The cutaneous lesions of seven consecutive patients with cutaneous lupus erythematosus (LE), two patients with systemic LE, and a patient with both dermatomyositis and cutaneous LE, were studied bacteriologically and microscopically for the presence of bacteria. The study was prompted by the previous reports of variably acid‐fast and non‐acid‐fast bacteria in other collagen diseases, and also by recent reports confirming the presence of cell wall deficient (CWD) bacteria (staphylococci, streptococci, and corynebacteria) within the hematologic elements of both “normal” and diseased individuals. Staphylococcus epidermis was isolated from four cases, Propionibacterium acnes from two cases, and Corynebacterium sp. from one case. Three cases were bacteriologically negative. Basophilic and eosinophilic‐stained coccoid forms, suggestive of CWD bacteria, were identified in the microscopic sections of all the cases, as were non‐acid‐fast coccoid forms. Definite acid‐fast coccoid forms were observed in vivo in two cases of cutaneous LE. The complex bacteriology of LE is discussed, as well as the possibility that variably acid‐fast CWD microbes might be the long sought‐after etiologic agent or agents in the production of LE.
