Omphalolith: An underdiagnosed entity

Wafa Jouini et al. Clin Case Rep. .

Abstract

Omphalolith is a rare and underdiagnosed entity due to the accumulation of sebum and keratin in the umbilicus. It usually occurs in the elderly with deep and narrow umbilicus. Early recognition of omphalolith is important to prevent complications, unnecessary investigations, and anxiety. We report herein two new cases of omphalolith.

Keywords: Mary Joseph's nodule; Omphalolith; Wilson's disease; endometriosis; metastasis; umbilicus.
