Abstract Two siblings with generalized pustular psoriasis were admitted to the hospital. Case 1: A 7-year-old girl presented with recurrent episodes of multiple pinhead-sized pustules all over her body since the age of 3. The current episode began a week prior to the onset of the lesions. On cutaneous examination, she had generalized erythema topped with tiny pustules, scales, and crusting (Figure 1A). A Gram stain performed from the pustule and cultures taken from the pus and blood were sterile. Histopathology of the pustule was suggestive of pustular psoriasis (Figure 2). Hemoglobin was 8.8 g\%. Other hematologic, microbiologic, and radiologic investigations were normal. Treatment was started with methotrexate, to which she responded dramatically with reduction in appearance of new lesions, erythema, and scaling. After 4 weeks of treatment, there was almost 90\% clearance of skin lesions. Case 2: A 3-year-old boy, brother of the patient in case 1, presented with similar complaints for the past week. The episode was preceded by high-grade fever. He had generalized erythema, scaling, and edema and multiple pinhead-sized pustules, some of which were arranged in an annular configuration (Figure 1B). All investigations, as in case 1, were normal except for hypocalcemia (Ca2+ = 8.8 g\%) and generalized rarefaction on x-rays of both the ankle joints. Treatment was started with prednisolone (because of poor general condition) and methotrexate. Following therapy, significant improvement was evident with reduction in erythema and cessation of appearance of new pustules. The dose of prednisolone was gradually tapered after 3 weeks and then stopped.
