Case Report : A Rare Cause of Retroperitoneal Fibrosis Responding to Steroids
Introduction:
Retroperitoneal fibrosis is a rare inflammatory disease. Neuroendocrine tumors are a heterogenous group that arise from enterochromaffin cells, most commonly in the gastrointestinal tract. Their capacity to secrete hormones, five HT, tachykinins etc, are responsible for symptoms known as carcinoid syndrome. However NETS, particularly arising from the midgut, can cause fibrosis. This can result in bowel obstruction, but also cause fibrosis in the retroperitoneum, lungs and cardiac valvular fibrosis.

Coexistence of a Somatostatin-Producing Carcinoma of Duodenum and a Jejuna Gastrointestinal Stromal Tumor (GIST) in a Patient with Von Recklinghausen’s Disease
Introduction:
Duodenal neuroendocrine tumors comprise 2-3% of all neuroendocrine tumors of the gastrointestinal tract. Coexistence of NF-1, NET and GIST is rare and only five cases have been described in the literature.

Atypical lung carcinoid tumor metastatic to endocrine glands and bone marrow
Introduction:
Bronchopulmonary neuroendocrine tumors (BP-NETs) comprise 20% of all lung cancers. Typical low grade carcinoid tumors (TC) represent the majority of BP-carcinoids. Intermediate grade atypical carcinoid tumors (AC) are less often encountered but more aggressive. Although metastatic dissemination to mediastinal lymph nodes, liver, skeleton and central nervous system (CNS) is common, involvement of the endocrine glands has rarely been reported.
