Pyomyositis is a primary pyogenic muscular infection. It has been originally described in the tropics. Presenting signs and symptoms are not specific. It is frequently misdiagnosed in the early stages. We report the case of a 47-year-old woman with systemic lupus erythematosus treated with corticosteroids who presented a thigh pyomyositis evidenced by echography and MRI. Outcome was uneventful after antibiotics and surgical drainage. Pyomyositis is increasingly described among immunocompromised people, including lupus patients treated with corticosteroids.

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.

Pyogenic sacroiliitis and pyomyositis are uncommon infectious diseases and their diagnoses are often delayed. They are typically seen in children and young adults and are rare in middle-aged people especially in those affected by rheumatic diseases. We present the first case of a Staphylococcus aureus related pyogenic sacroiliitis associated with iliacus and gluteal pyomyositis occurring in a patient with systemic lupus erythematosus. Antibiotic treatment was administered for a total of 6 weeks with a total recovery. Pyogenic sacroiliitis and pyomyositis, although remaining rare events, should be remembered as severe complications in immunosuppressed patients with inflammatory diseases. Early clinical suspicion, imaging diagnosis, and adequate therapy are decisive for the satisfactory outcome.

Pyomyositis (PM) is a common masquerading disease that is frequently misdiagnosed. A concurrent state of immunodeficiency is observed in up to 75% of tropical PM cases. PM in systemic lupus erythaematosus (SLE) is a relatively rare disease. I report a case of PM that was caused byKlebsiella pneumoniaein a patient with SLE who presented with leg pain, fever and a lupus flare-up. The patient was correctly diagnosed using a CT scan. Immediate surgical drainage was performed, and empirical antibiotics were administered. The patient was discharged while in a recovering condition. The clinical features, the results of radiographic investigations and the management of PM in SLE are synopsised in this article to underscore the importance of considering this relatively rare disease during differential diagnosis in patients with SLE with muscle pain with or without fever. I also emphasise the need to exclude mycobacterial infection in patients with SLE with PM.

Pyomyositis is a pyogenic infection of skeletal muscle that arises from hematogenous spread and usually presents with localized abscess. This muscle infection has been rarely reported in adult-onset systemic lupus erythematous and, to the best of our knowledge, has not been diagnosed in pediatric lupus population. Among our childhood-onset systemic lupus erythematous population, including 289 patients, one presented pyomyositis. This patient was diagnosed with childhood-onset systemic lupus erythematous at the age of 10 years-old. After six years, while being treated with prednisone, azathioprine and hydroxychloroquine, she was hospitalized due to a 30-day history of insidious pain in the left thigh and no apparent trauma or fever were reported. Her physical examination showed muscle tenderness and woody induration. Laboratory tests revealed anemia, increased acute phase reactants and normal muscle enzymes. Computer tomography of the left thigh showed collection on the middle third of the vastus intermedius, suggesting purulent stage of pyomyositis. Treatment with broad-spectrum antibiotic was initiated, leading to a complete clinical resolution. In conclusion, we described the first case of pyomyositis during childhood in pediatric lupus population. This report reinforces that the presence of localized muscle pain in immunocompromised patients, even without elevation of muscle enzymes, should raise the suspicion of pyomyositis. A prompt antibiotic therapy is strongly recommended.

A 53 year old-female patient with lupus had undergone a cephalo-medullary nailing for a femur shaft fracture 30 years ago. This was complicated by osteomyelitis, requiring multiple debridement procedures and hardware removal. Recently, she developed a painful soft tissue mass in the same region, which was ultimately diagnosed as pyomyositis. Because of chronic bone changes due to her past history, traditional imaging could not differentiate between osteomyelitis infarction and pseudotumor. A combined indium-labeled leukocyte scan with a technetium-99 sulfur colloid marrow scan ruled out osteomyelitis and guided proper treatment without osseous debridement and thus prevented unnecessary cross-contamination of the bone.
