BACKGROUND:Teratoma, a tumor containing variety of tissues, is broad diagnosis mature teratoma, immature and teratomas with malignant transformation. The forms during embryological development secondary to unsuccessful migration primordial germ cells. A specific type human-like features, called fetiform teratoma. teratoma often compared confused fetus in fetu, reabsorbed twin. While these tumor...

Experiments using different species of the plant Nicotiana and strains of the bacterium Agrobacterium tumefaciens showed that teratoma formation from crown galls was dependent on the combination of bacterial Ti plasmid and host plant used.

We report a rare case of large immature retroperitoneal teratoma in a neonate. The diagnostic and therapeutic challenges of dealing with such a case have been discussed and the relevant literature reviewed.

Objective To investigate the role of ovarian cystectomy in patients with early-stage immature teratoma. Methods A retrospective review was undertaken on patients diagnosed pathologically with immature teratoma and with malignant lesions confined to the ovary. Patients were included if they had been treated between January 1997 and December 2015 at the Obstetrics and Gynaecology Hospital of Fuda...

Small bodies, comparable in their morphology with that of the early developmental stages of mammalian embryos, are observed uncommonly in certain testicular teratomata (Melicow, 1940; Dixon and Moore, 1953; Evans, 1956); and although an enormous number of these embryolike structures may be scattered haphazardly throughout a teratomatous growth, it is only rarely that such bodies (Figs. 2, 5) mi...

Germ cell tumors (GCTs) represent a well-recognized group of heterogeneous neoplasms with diverse clinical, histopathological, diagnostic, and prognostic characteristics. We present a rare case of a locally aggressive, chemotherapy-resistant immature mediastinal teratoma with a peculiar histological finding of a multilineage somatic-type malignant degeneration. A 21-year-old male patient presen...

We present a case of an adult female who presented mildly symptomatic and with a history of having a mass removed from her neck as an infant. Radiographic imaging detected the presence of a heterogeneous, encapsulated mass in the parapharyngeal space that was surgically resected, and subsequently pathologically confirmed to be a benign, mature cystic teratoma.
