Omphalolith (Umbolith) is uncommon under normal circumstances. However in a deeply retracted umbilicus in an obese individual, accumulation of sebum and keratin may lead to the formation of a stone. This calculus may remain undiagnosed for many years until revealed by secondary infection or ulceration.We report an intersting case of omphalolith in an elderly woman.
