What causes retroperitoneal cysts?

Retroperitoneal cysts are believed to be benign tumours of retroperitoneum. They often attain large proportions before causing any symptoms. These rare tumours are derived from remnants of embryonal urogenital apparatus which includes tissues of both epithelial and mesothelial origin [1].

What is the treatment of retroperitoneal cyst?

Retroperitoneal cystic lymphangioma is a rare benign tumor. Most patients eventually experience some symptoms that necessitate therapeutic intervention. Excision is the treatment of choice, and some cases of laparoscopic resection have been reported.

What does retroperitoneal mass mean?

Retroperitoneal tumors are rare growths that originate from within the retroperitoneal spaces rather than the major retroperitoneal organs (2). The classification of retroperitoneal tumors can be based on type of tissue origin (3).

What is retroperitoneal cystic mass?

Retroperitoneal cystic teratomas are cystic tumors composed of well-differentiated derivations from at least two of the three germ layers (ectoderm, mesoderm, endoderm). Most patients are female, and the tumor is commonly diagnosed in newborns, who are usually asymptomatic (,6).

What is a retroperitoneal liposarcoma?

Abstract. Retroperitoneal liposarcomas are rare mesenchymal tumors of the retroperitoneum that typically present with advanced disease and often carry a poor prognosis. Because of their rarity and anatomic location, these malignant tumors can cause a diagnostic dilemma and present several therapeutic challenges.

Is retroperitoneal liposarcoma curable?

Retroperitoneal liposarcomas are potentially curable with complete resection of the tumor with negative margins [9] nevertheless complete resection of these tumors is often challenging, as these lesions are very large when diagnosed and may involve many adjacent organs and structures due to the tumor size [2, 6].

What causes Mullerian cyst?

Müllerian cysts: These are another common type of cyst that form as a result of material left behind when a baby develops. They grow anywhere on the vaginal walls and often contain mucus. Gartner’s duct cysts: These can occur when ducts in a developing embryo do not disappear as they should after a baby is born.

How do you get rid of a Mullerian cyst?

The surgical treatments consist of transurethral cyst incision drainage, open cyst resection and laparoscopic cystectomy (14–16). Coppens et al (17) suggested that the treatment of Mullerian duct cysts is most suitable for symptomatic or infertile patients.

What is retroperitoneal sarcoma?

What is retroperitoneal sarcoma? Sarcoma is a rare type of cancer that develops from the body’s connective tissues, such as fat, muscle, blood vessels and fibrous tissue. About 20% of sarcomas develop in the back of the abdomen, also known as the retroperitoneum, next to the kidneys.

How do they remove retroperitoneal lymph nodes?

Retroperitoneal lymph node dissection, commonly referred to as RPLND, is a procedure to remove abdominal lymph nodes to treat testicular cancer, as well as help establish its exact stage. It is usually performed using an incision that extends from just below the breastbone (sternum) to just below the navel.

What is survival rate for retroperitoneal liposarcoma?

Even with complete removal of the liposarcoma, prognosis remains poor. The 5-year survival rate of well-differentiated retroperitoneal liposarcoma is 83%, while it is 20% for the dedifferentiated tumor subtype (4). Successful complete resection of retroperitoneal liposarcoma may increase the 5-year survival rate.
