Clinical Presentation

52-year-old woman.

This woman complained of a nodule on her finger (Figure) that had been present for 5 weeks. She requested removal. After lidocaine anesthesia, the top of the papule was removed via shave technique, and the viscous material was forced out of the base of the nodule. The specimen was submitted to the pathology laboratory to confirm the diagnosis. No cautery, cryotherapy, or other destructive procedures were performed. The nodule returned at the same location 3 weeks later. The various treatment options were reviewed, and the patient opted for surgical excision.
