Abstract
Primary retroperitoneal serous cyst adenomas (PRSCs) are extremely rare thin-walled cystic lesions whose pathogenesis is not well understood. Clinical presentation varies depending on the lesion's size and location, i.e., larger lesions compress adjacent organs, giving the impression of malignancy. Although advances in imaging techniques enable to identify various characteristics of retroperitoneal cystic lesions, there are no pathognomonic signs to confirm the diagnosis. The exact diagnosis is based on the histology after complete surgical excision. An open surgical approach is considered the traditional method of complete resection; however, laparoscopic techniques have increasingly been employed. Diagnostic aspiration is discouraged due to the potential risk of seeding if the lesion is malignant. We present the case of a 51-year-old woman who underwent complete excision of a large right retroperitoneal cyst, histologically confirmed as PRSC with a review of the background and management options of this phenomenon.

Abstract
Mucinous neoplasms are commonly seen in the ovaries and pancreas. Their occurrence in the retroperitoneum is uncommon. We present a case of a retroperitoneal mucinous cystadenocarcinoma in a 54-year-old female who presented with right flank pain. Imaging demonstrated an 8.6 × 7.9 cm mass at the anterior surface of the lower pole of the right kidney, suspicious for renal cell carcinoma. Serum tumor markers carbohydrate antigen 19-9 (CA 19-9) and cancer embryonic antigen (CEA) were within normal limits, and cancer antigen 125 (CA 125) was elevated. Surgical resection of the mass was performed. Intraoperatively, the mass was noted to lie in the retroperitoneum, unattached to the kidney. On gross examination, a 10.0 × 7.0 × 7.0 cm unilocular cystic structure with red-brown mucoid material was present. The inner lining was mostly smooth with areas of excrescences, covering less than 5% of the surface area. Microscopic examination showed cystic areas lined by mucinous epithelium with an underlying ovarian-type stroma. Solid areas showed features of a borderline papillary mucinous tumor with invasive carcinoma. A diagnosis of mucinous cystadenocarcinoma was made. Their occurrence in the retroperitoneum is unusual. Although rare, this entity should always be considered in the differential diagnosis of retroperitoneal cystic lesions.

Abstract
Introduction Primary retroperitoneal mucinous cystadenoma is an extremely uncommon tumor occurring mostly in females. The histogenesis of PRMC remains unclear and Open surgery is the most impressive treatment. Case presentation We present a 20-year-old Iranian woman with history of intermittent abdominal pain. In physical examination, her abdomen had a mildly asymmetrical distention and a round shape mass was palpated in right abdomen also she had a mild tenderness in right abdomen. Radiologic assessment revealed a right retroperitoneal smooth cystic mass (20 × 15 cm) without invasive features. The patient underwent complete surgical excision of the tumor by a laparotomic approach because of its size. The lesion was gently dissected from the contiguous organs and removed completely without spillage of its content. In microscopic investigations, sections showed a unilocular cyst with fibrous wall lined via monolayered bland looking columnar mucinous epithelium and no atypia or stromal invasion was presented. Diagnosis of a PRMC was made. The patient has discharged without any complications in 2 days' postoperative course. Discussion Generally, cysts are asymptomatic and are found fortuitously after a routine checkup assessment. Symptoms and signs related to this cyst are mainly because of their huge size and compression effect. Radiological assessments are effective in specifying the lesion preoperatively; although, the final diagnosis always needs histopathological verification. Conclusion When the tumor is diagnosed, full resection should be considered because of the infectious or malignant potential of the tumor. Full resection of retroperitoneal mucinous cystadenoma because of the infectious or malignant potential of the tumor Histological and macroscopical likeness of primary retroperitoneal cystadenoma to ovarian mucinous cystadenoma CK7 and CA125 positivity in retroperitoneal mucinous cystadenoma because of its Mullerian origin Symptoms and signs related to the cyst mainly because of its huge size and compression effect

Abstract
Mixed serous and mucinous retroperitoneal cyst adenoma is an extremely rare condition as most of the reported cases in the literature are primary retroperitoneal mucinous cystadenomas and primary retroperitoneal serous cystadenomas. They are initially asymptomatic and become symptomatic gradually depending on their size and anatomical extension and location. We report a 49-year-old woman with a history of right-side abdomen pain for a few years. Diagnostic images revealed a large retroperitoneal cystic lesion. A laparoscopic resection was performed without spillage. The patient was discharged without complication postoperatively and no recurrence on follow-up. Surgical excision, either open/or laparoscopic without any spillage, remains the most effective and appropriate treatment for this lesion.

Abstract
Primary retroperitoneal mucinous cystadenoma (PRMC) is a rare tumour. It was first reported in 1965, and since then, less than 100 cases have been reported. It is cystic in nature and most commonly affects the female population. It becomes symptomatic in later stages due to its mass effect, making the diagnosis challenging in its early asymptomatic stage. We report a case of a 32-year-old female who presented with abdominal pain and a mass in left iliac fossa. Diagnostic imaging revealed a large cystic lesion in retroperitoneum. A midline laparotomy was performed, and a complete surgical excision was accomplished without any spillage. Surgical histology confirmed the diagnosis of PRMC. The patient was discharged on postoperative day 2. There was no evidence of tumour recurrence on repeat imaging at 90-day follow-up. Surgical approach, with complete resection and without any spillage, remains the most effective and appropriate treatment for this tumour.

Abstract
Primary retroperitoneal mucinous cystadenomas (PRMC) are rare benign neoplasms with only 55 documented cases in the English literature so far. A 19-year-old female exhibited hirsutism and was found to have a cystic mass measuring 5.8 cm × 3.9 cm × 5.8 cm in the left retroperitoneum. During subsequent work up, a high pre-operative value of dehydroepiandrosterone sulfate (DHEA-S) was noted. The patient was referred to surgical oncology and underwent an uneventful laparoscopic cystectomy. Pathology classified the cyst as PRMC. Post-operatively, the patient's DHEA-S levels normalized, though there was no appreciable decrease in the patient's hirsutism in the short-term follow-up. The origin of PRMC is uncertain. Due to their unknown biological potential, surgical resection is usually recommended. To the best of our knowledge, this is the first report documenting a PRMC and elevated levels of androgens in conjunction with hirsutism.

Abstract
Primary retroperitoneal mucinous cystic neoplasms (PRMCN) with borderline malignancy are exceptionally rare tumours with lack of pathognomonic clinical and imaging-specific features. Here, we report a case of PRMCN with borderline malignancy in a 62-year-old woman who presented with abdominal pain. Imaging studies revealed a well-defined cystic mass on the right flank in close relation with the cecum and caecal appendix, without other findings suggestive of malignancy. A possible diagnosis of an ovarian epithelial tumour was ruled out intraoperatively. After surgical excision, microscopic examination allowed the final diagnosis. As there is no evidence of disease during follow-up, complete tumour resection without cystic rupture appears to be the best therapeutic option. Thus, although rare, this tumour should be considered when imaging findings suggest an ovarian mucinous neoplasm in women with normal ovaries. An international registry for rare tumours and longer follow-ups may contribute for more consistent approach for managing these patients.

Abstract
Primary retroperitoneal mucinous cystadenoma (PRMC) is a rare cystic lesion occurring mostly in women with a histological analogy to ovarian mucinous cystadenoma. The tumor is difficult to detect during early stages because it causes symptoms only when it grows large enough to be palpable or to displace the adjacent internal organs. The primary treatment is resection, but the optimal surgical approach remains poorly known. We report the case of a 41-year-old woman who complained of right-sided intermittent abdominal pain. Imaging studies revealed a right retroperitoneal smooth cystic lesion (50 mm) without invasive features. Laparoscopic resection was then performed. During surgery, a right retroperitoneal mass with no connection to neighboring tissues was found. The tumor, wrapped by retroperitoneal fat tissue, was resected and removed from the body without exposure. Furthermore, histopathological findings indicated PRMC. The patient was discharged without any complications and observed to have no recurrence 6 months postoperatively.

Abstract
Serous cystadenoma, often known as ovarian serous cystadenoma, is one of the common benign ovarian neoplasms. On the other hand, primary retroperitoneal serous cystadenoma is an extremely rare benign entity whose pathogenesis has not been well understood. Clinical presentation and symptomatology vary greatly and are highly dependent on the size and location of the lesion. Primary retroperitoneal serous cystadenomas are homogeneous, unilocular, thin-walled cystic masses. If they grow large enough, they tend to compress and deform adjacent organs, giving clinicians a misimpression of malignant pattern of behavior. Therefore, it is crucial to differentiate benign primary retroperitoneal serous cystadenomas from other epithelial and nonepithelial cystic lesions or masses involving retroperitoneal regions. Management-wise, complete cyst excision without rupture or spillage of the cyst contents is the recommended therapeutic method for primary retroperitoneal serous cystadenomas. This review will highlight the current knowledge on its pathogenesis and discuss its histopathologic features and differential diagnoses from the pathologist's point of view.

Abstract
Primary retroperitoneal serous cystadenomas (PRSCs) are rare cystic lesions whose pathogenesis is currently not well understood. Although the vast majority of tumors are benign, early recognition and resection is necessary to avoid malignant transformation, rupture, and secondary infection. Here we present the case of a 79-year-old woman who presented with confusion, visual hallucinations, and a history of fall. As part of the work-up for abdominal distension, computed tomography scan of the abdomen and pelvis was performed, which revealed a right-sided retroperitoneal cystic lesion measuring 26.6 × 16.7 cm in size. The lesion was resected laparoscopically, and the surgical specimen measured 28 × 17 cm. Histology revealed a serous cystadenoma. The postsurgical course was uneventful, and no radiological recurrence was noted on 3 months follow-up. Very few primary retroperitoneal cystic lesions have been reported in the literature. Most lesions are benign and predominantly occur in females. They may remain asymptomatic for long periods of time and are usually discovered when they reach very large in size. In rare cases, these lesions may have malignant potential. Diagnosis of PRSC should be considered in the differential diagnosis of all retroperitoneal cysts.

Abstract
Retroperitoneal cystic mesothelioma is a very rare lesion. The pathogeny is unclear and establishing a preoperative diagnosis versus others retroperitoneal cystic lesions is difficult. Thus, with increasing experience in laparoscopic retroperitoneal surgery, the use of this approach for exploration of a retroperitoneal mass of unknown origin may provide an alternative to classic open surgery and all the benefits of laparoscopy. We present two cases treated laparoscopycally and review the literature.
