The histologic profile of discoid lupus erythematosus typically involves a vacuolar interface reaction with an associated superficial and deep perivascular infiltrate composed of lymphoplasmacytes. We present a unique case of discoid lupus erythematosus in which cluster of differentiation 68 (CD68) immunochemistry identified widely dispersed histiocytes. The gene discussed is CD68; the disease is discoid lupus erythematosus.
