introduction paragangliomas are mostly localized in the adrenal medulla and they are usually pheochromocytomas, derived from the neural crest, but otherwise mesenteric paragangliomas are extremely rare tumors. case presentation in this article we represent a 59-year-old female with an abdominal mass and pain due to mesenteric paraganglioma. conclusions paragangliomas can occur as mesenteric tum...

background: tumors of the central nervous system (cns) are a heterogeneous group of neoplasms with different prevalence in different sex and age groups and various parts of cns. objectives: determining the relative frequency of different types of cns tumors in different ages, sex and cns anatomical locations. materials and methods: this retrospective study was performed using pathological repor...

The rectum and appendix are the two major sites of well-differentiated endocrine neoplasms (carcinoid tumors) in the lower gastrointestinal tract. Previously, we reported the consistent expression of peripherin in rectal well-differentiated endocrine neoplasms without metastases. However, its expression has not as yet been examined in appendiceal well-differentiated endocrine neoplasms. The aim...

With the exception of lymphoma involving the spleen, other primary and secondary neoplasms are rare and infrequently encountered. Primary malignant neoplasms involving the spleen are lymphoma and angiosarcoma. Primary benign neoplasms involving the spleen include hemangioma, lymphangioma, littoral cell angioma and splenic cyst and solid lesions such as hamartoma and inflammatory pseudotumor.

Pituitary tumors are relatively common intracellular neoplasms, and constitute 10-15% of all intracial neoplasms. These types often have difficulties not infrequent recurrence, even though surgery has been done. Although there many studies on pituitary tumors, the pathogenesis occurrence these is entirely clear. It generally considered that neoplasms primary tumors. Biomolecular electrons show ...

This review illustrates a wide spectrum of gastric neoplasms with emphasis on imaging findings helpful in characterizing various gastric neoplasms. Both the malignant and benign neoplasms along with focal gastric masses mimicking tumour are illustrated. Moreover, imaging clues to reach an accurate diagnosis are emphasized.

A variety of neoplasms can develop in each fetal organ. Most fetal neoplasms can be detected by careful prenatal ultrasonographic examination. Some neoplasms show specific ultrasonographic findings suggesting the differential diagnosis, but others do not. Knowledge of the presence of a neoplasm in the fetus may alter the prenatal management of a pregnancy and the mode of delivery, and facilitat...

A young woman with Li-Fraumeni syndrome (LFS) was referred to our hospital. On examination, multiple flat neoplasms were detected in addition to semi-pedunculated polyps. Restorative proctocolectomy was performed; one submucosal invasive cancer, two mucosal cancers, and several adenomas with high-grade dysplasia were detected. On immunohistochemical staining with p53, every part of all neoplasm...

Cystic pancreatic neoplasms are uncommon, but are being seen more frequently due to the widespread use of crosssectional imaging. In this article, we will address the clinical and imaging features of the more commonly seen neoplasms. Points of differentiation between these neoplasms, the use of cyst fluid analysis and an approach to the incidentally discovered cystic mass will be addressed.
