An 83-year-old woman with dementia presented with an umbilical lesion that was incidentally noticed by family. She had no abdominal pain, weight loss, or night-sweats. She did not know how long it had been present. On exam she had a painless, brownish-black, dry-appearing mass (Fig. 1) protruding from her umbilicus. The mass was felt to be an Omphalolith or Umbilical Concretion. It was removed with gentle traction using forceps. It measured 3.5 × 3.0 × 1.0 cm with a brownish-black dry-appearing cap and an inferior aspect that was pearly-tan-white (Fig. 2). Histopathology showed a specimen composed of laminated keratin.
