The LT/Sv mouse strain is characterized by its abnormally high incidence of spontaneous ovarian teratomas. These tumors have been shown to originate from parthenogenetic oocytes, which are spontaneously induced to divide. Both spontaneous parthenogenesis and ovarian teratomas are extremely rare for other mouse strains, including C57BL/6J. To identify the genes responsible for this unique phenot...

Teratomas are most common germ cell tumors with two or more germ cell layers. Mature teratomas are common compared to Immature teratomas. These tumors are common in young and adolescent girls and induce large impact on their reproductive life and on the natural life span, which in turn depends upon the complications in case of Mature teratoma; Grading and staging of tumor in Immature teratoma. ...

We report a case in which a sacrococcygeal teratoma was identified and characterized on prenatal and postnatal MRI, and correlated with subsequent surgical resection.

A cytogenetic analysis of 13 mature residual teratomas following chemotherapy revealed modal chromosome numbers ranging from 52 to 85, in agreement with the flow cytometric determination of the DNA content of the tumors. At least one copy of an i(12p) was present in 12 tumors. One tumor, however, lacked that marker. The comparison between the chromosomal abnormalities found in mature residual t...

Primary retroperitoneal teratomas involving adrenal glands are exceedingly uncommon accounting for only 4% of all primary teratomas. They are more common in childhood and rarely occur in adults. Only a very few case reports have been documented in literature so far. Herein, we report a mature (benign) cystic retroperitoneal teratoma in the region of left adrenal gland in a 22-year-old otherwise...

teratomas are tumors originated from mature or immature tissues. teratomas are made up of one embryonic layer or all three embryonic layers (endoderm, mesoderm, or ectoderm). herein we report a 41-year-old man who presented with vertigo, vomiting, and tinnitus. after physical examination, laboratory evaluation and performing computed tomography, cholesteatoma was diagnosed, however, during radi...

teratomas that occur in the uterus are exceedingly rare. to the best of our knowledge there are only 22 cases of mature and immature teratomas of the uterus and cervix thus far reported in the literature. we report an unusual case of mature cystic teratoma of the uterine surface with well-differentiated adenocarcinoma of the endometrium and uterine leiomyoma along with a mature cystic teratoma ...
