REPORT OF A CASE
A 35-year-old woman and garden nursery worker presented with a 3-year history of itching, tenderness, swelling, and pain of the fingers, which were worse during the cold winter months (Figure 1). During the same period, she had developed malar photodermatitis. She had noticed acrocyanosis but no fingertip blanching in cold weather, and she had arthralgias in the distal aspect of her fingers. She also stated that there had been some thinning of the hair on her scalp over a period of several years. She denied having any other physical symptoms.Her white blood cell count was 3.6×109/L, with a normal differential cell count. The serologic tests were negative for antinuclear, anti-DNA, anti—SS-A, and anti—SS-B antibodies, and the results of the CH50 assay were normal. The findings of immunoelectrophoresis were normal except for an IgE concentration of 638 μg/L (266 IU/mL) (normal, <432 μg/L
