Narrowband ultraviolet B phototherapy for inflammatory vitiligo with raised borders associated with Sjögren’s syndrome

Abstract

Conflict of interest: none declared. Inflammatory vitiligo with raised borders (IVRB) is considered to be a type of vitiligo vulgaris. Although narrowband ultraviolet B (NB‐UVB) phototherapy is one of the most effective therapies for vitiligo vulgaris, no reports on the effectiveness of NB‐UVB for IVRB had yet been described.1 We present a case of IVRB associated with Sjögren’s syndrome (SS), which showed good response to NB‐UVB therapy. A 53‐year‐old Japanese woman was referred to our vitiligo clinic for evaluation of itchy depigmented areas on the back. She had a 5‐year history of SS with antinuclear antibody (1 : 320) and was positive for anti‐SSA and SSB antibodies. On physical examination, a few lesions of vitiligo (approximately 100 mm in diameter), circumscribed with raised scaly erythema, were found on the back (Fig. 1a). On the neck, small lesions of vitiligo without erythema were also found. Results of repeated potassium hydroxide examinations were negative.
