Abstract
A 17-year-old woman presented with pruritic papules and plaque wheals on the upper and lower extremities, back, chest, and abdomen, which had appeared 4 months previously. Previous medical history revealed two surgical operations for ovarian cysts (the latter was 2 weeks prior to admittance to the hospital). There was family (brother) but no personal history of atopy, with no known drug allergies. A prior biopsy demonstrated urticaria. Physical examination revealed symmetric, widespread, pink-red plaques with central clearing mostly on the buttocks, but also on the upper and lower extremities and trunk. With pressure, the lesions almost disappeared. Lymph nodes could not be palpated, and all other systems were normal (1-3).

Urinalysis and urine cultures were normal. There were no parasites in the feces. Sinus and chest X-ray were normal, as was an ear, nose and throat (ENT) examination. An elevated sedimentation rate (23/58) was obtained. A second biopsy revealed features compatible with Wells' syndrome (Fig. 4).
