L49.4

Clinical Causes: Severe skin reactions caused by medications (such as antibiotics, anticonvulsants, or NSAIDs) Infections leading to skin inflammation, including certain viral or bacterial infections Autoimmune diseases like Stevens-Johnson syndrome or toxic epidermal necrolysis Vigorous physical or chemical skin injuries Exposure to harsh environmental factors or allergens Underlying dermatological conditions that can become exacerbated

Key Symptoms: Extensive skin redness and inflammation Widespread skin peeling or exfoliation over 40-49% of body surface Pain or tenderness in affected areas Swelling or blistering of the skin Mild to severe discomfort or itching Possible presence of skin infections due to compromised skin barrier Fever or malaise in some cases

Diagnosis Path: The diagnosis of this condition involves a thorough clinical examination by a healthcare professional, focusing on the extent and appearance of skin involvement. Medical history might include recent medication use, infections, or exposure to potential allergens. Additional tests such as skin biopsies, blood work, or cultures may be performed to identify underlying causes or rule out other conditions. Imaging studies are generally not necessary unless complications arise.

Treatment Protocols: Immediate discontinuation of any suspected causative medications Supportive care with hydration and wound care Use of corticosteroids or other anti-inflammatory medications under medical supervision Application of topical emollients or skin barriers to reduce discomfort Antibiotics or antiviral medications if an infection is present Close monitoring for signs of complications such as infections or fluid loss In severe cases, hospitalization may be required for intensive supportive care
