“…Our patient is disease free 3 years after surgery. In fact due to the disease rarity, the impact of the different treatment modalities cannot be evaluated until more cases been reported and data on prognosis become clear [6].…”

We present a new case of leiomyosarcoma, a very rare clinical entity, arising from the renal pelvis. The primary diagnosis, based on asymptomatic gross hematuria and imaging findings, was tumor of the left kidney. After a left radical nephro-ureterectomy, histology confirmed a leiomyosarcoma of the renal pelvis. No adjuvant treatment was provided and the patient remains healthy 3 years after surgery.

“…Renal LMSs develop from the renal structures that have smooth muscle layers, such as the renal capsule, pelvis and vein. The most frequent site is the renal vein [29], being also the most common location for extracaval LMSs, followed by renal capsule [30] and renal pelvis [31]. Fifteen percent of all soft tissue sarcomas are located in the retroperitoneum, 20% of them being LMSs.…”

Leiomyosarcoma (LMS) of the inferior vena cava (IVC) is a rare malignant tumor, accounting for 2% of all LMSs. Less than 400 cases have been reported in literature. Computed tomography (CT) is the most accurate imaging method in assessing the location of the tumor within the IVC and magnetic resonance imaging (MRI) accurately identifies its extent and the potential for surgical resection. We present the case of a patient with inferior vena cava leiomyosarcoma (IVCL), for whom the pathological diagnosis was different from the initially expected one, the tumor appearance on pre-operative imaging mimicking renal cell carcinoma. The intraoperative difficulty of approaching renal hilum and IVC was a factor suggesting the vascular origin of the tumor, which was confirmed at pathological analysis. The extensive defect in the IVC after tumor excision led to the decision of complete transverse suturing of IVC, as significant collateral venous circulation was already present. Because IVCL is a rare disease, there is scarce data regarding the prognosis and treatment options. Long-term survival depends on the extent of the surgery. The need of vascular reconstruction is not always mandatory. Despite high recurrence rates, no consensus regarding adjuvant treatment exists yet. A multidisciplinary approach including surgical oncologists and vascular surgeons is mandatory to achieve the best patient outcomes. Perioperative planning, coordination and adherence to oncological techniques are critical.

“…Опухоль НПВ следует отличать от лейомиосаркомы, возникающей из окружающих структур, главным образом из почки и забрюшинного пространства. Наиболее частым местом возникновения являются почечная вена [12], почечная капсула [13] и почечная лоханка [14]. Пятнадцать процентов всех сарком мягких тканей локализуются в забрюшинном пространстве, 20 % из них имеют строение лейомиосаркомы.…”

Leiomyosarcoma of the inferior vena cava (IVC) is a rare malignant tumor observed in 2 % of all leiomyosarcomas. Less than 400 cases are described in the literature, in Russian publications not more than 30. Computed tomography is the most accurate diagnostic method for determination of tumor location, presence or absence of thrombosis and its severity, evaluation of resectability. We present a case of a patient with leiomyosarcoma of the IVC with preoperative diagnosis of adrenocortical carcinoma of the right adrenal gland with tumor thrombosis of the IVC and tumor advancement into the right kidney. During intraoperative revision the tumor was evaluated as primary leiomyosarcoma of the IVC with thrombosis of the iliac veins up to the retrohepatic segment of the IVC and advancement into the right adrenal gland and vascular structures of the right kidney and its pole which was confirmed by histological examination. Surgery is the main method of treatment of leiomyosarcoma of the IVC. Long-term results depend on the volume and radicality of operation. Reconstruction of the IVC is not always necessary. Despite high recurrence rate, there is no consensus on adjuvant treatment. The best results are achieved through interdisciplinary approach involving an oncological surgeon, chemotherapist, vascular surgeon, anesthesiologist. Perioperative planning, coordination, and adherence to oncological methods are crucial for recovery.
