Umbolith with umbilical abscess and omphalitis: a rare case

Umbolith is a relatively rare entity under normal circumstances, especially in the urban scenario. Usually seen in obese individuals with a deep and retracted umbilicus due to constant accumulation of sebum/keratin leading to stone formation. It’s usually covert until complicated by secondary infection (abscess) or ulceration. Sinus was laid open and healthy granulation was seen within 1st week. Pus culture sensitivity suggestive of heavy staph growth and antibiotics were given accordingly. Appendicitis was treated conservatively.
