MS-1782

A 25-year-old male visits his doctor with worries about his appearance, specifically his hair loss. He is unsure of the cause and is generally health-conscious, regularly attending the gym. Lately, he has been increasing his protein intake to aid muscle growth.

During the examination, the doctor observes a red, scaly rash around the patient’s nose and diffuse hair loss on his scalp.

What could be the potential cause of his symptoms?
