BL has been classified into three subtypes according to the World Health Organization classification: Sporadic type, endemic type and immunodeficiency-associated type. Clinically, patients with BL often present with solid tumors or large lymph nodes or symptoms similar to acute leukemia, and bone marrow invasion is present in more than 25% of cases. Afterward, we reviewed the characteristics of 11 patients with BL involving the stomach, pancreas or spinal cord.īurkitt lymphoma (BL) is a subgroup of high-grade non-Hodgkin’s lymphoma (NHL) with an aggressive clinical course that was first described as a clinical entity in children in Central Africa by Denis Burkitt in 1958. The patient refused chemotherapeutic treatment and died one week later due to upper gastrointestinal hemorrhage. Gastroduodenal endoscopy revealed primary BL with massive involvement of the gastric body and duodenum. Subse quent whole-body positron emission tomography/computed tomography exa mination showed multifocal malignant lesions in the stomach, pancreas, gall bladder, bone, bilateral supraclavicular fossa, anterior mediastinum, bilateral axillary and retroperitoneal lymph nodes. Additionally, we observed abnormally thickened lesions of the gastric wall, multiple enlarged retroperitoneal lymph nodes and a well-demarcated, posterolateral extradural mass lesion between T9 and T12, with extension through the spinal foramen and definite bony destruction, suggesting metastasis in gastric malignancy. Magnetic resonance imaging of the abdomen and lumbar spine showed a swollen pancreas and gallbladder, with peripancreatic exudation and liquid collection, indicating acute pancreatitis and acute cholecystitis. A 53-year-old man was referred to our hospital from the local county hospital due to abdominal pain for two weeks and weakness in the lower extremities for one day.
