We evaluated the morphological and functional features of hepatic cyst epithelium in adult autosomal dominant polycystic kidney disease (ADPKD). In six ADPKD patients, we investigated the morphology of cyst epithelium apical surface by scanning electron microscopy and the expression of estrogen receptors (ERs), insulin-like growth factor 1 (IGF1), IGF1 receptors (IGF1-R), growth hormone recepto...

Context Carcinoembryonic antigen analysis of pancreatic cyst fluid is the tumor marker of choice for preoperatively differentiating mucinous from non-mucinous cystic lesions. Objective We aim to determine the most accurate cyst carcinoembryonic antigen cut-off value for distinguishing mucinous cysts from non-mucinous cysts with a focus on discriminating intraductal papillary mucinous neoplasms....

BACKGROUND Vitreous cysts are rare clinical findings and seldom cause visual disturbance. They are generally classified as congenital or acquired and are considered idiopathic when the etiology can not be determined. A previous electron microscopic observation on an idiopathic pigmented vitreous cyst has confirmed its pigment epithelial origin. However, the specific kind of pigment epithelium i...

1. Cyst walls of the beet cyst-nematode (Heterodera schachtii Schmidt) were obtained by sieving a suspension of crushed cysts; about 15mg of dried cyst walls was obtained from 1000 cysts. 2. The cyst walls contained 68% protein calculated from nitrogen content. Glutamic acid, glycine, proline and hydroxyproline made up about 54% by weight of the amino acids obtained on acid hydrolysis. 3. Minor...

Esophageal duplication cyst (EDC) is a congenital malformation of the posterior primitive foregut, which mainly occurs in the thoracic esophagus. Here, we describe a 3-year-old Han Chinese boy afflicted with intermittent fever of acute onset and dry cough. Thoracic computed tomography revealed an 10 cm × 5.4 cm × 5.8 cm oval-shaped, cyst-like tumor located in the extrapleural space, extending a...

BACKGROUND AND OBJECTIVES Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary kidney disease and has important clinical manifestations in childhood. Numerous studies have documented the superiority of magnetic resonance imaging (MRI) for serial monitoring of kidney and cyst volume in this condition in adults. However, no studies have examined the utility of MRI fo...

52 INTRODUCTION Epithelial inclusion or epidermoid cyst (EIC) lined by well defined stratified squamous epithelium enlarges by cellular proliferation and by desquamation of keratinized debris into the cavity of the cyst (1). Histologically, it is differentiated from the dermoid cyst by the absence of dermal structures and from the benign cystic teratoma or true dermoid cyst, which is a neoplasm...

The mandibular infected buccal cyst or mandibular bifurcation cyst is a cystic lesion that occurs on the buccal surface of the permanent mandibular first or second molar in children aged around 6-8 years. We report the clinical, radiographic, and histological features and the treatment of a mandibular infected buccal cyst of the first molar in a 7-year old child. 1 year follow up after the enuc...

Although it is frequent to see hydatid cyst patients in endemic areas, intrabiliary rupture of hydatid cyst in children is rare. Intrabiliary rupture was first reported in 1928 by Dew (1). Intrabiliary rupture is a serious complication of hepatic hydatid cyst. The incidence varies from 1% to 25% in adult patients (2). Rupture of the hydatid cyst into the bile ducts is a rare condition in childr...

This report presents a case of fourth ventricle neurenteric cyst (NE cyst) mimicking hemangioblastoma, which developed in a 50-year-old woman. A tiny enhancing mural portion of the fourth ventricle in MRI suggested that the cyst was hemangioblastoma, but pathological evidence showed that the cyst was in fact NE cyst in the fourth ventricle. In order to make proper decision on to what extent of ...
