Differential Diagnosis for Bullous and Vesicles in Hand and Feet
Single Most Likely Diagnosis
- Contact Dermatitis: This is a common condition that can cause bullous and vesicular lesions on the hands and feet, especially if the individual has been exposed to irritants or allergens. The hands and feet are prone to contact with various substances that can trigger an allergic or irritant reaction.
Other Likely Diagnoses
- Dyshidrotic Eczema (Pompholyx): Characterized by the appearance of small, itchy blisters or vesicles on the palms of the hands or soles of the feet. It's a type of eczema that can be triggered by stress, allergies, or exposure to certain metals.
- Bullous Impetigo: A bacterial infection of the skin that can cause bullae (blisters) and vesicles, often on the hands and feet in children. It's contagious and can spread through direct contact with the lesions.
- Pemphigus Vulgaris: An autoimmune disease that can cause blistering of the skin and mucous membranes. While it's less common, it can present with lesions on the hands and feet, among other areas.
Do Not Miss Diagnoses
- Staphylococcal Scalded Skin Syndrome (SSSS): A serious condition caused by staphylococcal toxins that can lead to widespread blistering and peeling of the skin. It's more common in children but can be life-threatening if not promptly treated.
- Toxic Epidermal Necrolysis (TEN): A severe skin condition usually triggered by medications, leading to widespread skin necrosis and detachment. It's a medical emergency that requires immediate attention.
- Steven-Johnson Syndrome: A rare but serious disorder of the skin and mucous membranes, usually a reaction to medication or infection. It can cause blistering of the skin and mucous membranes and is considered a medical emergency.
Rare Diagnoses
- Epidermolysis Bullosa: A group of genetic conditions that result in fragile skin and blisters. While rare, it's an important consideration in patients with recurrent or severe blistering, especially if present from birth or early childhood.
- Bullous Pemphigoid: An autoimmune disease that causes blistering of the skin. It's more common in older adults and can present with large blisters on various parts of the body, including the hands and feet.
