Differential Diagnosis & Pitfalls
- Miliaria rubra is often mistaken for a drug eruption, especially after a new antibiotic is started in a febrile patient.
- Other miliaria variants – Miliaria crystallina, miliaria pustulosa, miliaria profunda.
- Candidiasis – Often has some pustules.
- Scabies – Unlike miliaria, often involves acral sites; check for the presence of burrows in the finger webs.
- Varicella – Presents as vesicles on an erythematous base ("dewdrops on a rose petal"), and lesions are in different stages of development.
- Folliculitis – Has follicular-based pustules.
- Acne – Can also be worsened by occlusion but usually lacks pruritus and is less acute.
- Acute generalized exanthematous pustulosis (AGEP) – Is more diffuse with widespread pustules.
- Grover disease – Also flares on the back of hospitalized patients with resulting very pruritic papules and erosions.
