    00:01 Next stop, we're gonna talk about fungal skin infections.

    00:06 Here's the case: A 20-year old college lacrosse player, with no past medical history presents with a rash on his arm.

    00:14 He describes an itchy, circular rash which has developed over the past 1 to 2 weeks on the lateral aspect of his right arm, shown here.

    00:22 For several days, he's tried applying rubbing alcohol to the lesion, without any improvement.

    00:27 No prior similar lesions, no history of diabetes, no recent travel, non-contributory family and social history.

    00:34 He's afebrile, pretty benign exam except for on his skin.

    00:38 He has a single, raised, annular, erythematous lesion, that's 4x5 cm in size with an irregular border, central clearing and scale.

    00:49 No pustules.

    00:51 Alright, which of the following is the most likely diagnosis? Pityriasis rosea, tinea corporis, tinea versicolor, candida intertrigo, or impetigo?
