaining of primary and metastatic tumours showing stronger WT1, Bcl2, fascin and EGFR expression in metastases. Despite radical surgery and chemotherapy the tumour recurred rapidl...

OBJECTIVES Subjective ultrasonographic assessment is currently considered to be the best method of differentiation between various types of ovarian tumors. The aim of the study was to evaluate selected ultrasonographic features and CA125 levels of hormonally active ovarian tumors. MATERIAL AND METHODS A total of 1135 women with ovarian tumors were diagnosed between 2006 and 2014 at the Divisi...

Background: Germ cell development processes are influenced by soluble factors and intercellular signaling events between them and the neighboring somatic cells. More insight into the molecular biology of the germ cell development from embryonic stem (ES) cells and investigation of appropriate factors, specifically those targeting differentiation process, is of great importance. In this study, w...

Ovarian granulosa cell tumors (GCTs) represent 3%-5% of all ovarian malignancies. Treatments have limited proven efficacy and biologically targeted treatment is lacking. The aim of this study was to investigate the role of Notch signaling in the proliferation, steroidogenesis, apoptosis, and phosphatidylinositol 3-kinase (PI3K)/AKT pathway in a FOXL2-mutated granulosa tumor cell line (KGN) repr...

Mediastinal lesions occur in a wide variety of clinical conditions. Metastatic granulosa cell tumour (GCT) in the mediastinum is a rare occurrence. We report a case of a woman who had a metastatic (GCT) in her mediastinum 40 years after treatment of the initial neoplasm. Surgical resection of the mediastinal mass revealed a low-grade epithelioid neoplasm with coffee bean-shaped nuclei and immun...

Ovarian granulosa cell tumors (TGO) are rare neoplasms. They arise from sex cord stromal cells of the ovaries. They are characterized by their slow natural history, and their tendency to relapse long time after the initial diagnosis. Complete staging surgery of the disease is the cornerstone of treatment. Chemotherapy is indicated for localized tumors with a high risk of recurrence, and for rec...
