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.
