Tubercular orchitis in a patient with AIDS : Report of a case with fine needle aspiration diagnosis

Although tuberculosis is one of the most common opportunistic infections in AIDS, the testis is rarely involved. Clinically, tubercular orchitis mimics malignancy. Fine needle aspiration (FNA) can be used to distinguish these 2 lesions. A 34-year-old, heterosexual male presented with right scrotal swelling, loss of weight and fever. Clinically, malignancy was suspected. FNA showed a few lymphocytes and neutrophils in a necrotic background. Ziehl-Neelsen staining showed high acid-fast bacillus positivity. Serologic testing for HIV showed seropositivity for HIV I and II antibodies. FNA is a useful modality in differentiating tuberculosis from malignancy. In developing countries, tuberculosis should be considered in cases of unilateral testicular enlargement. To the best of our knowledge, this is the third reported case of AIDS presenting as testicular tuberculosis.
