We present the case of an eight-year-old child who developed a pyomyositis of the internal and external obturator muscles and streptococcal tonsillitis simultaneously. Initially, he only presented pain in the lower left limb and he was diagnosed a contracture of the biceps femoris muscle. A few days after, he began with odynophagia, cutaneous exanthema and fever with tonsillar exudate. However, the pain in the left leg persisted, lower lumbar pain and Lassègue sign appeared, so we underwent a magnetic resonance imaging demonstrating the pyomyositis. We reviewed recently described cases of pyomyositis, and we observed an increase of their incidence in our environment. A comparison is made with other case reviews to identify the clinical symptoms that could help in diagnosing the condition early.
