A Case of Adult Filipino Male Presenting with Co-localized Psoriasis and Segmental Vitiligo

A 29-year-old male presented with a four-year history of recurrent generalized pruritic erythematous scaly annular plaques followed by a solitary depigmented patch on the right hemiabdomen extending to the back with abrupt midline demarcation. Skin biopsies confirmed the rare case of co-existing and colocalized psoriasis and segmental vitiligo. Treatment with topical steroids, tacrolimus, and narrowband ultraviolet B phototherapy resulted to the improvement of the psoriatic lesions but no change in the depigmented patch.
