Persistent urogenital sinus (UGS) is a developmental anomaly. It represents one of the most complex problems that a pediatric surgeon may deal with. We report the case of a patient with UGS treated at 3 years of age by anterior sagittal transrectal approach and en bloc sinus mobilization. The procedure was performed with the patient prone with the initial idea of performing an anterior sagittal...

We report the case of a 44-year-old woman who presented with vaginal bleeding. Vaginal examination and colposcopy showed a tumor on the anterior lip of the cervix. Trans-vaginal sonography revealed a thickened endometrium with accentuated vascularization. Samples from the tumor and endometrium were collected by byopsic curettage. Histopathologic examination showed atypical hyperplasia of the en...

The P19 embryonic stem (ES) cells are derivatives of the inner cell mass of a mouse blastoderm, are multipotent and can give rise to all three germ layers [1]. They are anchorage-independent, display no contact inhibition, and are tumorigenic [2]. The P19 ES cell line was originally derived from a teratocarcinoma in C3H/HE mice, produced by grafting an embryo at 7 days of gestation to the teste...

OBJECTIVE To describe a new system for classifying genital ambiguity and urogenital sinus abnormalities. Prader's classification (which attempts to describe the degree of masculinization) has been used for decades, while the urogenital sinus has generally been described as simply high or low; neither classification fits the spectrum of anomalies, nor do they allow for outcome data research. M...

During vertebrate gastrulation, both mesodermal and endodermal cells internalize through the blastopore beneath the ectoderm. In zebrafish, the internalized mesodermal cells move towards the dorsal side of the gastrula and, at the same time, they extend anteriorly by convergence and extension (C&E) movements. Endodermal cells showing characteristic filopodia then migrate into the inner layer wi...

The classical imaging gold-standard for this diagnosis is the presence of tumor lateral to the carotid artery. Seventeen patients with pituitary macroadenomas with intraoperative confirmation of cavernous sinus invasion were studied with MRI. Only 8 patients had tumor lateral to the carotid artery; 13 had tumor within the carotid syphon and all lacked the ring enhancement of the medial wall of ...

Yolk sac tumor (YST) is a common malignant primitive germ cell tumor that often exhibits differentiation into endodermal structures. They most commonly occur in childhood and adolescence and are rare after the age of 40 years. Derived from the yolk sac during the embryonic period, YSTs can occur in the gonads and germ cells because the tumor cells migrate from the yolk sac toward the gonads. He...
