Toxoplasma gondii infects up to one third of the world's population. A key to the success of T. gondii as a parasite is its ability to persist for the life of its host as bradyzoites within tissue cysts. The glycosylated cyst wall is the key structural feature that facilitates persistence and oral transmission of this parasite. Because most of the antibodies and reagents that recognize the cyst...

BACKGROUND The aim of this study was to report on epithelial posttraumatic iris cyst that was successfully treated with needle aspiration and surgical excision with surrounding iris tissue. CASE REPORT A 30-year-old women was treated for a large fluid-filled cyst in the anterior chamber of the left eye; 25 years before, she had an open globe injury. She observed deterioration of her visual ac...

      Abstract: development of squamous cell carcinoma from sebaceous cyst is uncommon.in this report , we report a77- old female patient who has had a sebaceous cyst for 20 years. The cyst started to grow during the last year. The patient underwent an operation for excision biopsy and The diagnosis was squamous cell carcinoma.

Although cardiac involvement is an infrequent presentation in human hydatidosis, early diagnosis and prompt surgical intervention of cardiac hydatid cyst are of utmost importance for the prevention of potential complications. We report a young female patient who presented with a huge cardiac hydatid cyst and severe heart failure symptoms undergoing successful surgical cyst removal with late fol...

Background: Hydatid cyst is an endemic disease in Iran and many middle eastern countries. The clinical presentation of Echinococcus granulosus infection depends upon the site of the cysts and their size. Small and/or calcified cysts may remain asymptomatic indefinitely. However, symptoms due to mass effect within organs, obstruction of blood or lymphatic flow, or complications such as rupture o...

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...

Toxoplasma gondii is an intracellular parasite that causes chronic infection by the develop‐ ment of bradyzoites housed in tissue cysts, preferably in the muscles and central nervous system. The composition and the function of the cyst wall are still not fully understood. Are T. gondii cysts able to incorporate nutrients through its wall? If so, how would these nutrients be traversed to cross t...
