CME Credits: 1.00
Released: 2023-12-04
A 52-year-old presented to the rheumatology clinic with 3 weeks of pain and duskiness of the fingertips bilaterally. The patient reported no dyspnea, cough, nasal discharge, diarrhea weight loss, or fevers. She had no history of rheumatologic disease or Raynaud disease, did not smoke cigarettes, take daily medications, ingest raw meat, or report recent travel. On presentation, her temperature was 98.2 °F (36.8 °C); blood pressure, 132/70 mm Hg; heart rate, 86/min; and oxygen saturation, 99% on room air. Findings on the physical examination were normal, other than her fingertips, which were cold and cyanotic with small ulcerations on the second and third fingertips (). White blood cell count was 25.1?×-109/L (reference range, 3.8-9.8?×-109/L) and manual differential revealed 74.5% eosinophils (absolute eosinophil count, 18.7?×-109/L) and no blasts. Hemoglobin level and platelet count were normal. D-dimer level was 1.5 ?g/mL (8.21 nmol/L) (reference range, 0.0-0.99 ?g/mL [0.0-5.42 nmol/L]). Test results were negative for antinuclear antibodies, antiphospholipid antibodies, antineutrophil cytoplasmic antibodies against proteinase 3 and myeloperoxidase, and HIV. Results of computed tomography of the neck, chest, abdomen, and pelvis, and of flexible nasopharyngoscopy, were normal.
