The many faces and phases of borreliosis II.

Borrelia burgdorferi, the etiologic agent of Lyme disease, has also been associated with other cutaneous conditions. Acrodermatitis chronica atrophicans and lymphadenosis benigna cutis are also caused by B. burgdorferi. Recent evidence links some cases of progressive facial hemiatrophy of Parry-Romberg, benign lymphocytic infiltrate of the skin (Jessner-Kanof), lichen sclerosus et atrophicus, morphea, and Shulman syndrome with borreliae. This article reviews the manifestations of the diseases definitely linked to borreliosis and the evidence linking borreliae to progressive facial hemiatrophy, benign lymphocytic infiltrate, lichen sclerosus et atrophicus, morphea, and Shulman syndrome.
