Summary

Background:
Mesenchymal malignancies are relatively rare tumors with distinct behaviors that are usually surgically removal. However, it is sometimes impossible to perform such surgery according to standardized procedures. In particular, surgical removal of intraperitoneal and retroperitoneal tumors differs among individuals.

Case reports:
We present two cases with intra-abdominal and retroperitoneal sarcomas who were treated at our comprehensive oncology center. The first patient was a 36-year-old male who was initially diagnosed with a tumor in the subrenal space that measured 95 × 90 × 140 mm, contacted the inferior vena cava and right kidney, and had the same blood supply as the upper pole of the right kidney. Primary histological analysis indicated that the tumor was a schwannoma. After further examinations, the tumor was removed and the right kidney was preserved. A ganglioneuroblastoma was diagnosed based on definitive histological analysis. Adjuvant radiotherapy was administered to the tumor bed. The patient is disease-free at 1 year after resection. The second patient was a 52-year-old male who was diagnosed with a liposarcoma in the retroperitoneal space that measured 50 × 36 × 15 cm and weighed 14 kg upon resection. Resection involved left-side nephrectomy and adrenalectomy. Adjuvant chemotherapy with IFO/ADM was administered. A recurrence in the tumor bed was resected 31 months after the primary resection. Three new foci appeared in the retroperitoneal space after another 18 months and were removed. Another recurrence in the left funiculus was removed after a further 6 months. The patient has been disease-free for 3 months.

Conclusions:
Treatment of soft tissue sarcoma is complex and should be performed at a comprehensive oncology center if possible. Preoperative biopsy is essential.
