The patient presented with metabolic dysregulation, severe psoriatic lesions, and hepatic steatosis. Initial therapies, including acitretin and topical agents, failed to yield clinical improvement. Semaglutide was initiated at 0.25 mg/week, titrated to 1 mg/week over 12 weeks, alongside metformin dose adjustment. At 24 weeks, the patient exhibited significant improvements: HbA1c decreased from 9.8 to 7.2%, body weight reduced by 6 kg, liver enzymes returned to normal ranges, and PASI declined to 6.2. Treatment was well-tolerated with no severe adverse events.
