A Case of Psoriasiform Syphilid / 대한피부과학회지

ABSTRACT

Psoriasiform lesion is rare in secondary syphilis. We report a case of psoriasiform syphilid in a 36-year-old man, who showed condyloma lata on the perianal area and multiple erythematous scaly plaques on the face, glans penis, scrotum, and both palms and soles. He had sexual contact with prostitute about 3 months ago. The differential diagnosis included papulosquamous diseases, especially psoriasis but a psoriasiform syphilid was confirmed through skin biopsies and serologic tests. The patient was treated with benzathine penicillin G 2.4 million units intramuscularly weekly for 3 weeks. After the treatment with benzathine penicillin G, the skin lesions disappeared completely.
