A 55-year-old female with psoriasis presents with persistent scaling and crusting of her scalp. Over-the-counter dandruff shampoos have not helped. What could be the diagnosis, and how should it be managed?
This patient's symptoms are suggestive of scalp psoriasis, a common form of psoriasis that affects the scalp. Management typically involves medicated shampoos, topical corticosteroids, and vitamin D analogues. More severe cases may benefit from systemic therapies or phototherapy.
