“…Primary mucinous cystadenomas are extremely rare and their histogenesis is not understood completely [5,6]. This pathology tends to be more frequent in females, and it is commonly accepted that invagination of the peritoneal mesothelium undergoes mucinous metaplasia and further cystic formation.…”

Mucinous cystadenoma of the retroperitoneum, laparoscopy or an open approach? Two case reports and review of the literature

Big cystic lesions of the retroperitoneum are rare entities. Most of the cases involved females of reproductive age and were related to ovarian structures. The recommended treatment is surgery, and more than 90% of the reported cases were resected in an open midline abdominal incision. We present two patients who were referred to our clinic due to abdominal mass that was causing vague abdominal pain. Homogenic retroperitoneal cystic mass was demonstrated on computerized tomography (CT). One was resected by laparoscopy and the other by laparotomy, both revealed a mucinous cystadenoma of the retroperitoneum. A review of the literature is also presented.

“…Mü-sinöz tümörlerin büyüme süreci sırasında retroperitonda sürük-lenen multipotansiyel mezotel hücrelerinden kaynaklandığı teorisi bir başka kabul gören mekanizmadır. Bu hücreler müsinöz metaplaziye uğrar, kistik müsinöz inklüzyonlarla birlikte sitolojik değişiklikleri ve malign fenotipi oluştururlar [7]. Tedavi konusu da net değildir.…”

ÖzetRetroperitoneal primer müsinöz tümörler son derece nadir görülürler. Bugüne kadar literatürde çoğu kadın olan primer retroperitoneal müsinöz kistadenokarsinom (PRMK)'lu 52 vaka bildirilmiştir. Bizim hastamız şimdiye kadar bilinen 5. erkek vakadır. 57 yaşında erkek hasta yaklaşık 2 yıldır olan müphem karın ağrı-sı şikayetleriyle başvurdu. Bilgisayarlı tomografisinde sağ iliak fossadan superiora uzanan psoas kası komşuluğunda batın duvarı altında 12x9,5 cm kistik kitle lezyonu izlendi. Laparatomide retroperitoneal alandaki kitlenin iliopsoas kası içi-ne invaze olduğu görüldü. Patoloji sonucu müsinöz kistadenokarsinom olarak raporlandı. Tümörün klinik seyrinin yavaş olması ve adjuvan tedavinin standart olmamasından dolayı postoperatif kemoterapi planlanmayan asemptomatik hasta takibe alındı. PRMK'un klinik seyri genellikle indolen olmasına rağmen agresif seyir de gösterebilir. Patogenezi net değildir. Tedavi konusu da tartışmalıdır. Tanı ve tedavi için cerrahi eksizyon yapılmalıdır ancak adjuvan kemoterapi konusunda bilgiler sınırlıdır. Anahtar KelimelerRetroperitoneal Neoplazmlar; Kistadenokarsinom; Müsinöz Abstract Retroperitoneal primary mucinous tumor is an extremely rare malignancy. To date, only 52 cases of primary retroperitoneal mucinous cystadenocarcinoma (PRMC) have been reported in the literature, with the majority being women. Our patient is the 5th known male case. A 57-year-old male patient presented with a two year history of an undefined abdominal pain.Computed tomography demonstrated a 12 x 9.5 cm cystic mass lesion extending superiorly from right iliac fossa, while localizing below the abdominal wall and close to the psoas muscle. According to the laparotomy, iliopsoas muscle was infiltrated by the mass in the retroperitoneal region. Pathological diagnosis was mucinous cystadenocarcinoma . The asymptomatic patient was followed up without applying an adjuvant chemotherapy, since the clinical course of the tumor is known to be slow and postoperative therapy is not recognized as a standardized treatment. The clinical course of PRMC is generally indolent, however, it may manifest an aggressive course, as well. It has no definitive and clear pathogenesis. The treatment is contentious, as well. Diagnosis and treatment require surgical excision but data on adjuvant chemotherapy is limited.

“…Mucinous cystadenomas are homogenous and well-defined unilocular cysts found in women with normal ovaries (26)(27)(28)(29). The pathogenesis is unclear, although it has been suggested that these lesions arise from invagination of the peritoneum, with consequent mucinous metaplasia and cyst formation.…”

Detection and management of retroperitoneal cystic lesions: A case report and review of the literature

et al. 2017

Abstract. The identification of cystic lesions within the retroperitoneal space is a rare event that poses clinicians the challenge of a difficult diagnosis and disease management. Retroperitoneal cystic lesions account for a group of lesions that range from common benign lesions (e.g., lymphoceles developing as a surgical complication) to rare aggressive malignant neoplasms. Currently, in the majority of cases, image-guided procedures allow for a pathological diagnosis to be achieved in these challenging lesions, thus offering the chance of an appropriate treatment; however, the overall clinical assessment of retroperitoneal cysts is highly demanding. The present study reports the management of a representative clinical case, presenting with a voluminous cystic mass able to dislocate cave vein, whose diagnosis was preceded by a deep vein thrombosis. Computed tomography-scan and ultrasound guided percutaneous drainage were performed to achieve the diagnosis. Following the discussion of the current case report, a review of the pathological and radiological characteristics of retroperitoneal cystic lesions is presented.
