1Department of Surgical Oncology, King George's Medical University, Lucknow, Uttar Pradesh 226003 India.

Malignant germ cell tumors (GCT) of the ovary account for 2-3% of all ovarian neoplasms and occur mostly in the second and third decade of life. Over the past three decades, survival rates for germ cell tumors have dramatically improved, coincident with more aggressive surgical staging and combination chemotherapy. Although there are several studies describing ovarian GCT and fertility-preserving surgery in the western population, there is very little Indian data. Read More

Imaging findings of ovarian dysgerminoma with emphasis on multiplicity and vascular architecture: pathogenic implications.

Abdom Radiol (NY) 2018 Jul;43(7):1515-1523

Department of Radiology, Osaka University Graduate School of Medicine, 2-2, Yamadaoka, Suita, Osaka, 565-0871, Japan.

We report the imaging findings of three ovarian dysgerminomas that coexisted with other germ cell tumors or gonadoblastomas, focusing on the distribution of tumor nests and vascular architecture, which might provide information about the pathogenesis of dysgerminomas. In a 14-year-old female with dysgerminoma and coexisting gonadoblastomas, contrast-enhanced magnetic resonance imaging (MRI) demonstrated a solid mass in the right ovary, which presented as hyperintense lobules on diffusion-weighted imaging separated by fibrovascular septa. Some small nodules were found to exist separately from the lobules (multiplicity) and to include pathological remnants of gonadoblastoma. Read More

Osmangazi University Faculty of Medicine, Departments of Pediatric Endocrinology, Eskişehir, Turkey, Phone: +90505 496 23 02 E-mail:

Ovotesticular disorder of sexual development (DSD), formerly known as true hermaphroditism, is a rare form of DSD in which both testicular and ovarian tissues are present in the same individual either in a single gonad (ovotestis) or in opposite gonads with a testis and an ovary on each side. The diagnosis of ovotesticular DSD is based solely on the presence of ovarian and testicular tissue in the gonad and not on the characteristics of the internal and external genitalia, even if ambiguous. Herein, we report two patients with ovotesticular DSD-one presenting with ambiguous genitalia on the third day after birth and the other with short stature and primary amenorrhea in adolescence.

Expression of Transcription Factors and Nuclear Receptors in Mixed Germ Cell-Sex Cord Stromal Tumor and Related Tumors of the Gonads.

Int J Gynecol Pathol 2015 Nov;34(6):528-34

Department of Pathology, Indiana University School of Medicine, Indianapolis, Indiana.

In this study, we compare the expression of OCT4, SALL4, and TSPYL1 in mixed germ cell-sex cord stromal tumor (MGC-SCST) of either gonad to that of normal adult testis, classic and spermatocytic seminoma, intratubular germ cell neoplasia, unclassified, gonadoblastoma, and dysgerminoma to determine the entity or entities that most closely resemble MGC-SCST by immunohistochemistry of germ cells. The most useful transcription factor was OCT4. In addition, to its already described value in distinguishing germinoma and embryonal carcinoma from yolk sac tumor and in differentiating classic from spermatocytic seminoma, we found that OCT4 is useful in confirming or ruling out potential malignancy in MGC-SCST of either gonad.

The relative frequency of ovarian tumors and tumor-like lesions that occur in young females (defined in this article as up to 30 years of age) differs considerably from that seen in older patients. The spectrum of lesions encountered is reviewed, with emphasis on those disproportionately seen in younger patients, particularly primitive germ cell tumors, certain tumors in the sex cord-stromal family, the distinctive tumor known as small cell carcinoma of hypercalcemic type, and selected tumor-like lesions. Comments are made initially on the relative frequency of the various well-known categories of ovarian neoplasia in the first three decades, compared to females overall, and differences within the first three decades are noted.
