Abstract

Psoriasis is a chronic immune-mediated inflammatory disease characterized by epidermal hyperproliferation, abnormal keratinocyte differentiation, and systemic inflammation. Psoriasis may present in several clinical forms, including plaque psoriasis and pustular psoriasis. This case report describes a 27-year-old woman who presented with multiple painful purulent lesions on both thighs, the abdomen, and the chest for one week, accompanied by fever, headache, and nausea. Dermatological examination revealed multiple purulent lesions with an erythematous base on both femoral regions, with desquamation on ruptured lesions. Multiple well-demarcated erythematous plaques with silvery-white scales were also observed on the trunk and dorsal region. Laboratory examination showed mild leukocytosis (WBC 12.44 × 103/µL) and a random blood glucose of 284 mg/dL. The Psoriasis Area and Severity Index (PASI) score was 15.6, indicating moderate disease severity. The working diagnosis was localized pustular psoriasis associated with plaque psoriasis, with bullous pemphigoid and pityriasis lichenoides considered in the differential diagnosis. The patient received supportive and symptomatic treatment consisting of intravenous Ringer’s lactate, paracetamol, omeprazole, dexamethasone, cetirizine, and carbamide cream. This case illustrates the importance of recognizing pustular lesions accompanied by systemic symptoms in patients with psoriasis and of objectively assessing disease severity using a validated scoring instrument. Appropriate management and monitoring are required, as pustular psoriasis may involve systemic complications and a recurrent disease course.
