In July 2021, a 57-year-old woman with a medical history of uterine leiomyosarcoma, diagnosed and excised in 2016, was referred to the Lower Silesian Oncology Center. PET-CT results revealed a nodular lesion of 6.7x5.8x7 cm in the pelvis and a focal lesion in the tail of the pancreas. In August 2021, the patient underwent a laparotomy to remove a retroperitoneal tumor and the vaginal stump. The pancreatic tail tumor was not excised due to the repeated laparotomy and the local advancement of the pelvic tumor. The histopathological examination revealed leiomyosarcoma G2 and infiltration of leiomyosarcoma in the sigmoid colon. Subsequently, a median relaparotomy was performed to excise the tail tumor, and an examination of the postoperative material revealed metastatic leiomyosarcoma (fig. 1). The patient was offered adjuvant doxorubicin chemotherapy but refused treatment. Radical surgery is recommended to treat retroperitoneal sarcomas, and complete cross resection is associated with improved survival [1, 2]. Adjuvant therapy typically involves doxorubicin or ifosfamide chemotherapy [2]. Incomplete mass removal should not be performed if the tumor is unresectable, as it worsens the patient’s prognosis.
