Iridocyclitis and an iris mass associated with secondary syphilis.

A 34-year-old white man developed iridocyclitis and an iris mass. The iridocyclitis was preceded by a nodular rash which spared the palms and soles. An anterior segment fluorescein angiogram was performed which showed numerous permeable vessels. An ultrasound examination of the mass showed that it extended to the ciliary body. He had both a positive RPRCT and FTA-Abs. A skin biopsy was done which disclosed the nodules to be a rare form of secondary syphilis. The patient was treated with topical steroids and a cycloplegic agent, and later prednisone and intravenous penicillin, with eventual resolution of iris mass, iridocyclitis and skin nodules.
