The most frequent extra-nodal site of lymphoma is gastric lymphoma. The bulk of such lesions are extra nodal marginal zone B mucosal cell lymphoma correlated with lymphoid tissue (MALT) type or diffuse lymphoma of large B cells. We are reporting a case of diffuse major B-Cellular gastric lymphoma, which at first showed indigestion, abdominal heaviness, nausea and widespread weakness with 3-4 months of weight loss. In the antropyloric region and distal portion of lesser curvature of stomach suggestive of aetiology of cancer, the CT abdomen shows circumferential wall thickening. DLBCL has been confirmed by HPE and IHC. The neoplasm entered serosa and was found to have adherence to the pancreatic capsule in stage IIE of gastric lymphoma. Following the staging, treatment with an R-CHOP regimen (rituximab, cyclophosphamide, oncovin (vincristine), hydroxydaunorubicin, and prednisone) was done.

Paragangliomas are tumors of the autonomic nervous system, located extra-adrenally, presenting inside the base of the head, chest and abdomen. They can appear as a primary retroperitoneal neoplasm when viewed inside the abdominal cavity and might resemble as vascular malformations or any other conditions same as retroperitoneal organs particularly such as pancreas, kidney. These are relatively uncommon endocrine tumors that originate from specific tissue of the paraganglion. They synthesise, store and secrete catecholamines, which can contribute to headache, sweating, palpitation and hypertension. These may be mistaken for GISTs with no histological diagnosis and symptoms of catecholamine overload (non functional). We are reporting a case of 42 yrs male with clinical features of slow backache radiating to both lower legs and with the presence of tingling sensation. Corresponding contrast enhanced CT scan shows a para – aortic mass.
