A patient with large retroperitoneal liposarcoma - a challenge for an anesthesiologist

Retroperitoneal liposarcoma is a rare type of tumor characterized by slow growth and nonspecific symptoms, and is usually diagnosed at an advanced stage. Patients with huge retroperitoneal liposarcoma have a high risk of developing perioperative complications, and require special preoperative preparation and a carefully planned anesthetic approach. We present the case of a 57-year-old man, who was diagnosed with a huge retroperitoneal liposarcoma, 70 cm in diameter, weighing 30.4 kg and planned for surgical resection of the tumor under general anesthesia. Perioperative treatment and anesthesia for this patient were a great challenge for the anesthesiologist. However, due to preoperative preparation, monitoring and fluid replacement, hemodynamic and respiratory stability of the patient was maintained perioperatively.

Huge retroperitoneal liposarcoma with renal involvement requires nephrectomy: A case report and literature review.

A 60-year-old female visited Guihang Guiyang Hospital (Guiyang, China). She presented with abdominal pain in the right side for the previous 2-months, with a touchable mass identified for the previous 1-month. Computed tomography with magnetic resonance imaging revealed a huge mass in the right abdomen. The diagnosis of well-differentiated retroperitoneal liposarcoma with renal involvement was made. During surgery, the tumor was removed, including the fatty renal capsule; however, the kidney was preserved. It is currently debatable whether resection of adjacent organs is required to obtain the negative margins. Conventional viewpoints advise that multi-organ resection is required in order to obtain the negative-margin. However, even if an R0 resection is achieved, the local recurrence rate remains markedly high. Additionally, the complications of organ resection have more impact on patients. Radiotherapy and chemotherapy are an important adjuvant method for these patients. In conclusion, retroperitoneal liposarcoma is a rare disease with a high rate of recurrence. Complete resection is the predominant treatment; however, combined resection of adjacent organs must be considered.

Rare Synchronous Primary Large B-cell Gastric Lymphoma and Huge Retroperitoneal Liposarcoma with Inguinal Hernia in Chronic Hepatitis B Patient

Multiple primary neoplasms with synchronous or metachronous presentation are rare, although the incidence has recently increased because of several factors. We present the case of a 53-year-old patient with chronic hepatitis B who presented with abdominal mass, mild abdominal pain, and inguinal hernia. Computed tomography imaging demonstrated diffuse thickening of the gastric antral wall, together with a huge heterogeneous abdominal mass with predominant fat attenuation with septa that showed mild enhancement on contrast-enhanced scans. Distal gastrectomy and wide resection of the retroperitoneal mass was performed. Pathology exam led to a diagnosis of diffuse large B-cell gastric lymphoma with retroperitoneal liposarcoma. This is a rare case of a primary gastric lymphoma with another primary (sarcomatous) malignancy occurring synchronously in same patient.

A CASE OF RETROPERITONEAL LIPOSARCOMA INFILTRATED INTO THE DESCENDING COLON AND FORMED AN ULCER

We encountered a patient with a huge retroperitoneal liposarcoma that infiltrated into the descending colon and formed an ulcer. A 77-year-old man was admitted to the hospital because of bloody stool, fever and general weakness. On abdominal ultrasonography and abdominal CT, a tumor pressing the pancreas, left kidney and colon was detected in the left retroperitoneal cavity. Leakage of contrast medium from the descending colon was observed on a barium-enema study, indicating that an ulcer was formed due to tumor infiltration. On examination of the excised specimen, the tumor measured 10×11×10cm and the internal tissue was necrotized. The ulcerative tumor infiltrated into the descending colon, forming a fistula. The tumor was histologically typed as mixed liposarcoma. Retroperitoneal liposarcoma is discovered as a huge mass in many cases, and thus associated resection is frequently demanded due to infiltration into and compression of other organs. However, it is rare that the tumor infiltrates into the colon, forming an ulcer. Therefore, we report this case with a review of the literature.

Rare case of huge retroperitoneal liposarcoma presenting as a gynaecological problem

A large retroperitoneal liposarcoma presented clinically as an ovarian tumour in an infertile woman. The importance of computed tomography in the differential diagnosis and the appropriate management of retroperitoneal liposarcoma is presented with a review of the relevant literature.

A CASE OF HUGE RETROPERITONEAL LIPOSARCOMA

This time, we experienced a huge retroperitoneal liposarcoma (hereafter to as the present disease). The present disease commonly lacks in clinical manifestations due to the anatomical situation and is often discovered after developing to a huge tumor.For the diagnosis of the present disease, CT and MRI were useful. In CT. it presented as a low density tumor showing the CT values of -13-99 which are about the same as those of fat and the inside was heterogeneous without enhancement by the contrast medium. In MRI, it was heterogeneous of a low density in T1 image, a part of which showed a shelflike high intensity. In Gd-DTPA, an irregular contrast enhancement was observed at the marginal area. Angiography revealed a hypovascular tumor nourished mostly by arborizations from capsular artery system.Histopathologically, it was a mixture of well differentiated and myxoid types.

A CASE OF HUGE RETROPERITONEAL LIPOSARCOMA

Retroperitoneal liposarcoma is a relatively rare disease.Recently we treated a case of a huge retroperitoneal liposarcoma weighing 9.0 kg. This case involved a 48-year-old female who complained of abdominal swelling and was admitted to our hospital. We diagnosed a retroperitoneal tumor and performed surgery.At operation, a huge orange-yellow tumor with a soft elastic consistency occupied most of the intra-abdominal space. As the tumor was wrapped in a pseudocapsule, we easily separated it from the surrounding organs except for the left adrenal gland. Eventually we resected it completely with a part of the left adrenal gland.The tumor size was 42×30×15 cm and the weight was 9.0 kg. In histological examination, some tumor cells were observed to be spindle shaped, some ones were star-like and others were round. The interstitial tissue was myxomatous and many blood vessels were included. A few lipoblast cells existed and most tumor cells had granules positive to oil-red-O stain. No tumor cells were seen in the left adrenal gland. The final diagnosis was myxoid-type liposarcoma. The total number of cases of liposarcoma in Japan is 178. However only four of these hal tumors weighing more than 10 kg which could be resected. The capsule of the liposarcoma is a so-called pseudocapsule and it causes frequent invasion and difficulty of complete resection. In our case, a very small part of the pseudocapsule may have remained so that we must carefully follow up the patient's course.

Computerized tomography of a large retroperitoneal liposarcoma

A case of a huge retroperitoneal liposarcoma that was diagnosed with computerized tomography is presented. Conventional radiographic studies demonstrated organ displacement. Computerized tomography confirmed the retroperitoneal locationand attenuation coefficient numbers consistent with a liposarcoma. The availability of CT and the distinctive appearance of these unusual tumors should allow for future histologic diagnoses preoperatively.
