“…Furthermore, the PRMC resembles ovarian mucinous cystadenomas. 1,[5][6][7] This theory would explain why women have higher reported incidence of being diagnosed with PRMCs. 1 The second most commonly referenced theory is that these cysts arise from the invagination of the multipotential mesothelium followed by mucinous metaplasia of the mesothelial cell lining, which gives rise to the mucinous cyst.…”

First Report of Retroperitoneal Mucinous Cystadenoma in a Patient with Hirsutism

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 x 3.9 cm x 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.

“…Lee at al reviewed 56 cases of primary cystic mucinous neoplasms and reported that the presence of solid nodules in the cyst was the only statistically significant predictive factor of malignancy (cystadenocarcinoma). 19 Diagnostic fluid aspiration is discouraged due to concerns of seeding during the procedure if the lesion is malignant. The treatment of choice is complete surgical excision.…”

Primary retroperitoneal serous cystadenoma (PRSC) is an extremely uncommon lesion of retroperitoneum. Very few case reports of this entity have been described in the literature. The pathogenesis is not well understood, although one of the proposed hypotheses considers it to be an embryological remnant of the urogenital apparatus with epithelial and mesothelial tissues. 1 These cysts oftentimes attain very large size before becoming symptomatic. Our case review is focused on the diagnostic, therapeutic, and pathological findings of this rare entity. Case PresentationA 79-year-old female presented to the emergency room with confusion, agitation, and visual hallucinations after sustaining a fall. Although the patient was a poor historian, her family members did not report prior history of abdominal complaints including trauma, fever, weight loss, abdominal mass, or surgery. Abdominal examination revealed soft, nontender, palpable fullness in the paraumbilical region. Gastroenterology service was consulted for a nontender AbstractPrimary 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 Â 16.7 cm in size. The lesion was resected laparoscopically, and the surgical specimen measured 28 Â 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.

“…Malignant PRCL such as mucinous cystadenoma and cystadenocarcinoma, pseudomyxoma retroperitonei and solid neoplasms with cystic transformation (leiomyosarcoma, paraganglioma), are rare [5], [7], [8], [9], [10]. On the contrary, a wide variety of benign retroperitoneal cystic lesions has been described [5], [8], [9], [10], [11], [12], [13], [14], [15], such as müllerian cyst, hydatid cyst, lymphangioma, cystic mesothelioma, cystic teratoma, tailgut cyst, epidermoid cyst, post-traumatic pseudocyst, lymphocele following abdominal surgery, urinoma, hematoma and bronchogenic subdiaphragmatic cyst.…”

“…This is why we consider laparoscopic complete resection should be the treatment of choice for retroperitoneal CM. Only in cases when malignancy is highly suspected, laparotomy should be performed, in order to assure complete excision of the lesion and to avoid spillage of the cyst́s content, risking intraperitoneal or trocar site recurrence [4], [7]. Prognosis after complete resection is usually favourable, although long term follow up must be made, to exclude local recurrence.…”
