A 35-year-old man with a history of moderate-to-severe plaque psoriasis presented to the dermatology clinic with new skin lesions. His psoriasis had been in remission for the past 18 months while on risankizumab. Two weeks before presentation, the patient had undergone his first ever session of wet cupping therapy to treat low back pain. During the treatment, clusters of small incisions had been made at different sites across his back, after which glass cups had been applied with negative pressure to draw out small amounts of blood. What is the most likely diagnosis?
