Abstract
Septic arthritis caused by M. hominis is exceptionally rare. Here, we report on a 62-year-old man with a medical history of gout and renal cell carcinoma who presented with persistent knee pain and swelling following partial nephrectomy complicated by an abdominal abscess. Arthrocentesis revealed monosodium urate crystals, leading to the initial diagnosis and treatment of gouty arthritis using intra-articular steroid injections, allopurinol, and colchicine. Initial cultures yielded no growth. However, faint transparent colonies grew after discharge, which were eventually identified as M. hominis. Initial antibacterial therapy targeting suspect Mycoplasma spp. was begun with doxycycline, and the patient ultimately completed 12 weeks of doxycycline and clindamycin with cure. This case underscores the importance of maintaining clinical suspicion for fastidious organisms when faced with persistent clinical symptoms without an identifiable organism and highlights a rare clinical presentation of M. hominis.
