Lupus erythematosus profundus with unusual skin manifestation: subcutaneous nodules coexisting with eyelid plaques.

A 71-year-old Japanese woman presented with erythematous plaques on the eyelids and subcutaneous indurations or nodules with or without overlying erythema on the hands, thigh, and leg. She also had oral ulcers, arthralgia and a low grade fever. Laboratory tests revealed an elevated titer of antinuclear antibody, an increased erythrocyte sedimentation rate and anemia. Skin biopsy specimens from the hand and thigh showed lymphocytic perivascular and periappendageal infiltrates and vacuolar alterations at the basement membrane zone of the skin appendages. Moreover, there was a dense lymphocytic infiltrate deep in the dermis with extension into the subcutaneous fat, which was compatible with the diagnosis of lupus erythematosus profundus. Although the biopsy specimen from the eyelid lesion did not contain the subcutaneous fat, the changes in the dermis were essentially the same as those of the hand and thigh. The eruption as well as the other symptoms promptly responded to oral prednisolone.
