“…The clinical features of the reported GAS pyomyositis cases are summarized in Table 2 [5, 9–27]. Many of these cases occurred in temperate climates (20/24, 83.3%), and most patients were children or young adults, with relatively few middle-aged patients (mean age, 30.3 ± 21.0 years).…”

“…Furthermore, GAS infection is a known complication of chicken pox in children [5], although only 1 of the 6 pediatric cases was GAS-positive. Although pyomyositis typically occurs in the lower extremities (9/24, 37.5%) [5, 9–27], other muscle groups can be involved, such as the iliac [10], psoas [11, 17], iliopsoas [11], trunk [5], neck [13, 18, 26, 27], and upper extremity muscles [14, 16, 19, 22, 25]. Involvement of multiple muscle groups is also common (9/24, 37.5%).…”

BackgroundPyomyositis is typically caused by Staphylococcus aureus, and is rare in temperate climates, although its prevalence has been recently increasing. This infection often involves the thigh, and is associated with immunodeficiency.Case presentationWe report the case of a healthy 20-year-old Japanese woman who experienced a fever and continuous pain for several days. She was admitted to our hospital and was diagnosed with pyomyositis after we discovered an abscess between the muscles of her dorsal distal left thigh using computed tomography. This is a rare case of thigh pyomyositis, as it was caused by group A streptococcus and occurred in an immunocompetent adult from a temperate climate.ConclusionsOur review of the literature revealed that group A streptococcus pyomyositis typically occurs in temperate climates, among young adults without any underlying disease, and is associated with a poorer prognosis, compared to general pyomyositis. We suggest that pyomyositis should be considered when immunocompetent adults present with apparently idiopathic inflammatory muscle lesions.
