Thats a first for me…The guy went to the Doctor because he a huge black “stone” in his belly button!

YT Commentary:

“This young man attended our OPD for health check up.On examination of his abdomen I found some interesting Unusual thing in his naval belly.First I felt as if patient has done naval piercing. But on close inspection , deep in his umbilicus I found it not a navel piercing,but some black mass popping his head out side.It was deeply buried inside the naval belly , black in color and difficult to remove.
Patient gives history of presence of this hard mass in his bally button for many years.He felt pain whenever he tried to remove it from his naval opening.
It is called Black stone or calculus of umbilicus .
Also called Umbolith or Omphalolith.
It is usually present as black mass in umbilicus but in small size.But in this case it was of 1 cm x 0.7 cm size black hard stone in his naval belly (umbilicus) which is quite rare.People those do not have good personal hygiene, who never clean properly their belly button , can develop these type of stones.
Chemically it is mainly composed of Keratin and sebum.It is called stone as it is hard in nature.
Patient may remain asymptomatic or may present as pain,swelling and discharge from umbilicus.”
