[A special form of lupus disease. Deep cutaneous lupus. Apropos of 2 cases]

Deep cutaneous lupus is a clinical form of lupus disease for which a very old description has recently been brought up to date. Two new cases are reported here and a review of the literature makes it possible to analyse the clinical, biochemical, histological, and immunological features of this panniculitis. Different from the Weber-Christian syndrome, it is characterized by repeated eruptions of nodules and/or subcutaneous plaques, and histologically by vasculitis, lymphocyte infiltration, and sometimes te presence of immunoglobulins on the basal dermal membrane and around the vessels.
