Flea bites (helps you remember the appearance)

Is it possible to miss the vesicle phase of transient neonatal pustular melanosis, even if you have been examining the child from birth?

Yes – sometimes the disorder starts in utero(!) so the vesicle phase is already over when the baby is born

How often does aplasia cutis congenita occur as a single lesion?

70 %

Aplasia cutis congenita can occur anywhere on the body. Where are the lesions most often found?

80 % are scalp lesions – usually at the vertex (highest point on the scalp)

If you identify a lesion of aplasia cutis congenita, how should you treat it?

Usually heals on its own

If a lesion of aplasia cutis congenita has already healed on its own, how might you still notice on physical exam that the lesion was previously there?

No hair in a spot on the scalp – The lesion is deep enough that, even when it heals, there are no skin appendages present (glands, hair follicles, and hair)

If you see lesions on the extremities that look like cigarette burns, what infectious agent could be the culprit?

Oral cephalexin

Do you need to worry about your patient developing rheumatic fever (or PANDAS – the neuropsych complications of strep infection), if he or she has developed impetigo?

No – skin infections don’t do that

(throat infections do)

(but post-strep glomerulonephritis is still possible)

Which medication causes allergic contact dermatitis most often?

Neomycin

(topical ointment)

If a patient has been exposed to poison ivy, or something similar (an urushiol), can the dermatitis be spread by the fluid from the bers?

No

Can the contact dermatitis of poison ivy be spread by itching the area, then touching another area?

Sometimes – if the exposure was recent, the fat-soluble urushiol will still be in or on the skin – itching can lodge some under the nails and allow spread to another site
