a prodrome of fever (over 38.3 C, or 101 F), cough, coryza, and conjunctivitis, this maculopapular rash starts on the neck, behind the ears, and along the hairline. It spreads downward, reaching the feet in two or three days. The initial rash appears on the buccal mucosa as red lesions with bluish white spots in the center
measles (kopilk spots)
is macular or maculopapular rash, also called exanthem subitum, starts on the trunk and spreads to the arms and neck. There is usually less involvement of the face and legs. The rash is preceded by three or four days of high fevers, which end as the rash appears. It is usually seen in children less than two years old.

An acute hypersensitivity syndrome
Associated with a symmetrical rash that starts as a dusky red macules and evolves into sharply demarcated wheals and then into target-like lesions.
erythema multiforme
assc ewith HSV and drug rxn
Keratinous material and excess sebum (due to androgenic influence) plug the pilosebaceous glan
acne vulgarus
Pustular lesions caused by occlusion of the apocrine follicular units (instead of the pilosebaceous units).
Often superinfected with Staphylococcus aureus or Streptococcus pyogenes.

hidradenitis suppurative
Worsens with alcohol, spicy food, temperature extremes, and stress. + treatment

nickel allergy is what type of HS rxn

topical griseofulvin
coin-shaped lesions commonly on the legs and buttocks. It has an annular configuration and scaly appearance like tinea.
Nummular eczema
nonspecific dermatitis characterized by patches of hypopigmentation on the face, neck, upper trunk, and proximal extremities. Lesions range from 0.5 to 5 cm in diameter with well-defined, irregular borders and fine scale. It is associated with sun exposure. It can be mistaken for tinea versicolor.
Pityriasis alba
characterized by scaly papules and plaques in the hallmark “christmas tree” distribution on the back and trunk, following the lines of skin cleavage. Lesions may also be found on the upper thighs and in the groin area. The initial lesion, called the “herald patch,” is usually the largest scaly plaque with a raised border and can easily be confused with tinea corporis.
