777 Ganglion cyst, although its precise etiology is not determined, is generally considered a degeneration of the mucoid connective tissue, collagen in specific, and was reported for the first time by Ledderhose in 1893 [1]. It is a benign soft-tissue tumor that usually appears near joints such as the hand, wrist, or foot. A ganglion cyst of the temporomandibular joint (TMJ) is a rare disease, ...

The organochlorines, dichloro-diphenyl-trichloroethane and polychlorinated biphenyl (PCB) are pervasive environmental contaminants. Results from previous studies have been conflicting regarding the relationship between the internal dose of these organochlorine residues and breast cancer risk. To determine whether these compounds are present in breast cyst fluids and whether cyst fluid and plasm...

BACKGROUND The protozoan parasite Toxoplasma gondii is one of the most widely distributed and successful parasites. Toxoplasma gondii alters rodent behavior such that infected rodents reverse their fear of cat odor, and indeed are attracted rather than repelled by feline urine. The location of the parasite encysted in the brain may influence this behavior. However, most studies are based on the...

hydatid disease is a term used to refer infection with the methacestode of echinococcus granulosus parasite in humans, and echinococcusis is restricted to infection with the adult stage in carnivores.glutathione s-transferase (gst) represents the major class of detoxification enzymes from helminth parasites such as echinococcus protoscoleces (psc) and it is candidate for chemotherapeutic and va...

This report describes a case of dermoid cyst localized subcutaneously in the abdominal region, 2 cm to the right of linea alba in a six-year-old, neutered male Persian cat admitted with complaints of painful defecation and abdominal licking. A laparatomy was performed and the mass was seen to have penetrated the periton and extended into the abdominal space with a stalk located among the abdomi...

Introduction: Toxoplasmosis is a widely prevalent zoonotic disease, caused by T. gondii. Chickens, consumed widely in many countries, are considered as one of the most important hosts in the epidemiology of T. gondii infection because they could be a main source of infection for both cats and humans. There was no information regarding T. gondii infection in chickens in this area, therefore, thi...

Hydatid cyst of heart is a rare but potentially fatal site of pathology, especially left ventricular free wall. We managed a successful surgical treatment on a case of a 24 year old man who had a giant cardiac hydatid cyst (71 x 64 mm) that ruptured left ventricular free wall. The cyst was excised gently and all the cystic materials were removed, the cyst cavity was closed with GORE-TEX soft ti...

A three-and-a-half year-old female Rahmani ewe was presented suffering from nervous symptoms. Grossly, a large cyst measuring 7 × 4 cm and weighing 145 g occupied the dilated left lateral ventricle. The overlying cerebral tissue was thin, atrophied and congested. It tore easily, and the cyst was evacuated spontaneously. Microscopically, liquefactive necrosis surrounded by aggregations of macrop...

. The eruption cyst is regarded as a soft tissue analogue of the dentigerous cyst, but is considered as a distinct clinical entity. It is defined as a cyst that lies superficial to the crown of an erupting tooth, and is lined by stratified squamous non-keratinizing epithelium. Clinically, it appears as a soft, often translucent swelling of the gingival mucosa overlying the crown of the involved...
