How is umbilical cord formed?

Simply put, umbilical polyp means that a child has an abnormal polyp growing in the navel. Severe umbilical polyps should even be removed immediately. When children show this symptom, many parents are very anxious. The umbilical cord of a newborn is related to the baby's health. The appearance of umbilical cord fungus can cause infection, so parents should pay attention to it. Now let me give you some basic information about the symptoms of umbilical cord hair in newborns and how it is formed.

1. Source

The fetus is connected to the mother's placenta through the umbilical cord. The connection between the base of the umbilical cord and the middle of the fetal abdomen is called the navel. The umbilical cord contains the umbilical vein and umbilical artery (which are connected to the blood vessels in the fetus' body and closed after birth to become the round ligament of the liver), as well as the yolk duct (which is connected to the fetus's small intestine) and the urachus (which is connected to the fetus's bladder).

Under normal circumstances, structures such as the yolk duct become blocked, fibrotic, or disappear during fetal development and after umbilical cord cutting, and only a skin scar depression - the umbilicus - remains.

Umbilical cord polyp is a polyp-like growth that appears in the umbilicus of children when the distal mucosa (intestinal mucosa) has not completely disappeared after the yolk duct is blocked.

"Umbilical cord granuloma" is called "umbilical granuloma" in some literature.

granuloma). In fact, analyzing from the source of umbilical cord trichomoniasis, it is a congenital malformation rather than a granuloma. Perhaps because the commonly used term "umbilical cord" and its English translation cannot be found in medical professional dictionaries, but only "umbilical cord granuloma" and its English translation is available, these authors believe that umbilical cord granuloma is equivalent to umbilical cord granuloma. In fact, the synonym of "umbilical polyp" is "umbilical yolk duct polyp".

The term "umbilical polyp" can be found in medical dictionaries.

3. Umbilical granuloma refers to a polyp-like growth formed due to the stimulation of foreign bodies (such as talcum powder, blood scab) or infection of the unhealed wound after umbilical cord cutting.

Cherry red, smooth and moist surface, polyp-like. The smaller ones are about the size of mung beans, while the larger ones can exceed 0.5 cm in diameter, with some roots becoming thinner to form stalks.

5. Organizational form:

The squamous epithelium of the umbilical skin is connected to the embryonic remnant intestinal mucosa. Normally, the umbilical cord of a newborn falls off within two weeks of birth. However, abnormalities may also occur in the umbilicus of newborns and should be diagnosed and treated promptly.
