Quick Review: Fungal Skin Infections

00:01 Okay, now let's do a quick review.

00:04 Again, I'll ask a question, feel free to pause the screen and unpause it when you're ready to hear the answer.

00:10 Which pairing below is correct? Alright, impetigo and cradle cap? No.

00:23 Cradle cap is what we should think of when we hear about seborrheic dermatitis in children.

00:28 Pityriasis rosea and malassezia globosa? No, Remember pityriasis rosea is actually an idiopathic condition potentially associated with a virus but not with a fungus.

00:41 Candida and 'satellite lesions'? Yes.

00:44 That's the one where you can have these beefy-red lesions and then these scattered lesions that are detached away from a confluent area, those are called satellite lesions So I think that's gonna end up being our final diagnosis here.

00:56 Tine corporis and 'greasy-looking'? Nope.

00:59 Greasy-looking should make you think about seborrheic dermatitis.

01:03 And lastly, tinea versicolor and a 'herald patch' A herald patch is one of the things that goes along with pityriasis rosea, that precedes the appearance of the 'christmas tree' So, our diagnosis is number 3.

01:19 Next question, which of the following would have a negative KOH prep? Alright, so the real question here is, which of these is not caused by a fungus? Candida is, tinea is, pityriasis versicolor-it is, onychomycosis is, vitiligo - an autoimmune condition which will not have a positive KOH prep.

01:48 Final diagnosis, number 5.

01:52 And with that, i think we're done with fungi.
