Pyomyositis in an HIV-positive premature infant: case report and review of the literature.

Abstract

Pyomyositis is a purulent infection of skeletal muscle caused predominantly by Staphylococcus aureus. Although not often encountered in the continental United States, pyomyositis is frequently seen in tropical areas. Pyomyositis is difficult to diagnose as it may mimic other diseases. Delay in diagnosis may lead to septicemia, shock, and death. Recently, two cases of patients with pyomyositis and acquired immune deficiency syndrome were reported. We report a case of pyomyositis in a 7-week-old premature infant who subsequently tested positive for anti-HIV antibodies. A brief review of the topic is included.
