Cutaneous lymphoid hyperplasia
Cutaneous lymphoid hyperplasia (also known as "borrelial lymphocytoma,"[1] "Lymphadenosis benigna cutis," "Lymphocytoma cutis," "Pseudolymphoma," "Pseudolymphoma of Spiegler and Fendt,"[1] "Sarcoidosis of Spiegler and Fendt,"[1] "Spiegler–Fendt lymphoid hyperplasia,"[1] and "Spiegler–Fendt sarcoid") refers to a groups of benign cutaneous disorders characterized by collections of lymphocytes, macrophages, and dendritic cells in the skin.[2]:725 Conditions included in this groups are:[2]:725
- 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.[2]:725
- Cutaneous lymphoid hyperplasia with bandlike and perivascular patterns, a condition of the skin characterized by skin lesions that clinically resemble mycosis fungoides.[2]:726
- Jessner lymphocytic infiltrate of the skin (also known as "Benign lymphocytic infiltration of the skin,"[1] "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.[1]:1887[2]:727 It is named for Max Jessner.[3][4] It has been suggested that it is equivalent to lupus erythematosus tumidus.[5]
