Morphea, also known as "localized scleroderma", or "circumscribed scleroderma", involves isolated patches of hardened skin with no internal organ involvement. ==Classification== * Morphea–lichen sclerosus et atrophicus overlap is characterized by both lesions of morphea and lichen sclerosus et atrophicus, most commonly seen in women.〔 * Generalized morphea is characterized by widespread indurated plaques and pigmentary changes, sometimes associated with muscle atrophy, but without visceral involvement.〔 * Morphea profunda involves deep subcutaneous tissue, including fascia, and there is a clinical overlap with eosinophilic fasciitis, eosinophilia-myalgia syndrome, and the Spanish toxic oil syndrome.〔 Morphea profunda shows little response to corticosteroids and tends to run a more chronic debilitating course.〔 * Pansclerotic morphea is manifested by sclerosis of the dermis, panniculus, fascia, muscle, and at times, the bone, all causing disabling limitation of motion of joints.〔 * Linear scleroderma is a type of localised scleroderma which is an autoimmune disease characterized by a line of thickened skin which can affect the bones and muscles underneath it. It most often occurs in the arms, legs, or forehead, and may occur in more than one area. It is also most likely to be on just one side of the body. Linear scleroderma generally first appears in young children.〔James, William; Berger, Timothy; Elston, Dirk (2005). ''Andrews' Diseases of the Skin: Clinical Dermatology''. (10th ed.). Saunders. Page 171. ISBN 0-7216-2921-0.〕 * Frontal linear scleroderma (also known as en coup de sabre or morphea en coup de sabre) is a type of linear scleroderma characterized by a linear band of atrophy and a furrow in the skin that occurs in the frontal or frontoparietal scalp. Multiple lesions of ''en coup de sabre'' may coexist in a single patient, with one report suggesting that the lesions followed Blaschko's lines.〔 It gets its name from the perceived similarity to a sabre wound. * Atrophoderma of Pasini and Pierini (also known as "Dyschromic and atrophic variation of scleroderma,"〔 "Morphea plana atrophica,"〔 "Sclérodermie atrophique d'emblée"〔) is a disease characterized by large lesions with a sharp peripheral border dropping into a depression with no outpouching, which, on biopsy, elastin is normal, while collagen may be thickened.〔Freedberg, et al. (2003). ''Fitzpatrick's Dermatology in General Medicine''. (6th ed.). Page 1029. McGraw-Hill. ISBN 0-07-138076-0.〕 Atrophoderma of Pasini and Pierini affects less than 200,000 Americans and is classified as a rare disease by http://rarediseases.info.nih.gov...") The disease results in round or oval patches of hyper-pigmented skin. The darkened skin patches may sometimes have a bluish or purplish hue when they first appear and are often smooth to the touch and hairless. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「morphea」の詳細全文を読む スポンサード リンク
