A Case of Colocalized Vitiligo and Psoriasis.

BACKGROUND

Psoriasis and vitiligo are common dermatologic conditions with underlying autoimmune etiologies. There are few reports of concomitant and colocalized disease. Several theories have been proposed to explain this rare presentation.

OBJECTIVE

The objective of this study was to present a rare case of a concomitant and colocalized presentation of vitiligo and psoriasis.

METHODS

Case report.

RESULTS

A 72-year-old male was referred for treatment of a 30-year history of psoriasis and 5-year history of colocalized vitiligo. The patient had no other underlying autoimmune diseases including psoriatic arthritis.

CONCLUSION

Clinicians should be aware of the possible concomitance and colocalization of psoriasis and vitiligo. Further research is needed to elucidate the common pathways leading to the concomitance and colocalization of these diseases.
