This 8 year old girl developed upper respiratory symptoms with fever, cough, tachypnea, and malaise several days before a purulent conjunctivitis, erosive oral mucositis, and blistering skin rash. The cutaneous lesions were relatively limited, and the oral lesions and conjunctivitis began to improve 3 to 4 days later. Rapid diagnostic tests for Mycoplasma pneumoniae were positive. Interestingly, her mother had a history of pneumonia treated with oral antibiotics several weeks earlier, and her sister developed a cough and mild but similar rash several days after the patient was hospitalized.
