They are usually seen on the palms and soles. S. circinatum, circulate, orbicular, or annular syphilid; lepra syphilitic a; a form of squamous syphilitic skin-eruption of the secondary period.

It occurs in circles from half an inch to an inch in diameter, which may form gyrate figures with clear centers and sharply defined, distinctly raised borders, with some scales.
