Vitamin K1–induced localized scleroderma (morphea) with linear deposition of IgA in the basement membrane zone - 09/09/11
Abstract |
We describe a 45-year-old white man in whom distinctive clinical and histologic features of localized scleroderma developed at sites of injection of vitamin K1 (phytonadione). A direct immunofluorescence test demonstrated prominent linear deposition of IgA along the basement membrane zone. No circulating antibasement membrane zone IgA antibodies were identified on indirect immunofluorescence testing. We believe that the unusual immunofluorescence finding in our patient is nonspecific and represents an epiphenomenon caused by cutaneous injury. (J Am Acad Dermatol 1998;38:322-4.)
