introduction: primary gastric lymphoma (pgl) is a rare tumor, whose differential diagnosis may become complicated without precise immunohistochemistry (ihc) and genetic analysis. case presentation: a 33-year-old woman presented with gastric cancer and had undergone gastrectomy without precise ihc and staging in another center. inappropriate ihc after surgery showed diffuse large b-cell lymphoma...

Primary breast lymphoma represents less than 1% of all primary breast malignancies and most primary breast lymphomas are of B-Cell origin. The association of anaplastic lymphoma kinase (ALK) negative anaplastic large cell lymphoma (ALCL), a very rare form of primary breast lymphoma, with silicone-filled breast implants has been suggested and several case reports supported this proposal, especia...

A 65-year-old man with no significant past medical history was admitted to an outside hospital with 1.5 months of crampy, lower abdominal pain associated with rectal urgency and tenesmus. Initial computed tomography showed thickening of his rectosigmoid and mid to distal descending colon; follow-up colonoscopy revealed inflammation of the affected areas with focal lamina propria vascular conges...

in this study, a 2.5-year-old boy suffering from a febrile seizure with normal laboratory tests and a history of immune hemolytic anemia was examined. brain mri demonstrated some tumors in the frontal, parietal, and occipital lobe that corroborated the pathology results of primary central nervous system lymphoma for the patient. the patient was treated with high- dose of methotrexate. our resul...

Introduction/Background It is essential to perform a detailed preoperative description of disease’s extension which can improve patient management, including work-up, operative time and postoperative care. Ultrasound (US) reliable method for differentiation between benign malignant adnexal tumors local staging endometrial cervical cancers. Few studies have pointed the use US evaluating...

Classically, the HIV/AIDS-related lymphomas are of the B cell type and involve the central nervous system and the abdominal cavity. Primary maxillary sinus lymphoma is rare. Plasmablastic lymphoma (PBL) is an aggressive form of non-Hodgkinvs lymphoma, and is extremely rare. Here we present a case of plasmablastic lymphoma with primary site being maxillary sinus, a rare location.

Gastrointestinal xanthomas are characterized by foamy cytoplasmic cells containing lipid in lamina propria, and occur almost in the gastric mucosa. Colonic xanthomas have been described in rare case. All reported colonic xanthomas were located in rectosigmoid. Rectosigmoid xanthomas have tended to exhibit small polypoid lesion, on the contrary flat in stomach. We report a case of xanthoma on as...

Primary bone lymphoma is an uncommon tumour accounting for approximately 4-5% of extra nodal lymphoma and less than 1% of all Non-Hodgkin's lymphoma. The radiographic appearance of primary bone lymphoma is variable. As lesions frequently resemble other disease processes namely chronic osteomyelitis and metastases, further imaging evaluation and histopathological examination allow early identifi...

The primary ovarian lymphoma is a rare disease with poor prognosis. The incidence of autoimmune hemolytic anemia in patients with non-Hodgkin's lymphoma is estimated at 3%. However, a substantial portion of the previously reported cases of ovarian lymphoma actually represented ovarian involvement by more diffuse lymphomatous process. If stringent criteria are used for case selection, true prima...
