Patent Claims:	1. A method of treating vitiligo in an affected area of a patient comprising: topically administering to the affected skin area of the patient in need thereof a pharmaceutical composition comprising 1.5% w/w ruxolitinib, or a pharmaceutically acceptable salt thereof, on a free base basis, twice per day and the vitiligo is nonsegmental vitiligo, wherein the affected skin area comprises at least one of lower extremities, trunk, and feet of the patient, and wherein the method does not comprise administering phototherapy. 2. The method of claim 1, wherein the ruxolitinib, or the pharmaceutically acceptable salt thereof, is ruxolitinib phosphate. 3. The method of claim 1, wherein the affected skin area comprises the lower extremities of the patient. 4. The method of claim 1, wherein the affected skin area comprises the trunk of the patient. 5. The method of claim 1, wherein the affected skin area comprises the feet of the patient. 6. The method of claim 1, wherein the administering is continued until the patient achieves an increase in pigmentation in the affected skin area that is at least one of the lower extremities, the trunk, and the feet. 7. The method of claim 6, wherein the administering is for at least 52 weeks. 8. The method of claim 1, wherein the administering is continued until the patient achieves an increase in pigmentation in the affected skin area that is the lower extremities. 9. The method of claim 1, wherein the administering is continued until the patient achieves an increase in pigmentation in the affected skin area that is the trunk. 10. The method of claim 1, wherein the administering is continued until the patient achieves an increase in pigmentation in the affected skin area that is the feet. 11. The method of claim 6, wherein the patient achieves a 25% or greater improvement in Vitiligo Area Scoring Index in the affected skin area that is at least one of the lower extremities, the trunk, and the feet after 52 weeks of the administering. 12. The method of claim 6, wherein the patient: has at least 0.5% facial body surface area affected by vitiligo at baseline and at least 3% non-facial body surface area affected by vitiligo at baseline; and has been clinically diagnosed with vitiligo. 13. The method of claim 12, wherein the patient is aged 12 years or older. 14. The method of claim 1, wherein the pharmaceutical composition is an oil-in-water emulsion, which is a cream. 15. A method of treating vitiligo in an affected area of a patient comprising: topically administering to the affected skin area of the patient in need thereof a pharmaceutical composition comprising 1.5% w/w ruxolitinib, or a pharmaceutically acceptable salt thereof, on a free base basis, twice per day and the vitiligo is nonsegmental vitiligo, wherein the affected skin area comprises at least one of lower extremities, trunk, and feet of the patient, wherein the method does not comprise administering phototherapy, and wherein topically administering of the pharmaceutical composition is continued to achieve a 50% or greater improvement in Vitiligo Area Scoring Index in the affected skin area that is at least one of the lower extremities, the trunk, and the feet after 52 weeks. 16. The method of claim 15, wherein the patient: has at least 0.5% facial body surface area affected by vitiligo at baseline and at least 3% non-facial body surface area affected by vitiligo at baseline; and has been clinically diagnosed with vitiligo. 17. The method of claim 16, wherein the patient is aged 12 years or older. 18. The method of claim 15, wherein the pharmaceutical composition is an oil-in-water emulsion, which is a cream. 19. The method of claim 15, wherein the affected skin area is the lower extremities. 20. The method of claim 15, wherein the affected skin area is the trunk. 21. The method of claim 15, wherein the affected skin area is the feet.
