A 60-year-old female with a history of psoriasis presents with painful skin ulcers on her lower legs. Physical examination shows well-defined ulcers with a purple-red border. What could be the diagnosis, and how should it be managed?
This patient's presentation suggests pyoderma gangrenosum, a rare skin condition associated with systemic diseases like psoriasis. Pyoderma gangrenosum usually presents as painful ulcers with purplish borders, most commonly on the lower legs. Treatment typically involves systemic corticosteroids or other immunosuppressive drugs. Topical treatments and wound care can also be part of the management. She should be referred to a dermatologist for further evaluation and management.
