title: A case of secondary syphilis with a solitary pulmonary lesion.
abstract: This study describes a case of secondary syphilis with a papular eruption and penile ulceration. A chest roentgenogram showed a solitary lesion in the left middle lung field. Histological examination revealed epithelioid cell granuloma in both the penile ulcer and the lung lesion. After antisyphilitic treatment, the lung lesion shrunk remarkably and at the same time the skin eruption and the systemic symptoms also improved.
