Sclerosing stromal tumor of the ovary is a rare, benign ovarian tumor, seen primarily in young women. We report a 3-year-old girl who presented with a palpable lower abdominal mass. Computed Tomography (CT) study revealed a huge pelvic mass with an enhancement pattern typical of ovarian sclerosing stromal tumor. The diagnosis was confirmed by pathology examination of the surgically resected tum...

Elaborate courtship displays are relatively common features of the masculine reproductive behavior in birds. However, little is known about their neural and hormonal control. One bird that performs such a display is the golden-collared manakin (Manacus vitellinus) of Panamanian forests. Adult males, but not females, perform a physically intense display requiring substantial neuromuscular contro...

Recent morphologic and histogenetic studies provide a basis for the classification of testicular and ovarian tumors of germinal, mesenchymal, and sex cord origin. That gonadal tumors in the male and female are identical and homologous' 44 is attributed to totipotentiality of the cellular components that contribute to the formation of the gonad. Seminoma, embryonal carcinoma, teratoma, and chori...

Peutz-Jeghers syndrome is characterized by multiple polyps throughout the gastrointestinal tract in association with mucocutaneous pigmentation. Although Peutz-Jeghers syndrome polyps are hamartomas, frequent association of this syndrome with both gastrointestinal and non-gastrointestinal tumours had led to reassessment of the cancer risk in this hereditary disorder. The most common gynaecologi...

Aims: Umbilical cord blood (UCB) has been recently considered as an alternative source of hematopoitic progenitor cells for clinical application. The parameters commonly used to evaluate a UCB unit and predict transplant outcomes have been total nucleated cell count (TNCs), CD34+ cells concentration and total volume of cord blood collected. The volume of cord blood collection is also important ...
