Mycobacterium avium complex suppurative parotitis in a patient with human immunodeficiency virus infection presenting with immune reconstitution inflammatory syndrome

Restoration of the immune system following initiation of antiretroviral therapy can result in an adverse phenomenon known as immune reconstitution inflammatory syndrome (IRIS). Herein, we report a case of Mycobacterium avium complex (MAC) suppurative parotitis associated with IRIS in a patient with advanced human immunodeficiency virus disease. To the best of our knowledge, this is the first reported case of MAC parotitis in the setting of IRIS and clinicians should be aware of this condition.
