Zoon's balanitis

Abstract

Zoon's balanitis, is typically found in older, uncircumcised males and can be asymptomatic, pruritic, or cause dysuria. The typical appearance is erythematous, discrete, moist plaques with a "cayenne pepper" speckled appearance and an orange hue on the glans penis and sometimes prepuce, which may display "kissing lesions" on areas that are in direct contact with the lesions.These may eventually erode and leave a "rusty stain". Histologically, these have a dense lichenoid infiltrate in the upper and mid dermis with abundant plasma cells.
