Quizplus · Accepted Answer

The description of intensely itchy "pimples" on the hands and wrists that are small inflamed streaks, but do not contain pus, is consistent with the symptoms of scabies, which is caused by the mite Sarcoptes scabiei. The mite burrows into the skin and causes an inflammatory reaction, which leads to itching and the formation of small raised streaks or bumps. Staphylococcus epidermidis is a common skin commensal and is not known to cause this type of lesion. Sporothrix schenkii is the causative agent of a fungal infection called sporotrichosis, which usually presents as nodules or ulcers on the skin. Pseudomonas aeruginosa is an opportunistic bacterial pathogen that can cause a range of infections, including skin infections, but is not commonly associated with the symptoms described. Clostridium perfringens is a bacterium that is associated with gas gangrene and other infections but is not typically associated with skin lesions.
