[Uncommon localization of osteomyelitis].

Group A beta-hemolytic streptococcus (GAS) causes almost 10% of acute hematogenous osteomyelitis (AHOM). These entities are frequently located in long bones (femur, tibia and humerus), and only 6-8% of all AHOM are located in the pelvis. This uncommon localization delays diagnosis and can lead to inappropriate management, with negative effects on outcomes. We present the case of a 6-year-old boy with high fever, pain in the right hip and difficulty in walking due to pelvic AHOM and septic shock caused by GAS. We also provide a review of the literature.
