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.

Tuberculosis (TB) has become a global concern due to its increasing incidence, particularly in immunocompromised patients, closely following the migratory patterns of populations. TB pyomyositis is a rare extrapulmonary manifestation of TB. Its clinical presentation varies and requires a high degree of suspicion for early diagnosis. We present three patients diagnosed with TB pyomyositis: a 46-year-old man with dermatomyositis (DM) and hepatitis B who presented with fever, muscle weakness, and an abscess at the right proximal arm; a 71-year-old immunocompetent male, with a past medical history of tuberculous lymphadenopathy in childhood, who presented with a 2-month history of fever and pain at the right thigh, and a 44-year-old woman with systemic lupus erythematosus (SLE) on prednisone and methotrexate who presented with skin eruption at her thighs mimicking lupus panniculitis. In all three patients, Mycobacterium tuberculosis was identified as the causative agent. The lack of specific signs, the false negative tuberculin skin test in some cases, and the unfamiliarity of many clinicians with this entity can cause diagnostic delays. Prompt diagnosis requires a high index of suspicion especially in immunocompromised patients with fever.
