Differential Diagnosis for Peeling Skin on Feet
Single Most Likely Diagnosis
- Dry Skin (Xerosis): This is the most common cause of peeling skin on the feet, often due to environmental factors, lack of moisture, or excessive washing.
Other Likely Diagnoses
- Athlete's Foot (Tinea Pedis): A fungal infection that can cause peeling skin, especially between the toes, due to moisture and warmth.
- Eczema (Atopic Dermatitis): A chronic skin condition characterized by itchy, inflamed skin that can peel, especially if not properly managed.
- Psoriasis: An autoimmune condition that can cause thick, scaly, peeling skin patches on various parts of the body, including the feet.
Do Not Miss Diagnoses
- Staphylococcal Scalded Skin Syndrome (SSSS): A serious condition caused by staphylococcal toxins that can lead to widespread skin peeling, more common in children but can occur in adults with significant morbidity.
- Toxic Epidermal Necrolysis (TEN): A life-threatening skin condition usually triggered by medications, leading to widespread skin peeling and detachment.
- Pemphigus: A group of autoimmune diseases that can cause blistering and peeling of the skin, which can be life-threatening if not treated promptly.
Rare Diagnoses
- Keratolysis Exfoliativa: A rare condition characterized by recurrent episodes of peeling skin on the palms and soles, often without an identifiable cause.
- Pityriasis Rubra Pilaris (PRP): A rare skin disorder that can cause constant scaling, peeling, and thickening of the skin, including on the feet.
- Acral Peeling Skin Syndrome: A rare genetic disorder that leads to recurrent peeling of the skin on the hands and feet, starting in infancy or early childhood.
