Concomitant Mycobacterium avium infection and Hodgkin's disease in a lymph node from an HIV-negative child.

We report a case of an immunocompetent child with simultaneously an infection with Mycobacterium avium and Hodgkin's disease in a cervical lymph node. A positive PCR result for M. avium on a biopsy of the lymph node directed the definitive diagnosis for both etiologies and avoided a possible dissemination of this infection after chemotherapy was started.
