Embryonal carcinoma • The tumors similar to testicular embryonal carcinoma • Rare • Age- first three decades of life • Usually present with an adnexal mass, and in half the cases, endocrine manifestations such as isosexual pseudoprecocity, irregular bleeding, amenorrhea, and hirsutism. • Serum hCG and AFP levels are typically elevated. Embryonal carcinoma is an aggressive tumor that tends to metastasize early. Embryonal carcinoma is often associated with other cell types in the metastatic sites. Pure embryonal carcinoma represents 3–6% of GCT. Choriocarcinoma is another aggressive tumor with a high potential to metastasize (lungs).
Pharynx, (Greek: “throat”) cone-shaped passageway leading from the oral and nasal cavities in the head to the esophagus and pharynx chamber serves both respiratory and digestive functions. Thick fibres of muscle and connective tissue attach the pharynx to the base of the skull and surrounding structures. Both circular and longitudinal muscles occur in the walls of the . Class XI NCERT Biology Text Book Chapter 5 Morphology of Flowering Plants is given below. The wide range in the structure of higher plants will never fail to fascinate though the angiosperms show such a large diversity in external structure or morphology, they are all characterised by presence of roots, stems, leaves, flowers and fruits.
Canine Ovarian Tumors of Germ Cell Origin two of the tumors, normal ovarian structures, including follicles, were surrounded by neoplastic cells. Six tumors contained various amounts of embryonal elements-immature structures resembling those of the embryo-and thus were considered malignant. At its lower end, the embryonal axis has the radical and root cap enclosed in an undifferentiated sheath called coleorrhiza. The portion of the embryonal axis above the level of attachment of scutellum is the epicotyl. Epicotyl has a shoot apex and a few leaf primordia enclosed in a hollow foliar structure, the coleoptile.

This page was last edited on 14 Julyat [EMBRYONAL CARCINOMA, TESTIS]. Embryonal carcinomas are very mitotically active (two arrows) with generally more than mitoses in 10 HPF. The undifferentiated nature of the tumor along with a high mitotic rate is consistent with its aggressive behavior.
[EMBRYONAL CARCINOMA, TESTIS]. Embryonal rhabdomyosarcoma cells show a consistent loss of the material from the 11p15 region (the short arm of chomosome 11), and also have a lack of gene amplification.
In addition, the cellular DNA content of embryonal rhabdomyosarcoma is hyperdiploid, with approximately – times the normal by: 3. Liver cancer is a rare malignancy in children and adolescents and is divided into the following two major histologic subgroups: Small cell undifferentiated histology hepatoblastoma and rhabdoid tumors of the liver.
