Objective This study aimed to describe 2 cases of vulvar psoriasis and vitiligo resulting in a striking clinical appearance.

Materials and Methods Case 1 was of a 41-year-old woman concerned about a dark pigmentation around the introitus. Case 2 was of an 80-year-old woman with vulvar itch and red, white, and brown areas.

Results The vulva in each case showed a tricolored appearance of well-demarcated red, white, and brown colors. Biopsies showed psoriasis superimposed on vitiligo in the red, vitiligo in the white, and normal skin in the brown areas.

Conclusions When psoriasis and vitiligo are colocalized, the redness of the psoriasis may mask the vitiligo resulting in a striking red, white, and brown tricolored appearance.

The combination of vulvar psoriasis and vitiligo manifests a striking tricolored appearance.
