Uncommon cutaneous manifestations of lupus erythematosus.

Cutaneous manifestations of lupus erythematosus (LE) are, usually, characteristic enough to permit an easy diagnosis. However, some patients may present less typical lesions, associated or not to the classic ones. Therefore, irrespectively of the variety of LE (acute, subacute and chronic), in absence of the typical butterfly rash, erythematosquamous papules or plaques, or any of the characteristic cutaneous alterations, it is important (even though not always easy) to recognize the uncommon and/or atypical changes of the skin.
