Lymphocytic thrombophilic arteritis induced by minocycline

Lymphocytic thrombophilic arteritis is an entity only recently defined in the literature. This term describes a distinctive histopathological combination of lymphocytic vascular inflammation associated with a hyalinized fibrin ring in the vessel lumina, changes reflecting a thrombophilic endovasculitis. The authors present the case of a woman who developed lymphocytic thrombophilic arteritis coinciding with the use of minocycline. In addition to these histopathological findings, the cutaneous manifestations of this case reflect previously reported clinical findings of progressive localized livedo racemosa characterized by reticular patchy hyperpigmentation predominately affecting the lower extremities.
