Cutaneous lymphoid hyperplasia (also known as "borrelial lymphocytoma," "Lymphadenosis benigna cutis," "Lymphocytoma cutis," "Pseudolymphoma," "Pseudolymphoma of Spiegler and Fendt,"〔 "Sarcoidosis of Spiegler and Fendt,"〔 "Spiegler–Fendt lymphoid hyperplasia,"〔 and "Spiegler–Fendt sarcoid") refers to a groups of benign cutaneous disorders characterized by collections of lymphocytes, macrophages, and dendritic cells in the skin. Conditions included in this groups are:〔 * ''Cutaneous lymphoid hyperplasia with nodular pattern,'' a condition of the skin characterized by a solitary or localized cluster of asymptomatic erythematous to violaceous papules or nodules.〔 * ''Cutaneous lymphoid hyperplasia with bandlike and perivascular patterns,'' a condition of the skin characterized by skin lesions that clinically resemble mycosis fungoides.〔 * ''Jessner lymphocytic infiltrate of the skin'' (also known as "Benign lymphocytic infiltration of the skin,"〔 "Jessner lymphocytic infiltration of the skin," "Jessner–Kanof lymphocytic infiltration of the skin," and "Lymphocytic infiltrate of Jessner") is a cutaneous condition characterized by a persistent papular and plaque-like skin eruption which can occur on the neck, face and back and may re-occur. This is an uncommon skin disease and is a benign collection of lymph cells. The cause of this is not known and can be hereditary.〔〔 It is named for Max Jessner. It has been suggested that it is equivalent to lupus erythematosus tumidus. == See also == * Skin lesion * List of cutaneous conditions * Tick bite * Lyme disease 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「Cutaneous lymphoid hyperplasia」の詳細全文を読む スポンサード リンク
