He also had hemorrhagic nasal drainage and was diagnosed with sinusitis two weeks ago. He was again treated by various antibiotics with no clinical benefit for this complaint. Additionally, he had arthralgia affecting both knees. His medical history revealed that he had hypertension and diabetes and was using metformin and gliclazide. He never smoked. His family history was unremarkable. Dermatological examination showed erythema, swelling and tenderness of the right ear (Figure 1). Needle aspiration revealed no drainage or suppuration. There was also conjunctival hyperemia in his left eye (Figure 2). Laboratory examinations demonstrated a white blood cell count of 13200 /µL (with an increased neutrophil ratio of 71.8% and decreased lymphocyte ratio of 19.5%), a sedimentation rate of 82 mm/hr, and a C-reactive protein value of 72.0 mg/L. Test results for ANA, ANCA and HLA-B27 were all negative. His chest X-ray revealed an increased bronchial shadow and this was nonspecific (Figure 3). Histopathological examination of a punch biopsy specimen obtained from the right ear revealed a predominantly lymphocytic inflammatory cellular infiltrate in the subcutaneous tissue and cartilage.
