A woman in her 40s with no significant medical history presented with a 1-year history of an umbilical nodule. She described occasional pain and intermittent bleeding from the site. Prior treatment with intralesional triamcinolone injections for a presumed keloid yielded no improvement. Physical examination showed a discrete, reddish-brown, noncompressible, smooth nodule within the umbilicus (Figure, A). There was no change in size with the Valsalva maneuver.
