Tropical pyomyositis caused by salmonella within the gluteus maximus of a hepatitis B carrier.

Tropical pyomyositis, a disease often seen in tropical countries, is characterized by suppuration within the skeletal muscles, manifesting as single or multiple abscesses. Staphylococcus aureus is the most common agent responsible for typical pyomyositis. Misdiagnosis usually occurs as a result of nonspecific presentation, unfamiliarity with the disease, and the many possible differential diagnoses. Here we present a rare case of tropical pyomyositis caused by Salmonella (group D non-typhi Salmonella) within the gluteus maximus of a hepatitis B carrier without definite previous gastrointestinal episodes.
