RESUMEN
The clinical feature of secondary syphilis is of `the great imitator'. The rarity of clinical syphilis today has led to an erosion of clinical skills to determine this condition. It is important for physicians to keep in mind that any atypical skin lesions may be syphilid. We report two cases of psoriasiform syphilid in a 64-year-old man and a 45-year-old woman. They presented with multiple, erythematous to brown colored scaly papules and plaques on the abdomen, back and chest. The differential diagnosis included papulosquamous diseases, especially psoriasis. Histopathologic findings were not consistent with that of psoriasis, but consisted rather with that of interface dermatitis. Serum VDRLs were strongly positive (1: 256 and 1: 64, respectively), and TPHAs were positive, too. After intramuscular treatment with 2.4 million units of benzathine penicillin G, the skin lesions cleared within 1 month.

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.
