Abstract

Background: Chickenpox is a viral disease that is both benign and self-limiting and is known for its appearance of skin rashes. The presence of musculoskeletal complications, such as septic arthritis and osteomyelitis, is uncommon. Clinicians must be aware of bone pain complaints throughout the disease progression, and also they should pay attention to the potential manifestations of septic arthritis. Timely diagnosis and appropriate antibiotic prescription can be crucial as they can prevent surgical interventions and reduce their risks.

Case presentation: A 6-year-old boy with varicella zoster was referred to the hospital with swelling, pain, and redness of the right groin. The patient was unable to stand. For the past 9 days, papulovesicular lesions were spread over his body, and when he went to the hospital, all the lesions had crusted over. Pain and swelling of the joint and limitation of hip joint movement, along with examination of synovial fluid and increased inflammatory markers such as ESR, CRP, and leukocytosis, led to the diagnosis of septic arthritis. In this case, septic arthritis and cellulitis of the thigh, which both presented as septic shock, occurred simultaneously.

Conclusion: In cases of chicken pox-associated arthritis, even in immunocompetent individuals, severe septic arthritis should be considered as a possible complication. To prevent severe complications associated with septic arthritis, early diagnosis and timely initiation of appropriate management are crucial.
