A

40
Q

A result of a mite infection. The female mites burrow into the epidermis, laying eggs over a period of several weeks. The larvae hatch from the eggs and then migrate to the skin’s surface. The larvae burrow into the skin in search of nutrients and mature to repeat the cycle. The burrowing and fecal matter left by the mites trigger the inflammatory process, leading to erythema and pruritus

A

Scabies

41
Q

A lice infestation that can take three forms - Pediculus humanus corpus (body louse), Pediculus pubic (public louse), and Pediculus humanus capitis (head louse). Lice are small, brown, parasitic insects that feed off human blood and cannot survive for long without the human host

Acne vulgaris

44
Q

A chronic inflammatory skin condition that typically affects the face. It is poorly understood, but it is prevalent in persons who are fair skinned, persons who bruise easily, and women. It may present as erythema, prominent spiderlike blood vessels (telangiectasia), swelling, and acnelike eruptions
