Question
On the afternoon of May 23, a six-year-old girl developed large red spots below her knees, which have now turned into red blotches, causing no pain or itching. By May 27, the blotches had spread to her thigh, and red spots had even started to appear on her small arm. The girl consulted a dermatology specialist at Youli Hospital in Yili, Xinjiang.
Answer
From the symptoms observed, allergic dermatitis should be considered first, and allergic purpura cannot be ruled out. Immediate action is required to avoid severe consequences. It is recommended to seek medical attention promptly for routine blood tests and regional physical examinations to ensure accurate diagnosis and subsequent medication treatment.
