The fine structure of the mouse tracheal epithelium from the fetal period to the stage of old age was examined with electron and light microscopes. The tracheal epithelium of the adult mouse is ciliated and single columnar in shape, consisting of three kinds of cells: ciliated, non-ciliated and basal. Neither goblet nor brush cells were found. The earliest signs of the cytodifferentiation of ci...

The patient was a 59-year-old woman in whom computed tomography revealed a posterior mediastinal cyst and ovarian cystoma at a medical check-up in March 2007. Blood tests showed high CA19-9 and CA125 levels. She underwent left adnexectomy for ovarian cystoma in July 2008 and histopathological examination led to a diagnosis of dermoid cyst. The postoperative levels of CA19-9 and CA125 remained h...

Ciliated hepatic foregut cyst (CHFC) is a rare lesion which originates from detached hepatic diverticulum or from detachment and migration of buds from the esophageal and bronchial regions of the foregut which subsequently get entrapped by the liver during the early embryonic development of the foregut. CHFCs are mostly seen in adults and are rarely reported in children, with only about 10 case...

The objective of the study was to describe clinical, imaging, surgical and histological findings in a dog with Rathke's cleft cyst pituitary gland. A 6-year-old, female, neutered Staffordshire bull terrier presented an acute onset abnormal behaviour. Magnetic resonance imaging skull showed mass 12.9 mm (height) × 8.8 (width) 10.2 (length) height/brain area value 0.73 (reference <0.31). were sug...

Ciliated hepatic foregut cysts (CHFC) are rare, typically benign, lesions whose incidence has been increasing recently. Despite this increase in incidence, they remain rare and several key characteristics remain poorly understood, including the range of presentation and the risk of malignant conversion. To better understand CHFC, an extensive review of the international literature was performed...
