Skin biopsy indicates subacute lupus erythematosus: (A) sporadic lymphocytes seen in the lower epidermis with some pigment incontinence indicating subtle interface dermatitis, (B) alcian blue-PAS (periodic acid-Schiff) stain highlights increased dermal mucin, mainly superficially, (C) IgM direct immunofluorescence highlights an apoptotic keratinocyte in the papillary dermis center field, (D) C3 focal granular staining at the dermo-epidermal junction upper center field.

Skin biopsy via direct immunofluorescence revealed some granular staining for IgG, C3, and fibrin as well as cytoid bodies staining with paucicellular vacuolar/lichenoid interface dermatitis that were strongly suggestive of subacute lupus erythematosus (Figure 1).
