Description
Rundong Zhang and colleagues set a 2026 diagnostic quiz built around a man in his seventies with fast-growing, painful plaques. The sores spread over his nose, scalp, and the area around one eye within a month. They broke down tissue, caused fever, and did not improve with drugs against bacteria or fungi.
Readers are asked to pick among four possible diagnoses from the biopsy and test results. Skin samples showed dense clusters of neutrophils, a type of white blood cell, with no sign of infection. The answer given is pyoderma gangrenosum, a rare skin disease driven by immune inflammation. Steroid drugs plus cyclosporine brought quick improvement, which supported the answer.
