carcinomas are consistently positive for PAX8 and GATA3 (56-58) with variable staining for HNF1-[beta], TTF-1, calretinin, and CD10.
Therefore, apparently this malformation results from anomalies of both Mullerian and Wolffian (or mesonephric
contribution to testis differentiation in the fetal mouse.
Branching ducts similar to mesonephric
ducts or ureteric buds in teratomas originating from mouse embryonic stem cells.
MRI showed the same findings of CT and a 1.9 cm elongated cyst with hyperintense content on all pulse sequences, inferring protein content, and extending from the right retrovesical region to the mesogastric region, perhaps corresponding to the persistence of the mesonephric
duct, related to ipsilateral renal agenesis [Figures 2, 3, and 4].
Vaginal septum may represent persistence of a mesonephric
duct (Harvey, 1998).

Nevertheless, cystic ovaries reported in mammalians, including guinea pigs, horses, swine, rabbits, cattle, and aged rats, have been interpreted as to have been derived from corpora lutea, ovarian follicles, ovarian surface epithelium, remnants of rete ovarii, or mesonephric
and paramesonephric ducts [25-27].

Hematopoietic stem cells of the liver originate initially from the wall of the yolk sac, then from the aortic, gonadal, and mesonephric
Other lesions such as tunnel clusters, mesonephric
hyperplasia, endometriosis, and microglandular endocervical hyperplasia may be misinterpreted as malignant.
The embryologic explanation of these variations has been presented and discussed by Felix.[sup] According to him, the developing mesonephros, metanephros, and gonads are supplied by nine pairs of lateral mesonephric
arteries arising from the dorsal aorta.
