Cortical follicle atrophy

Cortical follicular atrophy is one of the clinical symptoms of pathological anatomy in patients with bullous epidermal necrosis and drug release rash. This is a type of drug rash we first saw in China in 1958. It is relatively rare in clinical practice, but it is quite serious. Sudden onset, rash spread throughout the body within 2 to 3 days. Initially bright red or purple-red spots. Sometimes it is polymorphous erythema at the time of onset, and then it increases and expands, fused into large brown-red patches. It is a clinical manifestation of drug allergy.
