1.  ‘Lint ball’ omphalitis, a rare cause of umbilical discharge in an adult woman: a case report 
Cases Journal  2009;2:7785.
Umbilical discharge in adult is rare and is usually induced by foreign material, most commonly hair. Rarely, it may be due to embryonal anomalies. We are reporting an unusual case of umbilical discharge in adult secondary to an impacted lint ball.
Case presentation
A 55-year-old obese woman presented with a 4-month history of hemorrhagic discharge from the umbilicus. Deep from the base of the umbilicus, a 0.8 cm gray-tan mass was removed that on microscopic examination revealed a lint ball.
An impacted lint ball may be a rare cause of umbilical discharge in adult.
