Differential Diagnosis for Resolving Rash with Residual Redness on Palms
- Single most likely diagnosis
- Contact Dermatitis: This is a common condition that can cause a rash on the palms, especially if the individual has been exposed to an allergen or irritant. The residual redness along the perimeters of the palms could be a sign of the rash resolving.
- Other Likely diagnoses
- Dyshidrotic Eczema: A type of eczema that typically affects the palms and soles, characterized by small, itchy blisters. As it resolves, it may leave behind redness.
- Psoriasis: Palmar psoriasis can cause red, scaly patches on the palms. The residual redness could be a sign of the condition resolving or partially treated.
- Pompholyx: Similar to dyshidrotic eczema, it causes blisters on the palms and soles, which can leave redness as they resolve.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Secondary Syphilis: Can cause a rash on the palms and soles, which is a critical diagnosis to consider due to the potential for serious complications if left untreated.
- Lyme Disease: Although less common, Lyme disease can cause a rash that might resemble the described symptoms, and missing this diagnosis could lead to severe health issues.
- Rare diagnoses
- Keratoderma Blennorrhagicum: A rare condition associated with Reiter's syndrome, characterized by a rash on the palms and soles.
- Pityriasis Rubra Pilaris: A rare skin disorder that can cause a rash and redness on various parts of the body, including the palms.
