Differential Diagnosis for Skin Burning and Peeling
- Single most likely diagnosis:
- Sunburn: This is the most common cause of skin burning and peeling, especially after prolonged exposure to the sun without adequate protection. The symptoms typically appear a few hours after sun exposure and can range from mild to severe.
- Other Likely diagnoses:
- Chemical burns: Exposure to harsh chemicals can cause skin irritation, burning, and peeling. This could be due to accidental exposure or improper use of chemical products.
- Allergic contact dermatitis: An allergic reaction to substances like poison ivy, oak, or sumac, or to certain metals or chemicals in personal care products, can lead to skin burning and peeling.
- Insect bites or stings: Certain insect bites or stings can cause an allergic reaction, leading to skin burning, redness, and peeling.
- Eczema (atopic dermatitis): A chronic condition characterized by dry, itchy skin that can sometimes burn and peel, especially if scratched excessively.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.):
- Stevens-Johnson syndrome: A rare but life-threatening condition usually caused by an adverse reaction to medication or infection, characterized by widespread skin burning, peeling, and blistering.
- Toxic epidermal necrolysis (TEN): Similar to Stevens-Johnson syndrome but more severe, with widespread skin necrosis and detachment, often requiring immediate medical attention.
- Sepsis: In severe cases of skin burns or infections, if left untreated, can lead to sepsis, a potentially fatal condition.
- Rare diagnoses:
- Pemphigus: A group of rare skin disorders that cause blistering of the skin and mucous membranes, which can lead to burning and peeling.
- Staphylococcal scalded skin syndrome (SSSS): A rare condition caused by staphylococcal toxins that typically affects infants and young children, leading to widespread skin peeling.
- Autoimmune disorders: Certain autoimmune conditions, such as lupus or rheumatoid arthritis, can sometimes manifest with skin symptoms including burning and peeling, though this is less common.
