Statistics from Altmetric.com

A 33 year old woman attended the rheumatology clinic for assessment of her cutaneous lupus. The diagnosis of cutaneous lupus had been made by her dermatologist five years beforehand; this was confirmed by biopsy. She subsequently developed a positive anti-DNA antibody at low titres, with negative extractable nuclear antigen, but had no other clinical symptoms of systemic lupus.

The figure shows one of several active cutaneous lupus lesions overlying a butterfly tattoo, which had predated any of her symptoms.
