Vitamin K1-induced localized scleroderma (morphea) with linear deposition of IgA in the basement membrane zone. 1998

Department of Dermatology, Mayo Clinic and Mayo Foundation, Rochester, Minnesota, USA.

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.

D010837	Vitamin K 1	A family of phylloquinones that contains a ring of 2-methyl-1,4-naphthoquinone and an isoprenoid side chain. Members of this group of vitamin K 1 have only one double bond on the proximal isoprene unit. Rich sources of vitamin K 1 include green plants, algae, and photosynthetic bacteria. Vitamin K1 has antihemorrhagic and prothrombogenic activity.	Phylloquinone,Phytomenadione,Phytonadione,Aquamephyton,Konakion,Phyllohydroquinone,Vitamin K1

D000933	Antifibrinolytic Agents	Agents that prevent fibrinolysis or lysis of a blood clot or thrombus. Several endogenous antiplasmins are known. The drugs are used to control massive hemorrhage and in other coagulation disorders.

D001485	Basement Membrane	A darkly stained mat-like EXTRACELLULAR MATRIX (ECM) that separates cell layers, such as EPITHELIUM from ENDOTHELIUM or a layer of CONNECTIVE TISSUE. The ECM layer that supports an overlying EPITHELIUM or ENDOTHELIUM is called basal lamina. Basement membrane (BM) can be formed by the fusion of either two adjacent basal laminae or a basal lamina with an adjacent reticular lamina of connective tissue. BM, composed mainly of TYPE IV COLLAGEN; glycoprotein LAMININ; and PROTEOGLYCAN, provides barriers as well as channels between interacting cell layers.

D012594	Scleroderma, Localized	A term used to describe a variety of localized asymmetrical SKIN thickening that is similar to those of SYSTEMIC SCLERODERMA but without the disease features in the multiple internal organs and BLOOD VESSELS. Lesions may be characterized as patches or plaques (morphea), bands (linear), or nodules.
