Abstract
Soft tissue eosinophilic granulomatosis (Kimura's disease) is an eosinophilic granuloma with a proliferation of lymphoid follicles in the subcutaneous soft tissue. Although no established treatment exists, it is considered a disease with a good prognosis. On the other hand, bacteremia caused by group G hemolytic streptococcus (GGS) is said to be caused by chronic local lymph abnormalities and is likely to recur. We present the case of a 41-year-old Japanese man. He had a history of treatment for Kimura's disease and sepsis due to hemolytic streptococcus and came to our hospital with a chief complaint of fever. His blood culture revealed hemolytic streptococcus, and he was admitted to the hospital. Kimura's disease involves the proliferation of lymphoid follicles, so when blood cultures repeatedly turn positive, it is important to treat the patient with a GGS infection in mind.
