A Case of Anaplastic Large Cell Lymphoma of the Mesentery Complicated by Systemic Inflammatory Response Syndrome

Abstract

A 66-year-old woman was admitted because of an abdominal mass with systemic inflammatory response syndrome. We decided to perform emergent resection surgery to confirm the diagnosis and provide treatment as appropriate. As the tumor was located in the root of the jejunal mesentery, we performed partial jejunectomy with the tumor. Pathological examination revealed that the tumor was an anaplastic large cell lymphoma that was anaplastic lymphoma kinase-negative. After the operation, the patient's general condition improved and the laboratory data promptly returned to normal. Three months after the surgery, hilar lymph node, abdominal lymph node, inguinal lymph node metastases, as also lung metastasis appeared. Chemotherapy with eight cycles of CHOP was administered, and at present, four years later, the patient is still doing well.
