This slide shows a facial eruption in a patient with systemic lupus erythematosus. The rash consists primarily of erythema on the malar and chin areas. Telangiectasias are also present. This type of lesion is suggestive but not diagnostic of systemic lupus.

Diffuse alopecia is seen in the scalp of this patient with systemic lupus erythematosus. Diffuse hair loss is most common in systemic lupus, although patchy baldness can appear. The hair usually regrows slowly when the disease becomes inactive. Not seen in this slide are the short hairs with a cut-off appearance, found in the frontal scalp area, that are typical of alopecia. Localized lesions of discoid lupus may damage hair follicles and result in permanent alopecia.

Necrotic lesions due to vasculitis are seen on the fingertips of this patient with systemic lupus erythematosus. These skin changes appeared after a rather abrupt onset of pain in the fingers, probably resulting from an occlusion of small distal arteries. Vasculitis can also produce palpable purpura, small ulcerations, and subsequent superficial depressed scars over the fingertips.

The marked pallor of the fourth and fifth digits on the left hand and of the fifth
digit on the right hand is characteristic of Raynaud's phenomenon. Vasospastic changes are common in systemic sclerosis but may also occur in rheumatoid arthritis, systemic lupus erythematosus, and idiopathic Raynaud's disease.

The cyanotic phase of Raynaud's phenomenon is seen in the fingers of this patient with scleroderma. Telangiectasias and palmar erythema are also present.
