Next stop, we're gonna talk
about fungal skin infections.
Here's the case:
A 20-year old college lacrosse player, with no past
medical history presents with a rash on his arm.
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.
For several days, he's tried applying rubbing
alcohol to the lesion, without any improvement.
No prior similar lesions, no history of diabetes, no
recent travel, non-contributory family and social history.
He's afebrile, pretty benign
exam except for on his skin.
He has a single, raised, annular, erythematous lesion,
that's 4x5 cm in size with an irregular border,
central clearing and scale.
Alright, which of the following
is the most likely diagnosis?
Pityriasis rosea, tinea corporis, tinea
versicolor, candida intertrigo, or impetigo?
