[Histoplasmin skin test and focal hemorrhagic chorioiditis (author's transl)]

A histoplasmin skin test was performed on 56 patients with focal hemorrhagic choroiditis. The test was negative in 53 choroiditis patients and positive in three patients. The three patients with posi-ive skin test had been living for a long time in the eastern part of the U.S.A. where histoplasma capsulatum occurs endemically. The results of this study suggest that the infection with histoplasmin capsulatum is not the cause of focal hemorrhagic choroiditis in our area.
