Abstract

Omphalith is a compaction of keratinous and sebaceous material in the deeply set umbilicus. It may be clinically mistaken for a malignant melanoma because of its pigmented surface and sudden appearance. However, careful probing and removal of this umbilical mass, followed by histopathological examination readily identifies its true nature. We describe a patient who presented with a firm, black umbilical mass diagnosed as an omphalith and reviewed the differential diagnosis of a firm, black umbilical mass.
