Sebaceous cysts are also a cause of belly button discharge in some cases. The sebaceous glands release oil in the skin. If one of these glands in or near the belly button gets backed up or clogged with dirt and oil, a cyst may form under the skin.
It is characterized by abdominal pain, and fever if infected. It may rupture, leading to peritonitis, or it may drain through the umbilicus. Urachal cysts are usually silent clinically until infection, calculi or adenocarcinoma develop.
Urachal remnant infections can be considered in adults with umbilical purulent drainage. Early diagnosis and treatment may prevent subsequent complications such as infection, including sepsis as well as the potential long-term complication of adenocarcinoma.
Before birth, there is a canal between the belly button and the bladder called the urachus. In most cases this canal goes away before birth. But sometimes part of the urachus remains after birth.
The urachus is a fibrous remnant of the allantois, a canal that drains the urinary bladder of the fetus that joins and runs within the umbilical cord. The fibrous remnant lies in the space of Retzius, between the transverse fascia anteriorly and the peritoneum posteriorly.
Urachal cancer is a form of cancer that arises in a structure called the urachus. The urachus is a canal that exists when the fetus is developing before birth. This canal runs from the bladder of the fetus to the belly button (umbilicus). It drains the urinary bladder of the fetus.
In an open (or patent) urachus, there is an opening between the bladder and the belly button (navel). The urachus is a tube between the bladder and the belly button that is present before birth. In most cases, it closes along its full length before the baby is born. An open urachus occurs mostly in infants.
The doctor may:
- Apply silver nitrate to shrink and slowly remove the granuloma. It may take 3 to 6 doctor visits to finish the treatment.
- Use surgical thread to tie off the granuloma at its base. The thread cuts off the blood supply to the granuloma. This will make it shrivel and fall off.
Patent urachus is a rare disorder with an estimated prevalence of 1 to 2 cases per 100,000 deliveries. The urachus is the intra-abdominal remnant of the embryologic allantois, which is seen approximately 16 days after conception as a diverticulum from the caudal wall of the yolk sac.
Umbilical cord cysts are sacs of fluid in the umbilical cord. They're not common—less than 1 in 100 pregnancies (less than 1 percent) has an umbilical cord cyst. Your provider may find an umbilical cord cyst during an ultrasound.
The urogenital sinus evolves into the bladder and urethra. In both male and female fetuses, the allantois has degenerated into the urachus, which usually obliterates in postnatal life to become the median umbilical ligament.
Omphalitis is an infection of the umbilical stump. It typically presents as a superficial cellulitis that can spread to involve the entire abdominal wall and may progress to necrotizing fasciitis, myonecrosis, or systemic disease.
Bladder. This triangle-shaped, hollow organ is located in the lower abdomen. It is held in place by ligaments that are attached to other organs and the pelvic bones. The bladder's walls relax and expand to store urine, and contract and flatten to empty urine through the urethra.
Umbilectomy, also referred to as omphalectomy, is a surgical procedure wherein the umbilicus or the belly button is removed typically due to large umbilical hernias. Large umbilical hernias typically occur in patients who are obese and usually have associated lesions on the skin.
Urachal diverticulum is the rarest type of congenital urachal anomaly (see this term) resulting from the failure of the distal urachus to close at its point of connectivity to the bladder that is usually asymptomatic but can be associated with recurrent urinary tract infections and other complications.
