Unmasking immune reconstitution inflammatory syndrome: a report of tuberculous epididymo-orchitis mimicking a testicular tumour in a Caucasian AIDS patient.

Worldwide, it is estimated that 14.8% of all new tuberculosis cases in adults are attributable to HIV infection. Genitourinary tuberculosis is a known complication and is considered to be a severe form of extrapulmonary tuberculosis. Isolated tuberculous epididymo-orchitis is rare. We report a Caucasian HIV-positive heterosexual male with a clinical diagnosis of testicular tumour for which he underwent a right orchidectomy. Tuberculous epididymo-orchitis was confirmed by histology. In this case, all Immune Reconstitution Inflammatory Syndrome (IRIS) criteria were met. We want to convey the message that in HIV-positive patients presenting with testicular swelling, an infective aetiology should be considered. This will increase the possibility of early diagnosis and proper management.
