Abstract
Objective: To report the case of a patient with Good Syndrome, detailing the initial clinical picture, evolution of the disease, treatment performed, as well as laboratory tests and images responsible for its diagnosis. Case Report: A 52-year-old female patient with thymoma diagnosed by imaging after recurrent infectious conditions and successive red blood cell transfusions due to repeated anemia. Surgically treated with thymectomy, the patient had a medullary thymoma at histopathological examination. Obtained temporary resolution of the anemic condition for about one year. She developed anemia and infection again, and some underlying cause of immunodeficiency was raised, with investigation and laboratory diagnosis of hypogammaglobulinemia and opportunistic parvovirus B19 infection. Successfully treated by human immunoglobulin infusions. Final Considerations: few studies debate about Good Syndrome, making it difficult to create therapeutic measures and theoretical basis on the subject.
