Panniculitis: a cutaneous manifestation of dermatomyositis.

Specific and nonspecific panniculitis sometimes occurs during the course of connective tissue diseases. However, the association of panniculitis and dermatomyositis (DM) has only rarely been described. Previous reports have suggested that panniculitis may be an inherent part of DM but, because the cases reported are few, it is difficult to know the significance of this unusual association. We describe 2 patients with DM in whom panniculitis developed during the course of the disease, and discuss its clinical and diagnostic significance.
