Differential Diagnosis for Sandpaper Rash
- Single most likely diagnosis
- Scarlet fever: This is the most likely diagnosis for a sandpaper rash, as it is a classic symptom of the disease. Scarlet fever is caused by group A beta-hemolytic streptococci and is characterized by a bright red, sandpapery rash that covers most of the body.
- Other Likely diagnoses
- Kawasaki disease: This disease is an acute febrile illness that can cause a rash, including a sandpapery rash, and is often seen in children. It is an important diagnosis to consider, as it can lead to cardiac complications if left untreated.
- Toxic shock syndrome: This is a life-threatening condition caused by bacterial toxins, often associated with a sandpapery rash, fever, and hypotension.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Staphylococcal scalded skin syndrome (SSSS): This is a rare but serious condition caused by staphylococcal toxins that can cause a sandpapery rash, as well as widespread skin exfoliation and potentially life-threatening complications.
- Streptococcal toxic shock syndrome: This is a severe and potentially life-threatening condition caused by streptococcal toxins, which can cause a sandpapery rash, fever, and hypotension.
- Rare diagnoses
- Erythema infectiosum: This is a viral infection that can cause a sandpapery rash, but it is relatively rare and usually mild.
- Drug reactions: Certain medications can cause a sandpapery rash, but this is relatively rare and would require a thorough medication history to diagnose.
