Abstract

Abstract: Guttate psoriasis (GP) is a variant of psoriasis with typical drop-shaped lesions sized 0.5-1 cm in diameter, localized especially in the upper part of the body and proximal extremities. It usually occurs in young adult. We reported a female,11 years old, with red, itchy, and scaly patches distributed nearly all over the body. There was a history of sore throat. Dermatologic status showed multiple erythematous plaques which were miliar to numular, discrete, and were covered with layered silvery white scales. The Auspitz sign, wax spot phenomenon, and ASTO were positive. The histopathologic examination showed para-keratosis and Munro microabcesses. The patient treated with topical steroid for 4 weeks made improvement. Conclusion: In this case, diagnosis of guttate psoriasis was based on anamnesis, examination, and supporting examinations. Streptococcal infection was suspected as the trigger factor due to the positive ASTO examination. Topical steroid as the first line therapy for mild to moderate psoriasis made great improvement.
