Abstract
Objective: To describe the main characteristics of chylothorax related to non-Hodgkin's lymphoma through a case report. Case Report: This is a case report of a female patient, already diagnosed with follicular non-Hodgkin's lymphoma, admitted with symptoms of malnutrition, weight loss and dyspnea, showing homogeneous pulmonary opacity to bilateral middle third and obliteration of both costophrenic sinuses due to chylothorax-type pleural effusion. As the thoracic duct is responsible for taking lymph rich in nutrients, fats and lymphocytes to venous circulation and, being injured, the patient is suffering from malnutrition, weight loss and changes in immunity, some of the complaints that led the patient in question to seek medical attention. This patient responded to non-invasive clinical measures, without the need for surgical procedures, but there are several interventions for the treatment of chylothorax. Clinical treatment is preferable over surgical treatment because it has a longer hospital stay, morbidity and mortality. Final considerations: The publications raised in the reported case describe the main characteristics related to chylothorax and non-Hodgkin's lymphoma, since this is a type of non-traumatic neoplasm that often generates fistulization of the thoracic duct and, as a result, causes chylothorax.
