BACKGROUND Lumps arising in the head and neck constitute an important diagnostic category in children. As malignancy in this age group is relatively rare, lumps that are not due to inflammatory or infective causes often prove to be cysts. Correct diagnoses of the different subcutaneous lumps are often missed because of the lack of recognition or uncertainty with management. OBJECTIVES The pur...

Results 31.1% of cases were intact cysts and 68, 9% were complicated cysts. 34, 8% of intervened cases had complications, mainly air leakage (>7 days) but there were not fatal cases. The cases with preoperative complicated cysts had postoperative complications 1.6 times more than for cases with simple cysts but there is no statistical significance. The mean number of the hospitalized days for c...

The maxillofacial region is affected by a greater number of cysts than any other part of the body. In this study, 90 odontogenic cysts were collected from 90 patients over a five-year period. Patients with radicular cysts, dentigerous cysts and odontogenic keratocysts were further analyzed with regard to age, sex and anatomical distribution. Using the histological classification of the World He...

Seven cases of neonatal ovarian cysts that presented over the past seven years were studied. Complications included torsion and rupture and usually occurred in cysts more than 5 cm in diameter. Surgical removal, either oophorectomy or cystectomy, was the treatment of choice. Because even cystectomy results in loss of normal ovarian tissue, and because spontaneous regression of cysts less than 5...

Artemia has been widely used in aquaculture as a suitable live food. The presence of highly unsaturated fatty acids is a key factor that determines the nutritional value and marketing of Artemia for shrimp, marine larvae, sturgeon and ornamental fish industries. To determine the variation in nutritional content in cysts, decapsulated cysts and nauplii of Artemia from three different biotopes of...

OBJECTIVES The aim of the present study was to analyze the antenatal and postnatal outcome of fetal ovarian cysts in relation to their ultrasonographic pattern and size. METHODS Sixteen fetal ovarian cysts were diagnosed in 16 fetuses and followed with serial ultrasonograms in utero and after birth until spontaneous or surgical resolution. RESULTS Eleven fetal ovarian cysts were simple cyst...

Background: Splenic cysts are rare in all age groups and there are a few reports in the world literature. Primary cysts occur most frequently in children and young adults, comprising around 25% of all nonparasitic splenic cysts. Various techniques are suggested for the treatment of splenic cysts. In this case report, a huge epithelial splenic cyst in a 17-year-old female is presented and differ...

BACKGROUND & OBJECTIVES Odontogenic cysts are among the most frequent destructive lesions of jaws which their pathogenesis and growth mechanism are not cleared. With respect to different roles of mast cells, they may play a role in the pathogenesis and growth of odontogenic cysts. The aim of present study was to evaluate mast cells in the most common odontogenic cyst. METHODS Thirty paraffin-...
