INTRODUCTION Psammocarcinoma of ovary is a rare serous neoplasm characterized by extensive formation of psammoma bodies, invasion of ovarian stroma, peritoneum or intraperitoneal viscera, and moderate cytological atypia. Extensive medlar search showed presence of only 28 cases of psammocarcinoma of ovary reported till date. CASE PRESENTATION We herein report a case of psammocarcinoma of ovary...

during rectal examination of a 5-year-old pregnant cow, a single multinodular vaginal mass was palpated and removed surgically after the parturition. tissue samples of the mass were fixed in 10% neutral buffered formalin, paraffin-embedded, sectioned at 5 μm, and stained with hematoxylin – eosin and special stains.grossly, the mass had two convex and flat surfaces. multiple firm nodular masses ...

NK-2 class homeobox genes are candidate patterning and lineage regulators in diverse organisms. We report here the embryonic expression pattern of murine member, Nkx2-6. In keeping with its vertebrate relatives, Nkx2-6 was transcribed in ventrolateral embryonic structures. Expression was first detected at E8.0 in endodermal walls of the foregut pocket, tissue destined to become pharyngeal floor...

Giant cell tumor (GCT) is a benign primary bone neoplasm that usually occurre in the long bones. The skull is affected in only 1% of cases, predominantly in the sphenoid and temporal bones. Maxillary sinus involvement is exceedingly rare. The case is a 26 year-old man presented with history of gradually increasing swelling in the right side of face without any history of trauma or systemic diso...

A case of a 62 year old Japanese woman with an endometrial adenocarcinoma producing alpha-fetoprotein (AFP) is described. Microscopically, the tumour was composed of a major medullary portion and a minor tubular adenocarcinoma which had invaded the myometrium, the myometrial lymphatics and blood vessels. Neoplastic cells in the medullary portion were polygonal with glycogen-rich cytoplasm. Vasc...

Objectives: Mature cystic teratomas (MCT) originate from three germ layers: ectoderm, mesoderm and endoderm. The predictive significance of tumor markers in mature is still unclear. In this study, we aimed to evaluate the value ovarian MCTs histopathological contents tumor. Materials Methods: data 106 patients who were operated for MCT between 2015 2020 analyzed retrospectively. addition, slide...

BACKGROUND Primary mediastinal yolk sac tumor, which is also known as endodermal sinus tumor, is a rare but lethal neoplasm, and it is a kind of mediastinal non-seminomatous germ cell tumor. The current standard treatment in mediastinal non-seminomatous germ cell tumors is chemotherapy combined with postchemotherapy residual mass resection. We report on seven cases of primary mediastinal yolk s...
