Scabies is caused by the Sarcoptes scabiei mite, which burrows into the skin and leads to intense itching, especially in areas such as the web spaces between fingers, wrists, and the soles of the feet. It often manifests as a rash characterized by papules, vesicles, and sometimes excoriation due to scratching. The specific distribution of the rash in these areas is particularly indicative of scabies, as it commonly affects thin-skinned regions of the body where mites can easily burrow.

While contact dermatitis can occur in any location where the skin has been exposed to an irritant or allergen, it is less likely to specifically present in the web spaces of fingers and on feet as a primary pattern. Erythema multiforme typically presents with target-like lesions and is often associated with infections or drugs, rather than a presentation limited to finger and foot areas.
