Lupus panniculitis, also termed lupus profundus, consists of erythematous or flesh-colored subcutaneous nodules. The lesions occur on the face, upper outer arms, shoulders, and trunk, including the breasts. They sometimes show overlying follicular plugging, epidermal atrophy, and hyperpigmentation—changes associated with cutaneous (discoid) lupus erythematosus (Fig. 19-4). The overlying skin can be “bound down” to the subcutaneous nodule or plaque, resulting in an obvious depression in the skin surface.
