case_images: A 21-year-man was admitted to our hospital with a 1-week history of multiple joint swelling and pain (both knees, both ankles, the right shoulder, and wrist) and fever, we could observe that significant redness, swelling, and a subcutaneous hematoma in his right ankle joint, and the local skin temperature was elevated (Figure 1). We found that the subcutaneous hematoma was ulcerated and necrotic, so debridement was performed (Figure 1) and wound secretions were taken for culture; the cultures of joint fluid and wound secretions were negative, and the right ankle magnetic resonance imaging (MRI) examination suggested inflammatory arthritis. After admission, he was treated with NSAIDs, sulfasalazine, and intravenous cefuroxime sodium and ornidazole for 2 weeks, which resulted in significant improvement and the patient was discharged; after 1-month follow-up, the symptoms largely disappeared (Figure 1).
