A 45-year-old male with known psoriasis presents with sudden onset of widespread, small, erythematous, droplet-like lesions. He reports recent strep throat infection. What could be the cause, and how should it be managed?
This patient's symptoms suggest guttate psoriasis, which often appears suddenly following a streptococcal throat infection. It presents as small, drop-shaped lesions usually on the trunk and limbs. Management often includes treating the streptococcal infection, if present, along with topical therapies for the skin, such as corticosteroids or vitamin D analogues. Light therapy can also be beneficial.
