Most abdominal masses in the pediatric population derive from ovaries. Ovarian can occur all ages, although their incidence, clinical presentation and histological distribution vary among different age groups. Children adolescents may develop non-neoplastic ovarian lesions, such as functional cysts, endometrioma, torsion, abscess lymphangioma well neoplasms, which are divided into germ cell, ep...

The spectrum of ovarian pathologies embraces wide age range among females because the risk developing lesion starts from birth and follows diverse patterns through-out life.1,2 rate development complications, recurrence, progression to malignancy, morbidity mortality, also varies according presentation various pathologies.3,4,5 prevalence cystic lesions ovary is more in reproductive group as co...

Tumors of the small bowel are uncommon, representing 3-6% of all gastrointestinal neoplasms. Less than 30% of these tumors are located in duodenal region. Gastrointestinal schwannomas are extremely rare neoplasms accounting for less than 1% of all neoplasms of the gastrointestinal tract.[1] Most of the schwannomas are benign tumors. Hemorrhage and bowel obstruction are the most common presentin...

CONTEXT Greater utilization of cross-sectional abdominal imaging has increased the diagnostic frequency of cystic neoplasms of the pancreas. The "International Consensus Guidelines 2012 for the Management of IPMN and MCN of the Pancreas" illustrates a diagnostic and therapeutic algorithm for these lesions based on current knowledge. CASE REPORT We present a case of a 49-year-old woman with tw...

In recent years a number of reports have indi cated that nitrogen mustard exerts a greater effect in certain human neoplasms when admin istered intra-arterially than when given by the conventional route of injection (1, 2, 3, 11-13). Intra-arterial treatment was originally considered of value primarily in neoplasms confined to the extremities or head. Maxfield and his associates have recently t...

Low-grade appendiceal mucinous neoplasms (LAMNs) are rare tumors that primarily diagnosed using computed tomography(CT) enhancement and magnetic resonance imaging (MRI). Herein, we report the sonographic features, especially for contrast-enhanced ultrasound (CEUS), of a 70-year-old female with an unusual LAMN metastasizing to peritoneum spleen. The patient had right pelvic mass 2 days prior pre...

Gastrointestinal stromal tumors (GIST) are uncommon mesenchymal spindle-cell or epithelioid neoplasms, located mainly with higher frequency in the stomach and small bowel. GISTs represent the majority of primary non-epithelial neoplasms of the digestive tract, most frequently expressing the KIT protein a transmembrane tyrosine kinase receptor for stem cell factor. Extra-gastrointestinal stromal...

Renal neoplasms with induction times ranging from 218 to 505 days appeared in 51 or 64% of 80 male Wistar rats in 3 groups which, when 1 or 7 days old, were given single s.c. injections of dimethylnitrosamine in dosages of 125 ;ug/animal or 10 mg/kg. In 44 male rats so treated after weaning at 21 or 70 days of age, tumor yields were scant and induction times exceeded 480 days, but dimethylnitro...

INTRODUCTION It is rare for primary tumors to arise from the mesentery. Lymphangiomas appear as congenital malformations of the lymphatic system or benign neoplasms as a large, thin-walled, often multilocular cyst. Mesenteric infiltration is common and during surgical treatment, adjustment of structures such as the bowel and resection of the spleen may be required. Cystic mesotheliomas are rare...

BACKGROUND Mucinous cystic neoplasms arise in the ovary and various extra-ovarian sites. While their pathogenesis remains conjectural, their similarities suggest a common pathway of development. There have been rare reports involving the mesentery as a primary tumour site. CASE PRESENTATION A cystic mass of uncertain origin was demonstrated radiologically in a 22 year old female with chronic ...
