Omphalolith (umbolith) is an uncommon entity under normal circumstances. However, in a deeply retracted umbilicus in an obese individual, the 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 interesting case of an omphalolith in a young woman.  In our literature search, very few cases of omphalolith have been reported.
