Differential Diagnosis for Rosacea-like Pregnancy Rash
- Single most likely diagnosis
- Pregnancy-associated pruritic rash: This condition is a common skin issue during pregnancy, often presenting with a rash similar to rosacea. The full-body involvement could be due to the hormonal changes and immune system modulation during pregnancy.
- Other Likely diagnoses
- Pemphigoid gestationis: An autoimmune skin disorder that occurs during pregnancy, characterized by a blistering rash. Although it typically starts in the abdomen, it can spread to other parts of the body.
- Polymorphic eruption of pregnancy (PEP): A skin condition that occurs during pregnancy, often presenting with a rash on the abdomen, which can spread to other areas. The rash can be pruritic and may resemble rosacea.
- Atopic eruption of pregnancy: A condition that encompasses several skin issues, including eczema, which can present with a rash similar to rosacea and can become widespread.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Pustular psoriasis: A rare but severe form of psoriasis that can be triggered by pregnancy. It presents with widespread pustules and can be life-threatening if not treated promptly.
- Stevens-Johnson syndrome (SJS) or Toxic Epidermal Necrolysis (TEN): Although rare, these conditions are medical emergencies that can be triggered by medications or infections. They present with a severe, widespread rash and can be fatal if not recognized and treated promptly.
- Rare diagnoses
- Darier disease: A rare genetic disorder that can present with a rash similar to rosacea, but it is not typically associated with pregnancy.
- Sarcoidosis: A condition that can cause skin lesions, including a rash similar to rosacea. However, it is not typically triggered by pregnancy and is relatively rare.
