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 re...

Background:Primary malignant lymphoma of the uterine cervix is extremely rare and can be misdiagnosed due to its different clinical presentations. The aim of this report was to introduce a case of primary malignant lymphoma of the uterine cervix which was misdiagnosed as an ovarian cyst on ultrasonography. Case report: A 31-year-old female referred with a...

Primary immunodeficiency disorders can predispose to certain malignancies but hitherto no such relation has been established for X-linked agammaglobulinaemia (XLA). We have diagnosed rapidly progressive colorectal cancer in 3 unrelated young adults with XLA. We could find no explanation for the tumours. Since the calculated incidence of rectosigmoid cancer is increased 30-fold in patients with ...

Primary retroperitoneal malignant lymphoma is rare, and primary retroperitoneal indolent B-cell lymphoma has not been reported. A 64-year-old woman presented anuria. Imaging techniques showed large retroperitoneal mass, and biopsies from it revealed non-Hodgkin indolent B-cell lymphoma (small lymphocytic lymphoma/chronic lymphocytic lymphoma). The tumor appeared retroperitoneal primary and extr...

156 Iranian patients with primary malignant tumors of the small intestine were reviewed. Malignant lymphoma was the most common tumor type, comprising 128 patients (82%), followed by adenocarcinoma (22 patients, 14.1 %), leiomyosarcoma (4 patients, 2.56%) and carcinoid tumor (2 patients, 1.28%). Lymphomas and adenocarcinomas were primarily located in the duodenum or jejunum, whereas leiomy...

Primary central nervous system (CNS) lymphoma is a rare form of non-Hodgkin's lymphoma. The clinical presentation is variable, depending on its localisation within the nervous system. Only 1% of primary CNS lymphoma emerges in the spinal cord, and the prevalence of primary lymphoma of the cauda equina is unknown, but probably even rarer. Diagnosing primary lymphoma of the cauda equina is diffic...

Clinicopathologic information of gastrointestinal (GI) lymphoma in Southeast Asia is lacking. A retrospective analysis of 120 cases of GI lymphoma in Thailand diagnosed at Siriraj Hospital based on WHO classification was performed. All were non-Hodgkin lymphoma (NHL). The peak age was in the sixth and seventh decades; a slight male preponderance was observed. Sites of involvement included stoma...

INTRODUCTION In this study, we investigated radiological changes in the sigmoid colon in chagasic patients by comparing their colon lengths and caliber with those of non-chagasic living in the same region and non-chagasic living at high altitudes. METHODS A total of 317 individuals were evaluated using clinical, serological and radiological methods and divided into three groups: 1) one hundre...
