“…The time of these symptoms’ occurrence varies from several months for sarcomas to years for benign tumors. Patients usually visit a physician when they discover a pathological mass in the abdomen (60.4%) [1]. In the present case her first symptoms (abdominal distension and limb edema) occurred 15 years after discovering the tumor.…”

Retroperitoneal hemangiomas are very rare. This paper presents the case of a 71-year-old female patient with giant cavernous hemangioma of the retroperitoneum who underwent surgical treatment for abdominal pain and left lower limb edema. Interventional staged treatment with percutaneous transcatheter arterial embolization prior to surgery was considered. Radical resection of the tumor was performed, which caused the symptoms to abate. Additionally a literature review of cases involving cavernous hemangioma in the retroperitoneal space is presented. No description of retroperitoneal cavernous hemangioma originating from the bowel was found in the analyzed reports.

“…Primary retroperitoneal tumors (PRTs) of vascular origin are a diverse group of rare abdominal neoplasms, both benign and malignant [1]. The most frequent malignant tumors are liposarcoma and leiomyosarcoma, while the most often found benign tumors are lipoma, leiomyoma and cavernous hemangioma [2–5].…”

“…In the presented case, surgical resection was initially deferred due to encasement of the aorta, IVC, origins of the superior mesenteric artery and bilateral renal arteries. Previously, complete resection of the tumor with reconstruction of major vascular structures was shown to be a safe method with acceptable outcome for complete resection of large retroperitoneal tumors including sarcoma (19)(20)(21)(22). However, even in these studies, nephrectomy appeared to be inevitable in order to meet the oncological standards of complete resection (20,22).…”

However, even in these studies, nephrectomy appeared to be inevitable in order to meet the oncological standards of complete resection (20,22). In the case of the present study, considering the bilateral involvement of the origin of renal arteries, nephrectomy would have left the patient requiring lifetime dialysis.…”

Abstract. Ganglioneuromas are slow growing, clinically silent benign tumors for which surgery is considered to be the standard treatment. However, surgical excision in cases where surrounding structures are involved can be challenging. The present study reports a novel technique of ex vivo excision for the management of a retroperitoneal ganglioneuroma in a 21-year old patient, that appeared to be inoperable using standard surgical resection. Preoperative investigations revealed a large tumor with encasement of the origins of the superior mesenteric artery (SMA) and bilateral renal arteries. Initially, to prevent the need to explant the liver, the distal SMA (with takeoff of the replaced common hepatic artery) was anastomosed to the splenic artery. The bulk of the tumor along with the bilateral kidneys was mobilized from the retroperitoneum, and the aorta and inferior vena cava (IVC) were cross-clamped above and below the tumor and divided. The two kidneys were dissected free of the tumor at the back-table and were auto-transplanted in a standard technique following the reconstruction of the aorta and IVC. The patient tolerated surgery well and a one-year postoperative follow-up did not show any sign of tumor recurrence. Although technically demanding, ex vivo resection and auto-transplantation of the involved organs can be introduced as a final option for the treatment of tumors that are un-resectable using standard surgical techniques. IntroductionGanglioneuromas (GNs) are rare, slow-growing benign tumors arising from the sympatho-adrenal neuroendocrine system (1,2). GNs typically occur in children and adolescents, with up to 60% of patients <20 years old at the time of diagnosis. Additionally, females are more likely to be affected than males (3). GNs are the benign ends of a wide spectrum of peripheral neuroblastic tumors, which also include neuroblastoma, ganglioneuroblastoma and ganglioneuroblastoma intermixed (2,4). GN can be diagnosed de novo in healthy patients or in specific cases result from spontaneous or chemo-or radiotherapy induced maturation of less-differentiated neuroblastic tumors (neuroblastoma and ganglioneuroblastoma) (1,5). In addition, certain studies have presented an association between GNs and specific familial diseases including neurofibromatosis type 2 and multiple endocrine neoplasia type 2 (6,7). While GNs can occur anywhere along the sympathetic nervous system, the two most common locations of occurrence are the posterior mediastinum and retroperitoneum (6). Retroperitoneal tumors may originate from the adrenal glands or extra-adrenal tissues (6). There are a limited number of studies reporting tumor occurrence in uncommon locations, including the tongue, bladder, uterus and skin (8-10).Although complete surgical excision is considered to be the treatment of choice in the management of these tumors, occasionally it can be challenging and in specific cases (such as when large tumors are involving the surrounding vital organs) it is not a feasible option. The current case report pre...

“…Leiomyoma and leiomyosarcoma represent one of the various types of primary retroperitoneal masses in adults [1] with an overall incidence of 2.8%; of those, the malignant variant, leiomyosarcoma, is 11.2% [2]. Retroperitoneal leiomyoma often presents a diagnostic challenge as it shares a resemblance with most retroperitoneal smooth muscle tumors in terms of clinical presentation, histology, and steroid/estrogen and progesterone/hormone positivity; moreover, they are considered to be malignant whereas retroperitoneal leiomyoma is not [3].…”

Retroperitoneal myoma and chronic pelvic pain: case report and literature review

et al. 2009

We present a case of a postmenopausal diabetic hypertensive female with a solitary retroperitoneal myoma (2,025 g) and no smooth muscle (myomatic) nodules on visceral and parietal peritoneum. She complained of chronic pelvic pain in absence of internal female genitalia (except uterine cervix), high frequency of urination, pelvic discomfort, and feeling of heaviness. The patient had undergone hysterectomy with bilateral adnexectomies 13 years ago and she had not had any exposure to exogenous hormones during her reproductive and postmenopausal period of life (oral contraception and hormonereplacement therapy). Several suppositions were made, supporting hormonal genesis of myoma with retroperitoneal localization in postmenopausal age and the significance of eventual presence of concomitant metabolic disturbance for its origin in that age was also emphasized. The known risk factors for growth and development of myoma were also affected by the presence of collateral dismetabolic conditions, which influenced and aggravated the disturbed hormonal balance. That is why they could be considered as a possible additional risk factor.
