[Sarcoidosis-lymphoma syndrome].

Sarcoidosis may occur in association with lymphoma (sarcoidosis-lymphoma syndrome), it is an uncommon but well-known association. Some clinical features can be similar and clinicians have the challenge to differentiate between these two diseases or prove their co-existence. Clinical and laboratory data are not characteristic in any of them, and an anatomopathological study of lymphadenopathy is necessary to establish the diagnosis. The sarcoidosis-lymphoma syndrome could occur as a result of a disturbance in the host immune system in sarcoidosis and in some patients with solid tumors or hematologic malignancies who have received chemotherapy. We present a case report of a patient with sarcoidosis-lymphoma syndrome.
