A 28-year-old man presents with a 6-week history of the rash pictured above on his chest and back. He has a history of hand dermatitis that he thinks is related to washing his hands often in his work as a surgery resident. He has no other skin-related issues. He thinks that he had a similar rash on the chest and back last summer, which improved without treatment during the winter. The rash is not itchy, but the appearance bothers him. On exam, the lesions have fine, diffuse scale, and Wood’s lamp examination shows fluorescence.

What is the diagnosis?
A. Syphilis
B. Tinea versicolor
C. Pityriasis rosea
D. Psoriasis
E. Tinea corporis
