Retroperitoneal lymphangioma

In daily life, people will develop various fibroids inside their bodies, most of which are benign. Common ones include uterine fibroids, hepatic hemangioma, retroperitoneal lymphangioma, etc. Today, the editor will take you to learn about the relevant knowledge about retroperitoneal lymphangioma. People with retroperitoneal lymphangioma will not feel any discomfort in the early stage. Only when the tumor becomes larger in the later stage will people have symptoms such as abdominal pain and back pain. Once retroperitoneal lymphangioma is diagnosed, timely treatment is required, otherwise it may lead to cancer in the later stages. Specific information about retroperitoneal lymphangioma is introduced.

Retroperitoneal lymphangioma is a benign tumor with an unclear pathogenesis. Most cases are congenital, with 90% of cases presenting before the age of 2 years, with an equal ratio of males to females. The disease occurs in the peritoneum, accounting for about 5%. The tumor is a unilocular or multilocular cystic tumor with clear boundaries and fine separations, and can be distributed along the inter-organ spaces. The tumor is composed of dilated lymphatic vessels with varying lumens and thin walls composed of fibrous tissue. The walls of the vessels are lined with flat endothelial cells, and the interstitial fibrous tissue between the walls proliferates. A large number of lymphocytes can be seen gathering and forming lymphoid follicles, making the interstitium wider.

Retroperitoneal lymphangioma usually has no obvious symptoms in the early stages. As the cyst grows and exerts pressure on the abdominal organs, corresponding symptoms will appear, such as abdominal mass, abdominal pain, vomiting, abdominal distension, low back pain, etc., which are mostly non-specific manifestations. Because the cyst is located deep and deforms after compression, it is often difficult for patients to find it. It is usually discovered during physical examination or imaging examination. Physical examination revealed a soft, fluctuant mass.

The main treatment is surgical resection. This disease is a benign lesion and can be cured after surgical resection. Among them, unilocular tumors with small size and no adhesion to surrounding organs are easier to eradicate, while multilocular tumors with large size and severe adhesions are more difficult to eradicate, and damage to retroperitoneal organs should be avoided during surgery.
