Background: PRMC is a very rare benign tumor of the abdominal cavity that usually occurs in women, and PRMC demonstrate no specific findings on CT. There are many reports on the differential diagnosis and discussion of PRMC imaging, but there are few reports on the treatment of dedifferentiated PRMC using laparoscopic resection and postoperative follow-up.

Teratomas are bizarre neoplasms derived from embryonic tissues that are typically found only in the gonadal and sacrococcygeal regions of adults. Retroperitoneal teratomas are rare and present challenging management options. We report here the case of a histologically unusual retroperitoneal tumor detected on computed tomography during the workup of abdominal pain in a 32-year-old male. The evaluation and treatment of this condition and a review of the literature are included in this paper.

Primary retroperitoneal mucinous cystic neoplasms are very rare, especially in men. To our knowledge, only 13 cases of such neoplasms have been reported in men to date. The most common type is the primary retroperitoneal mucinous cystadenoma, which almost invariably affects females. Most patients present with non-specific symptoms. In this case report, we will describe a case of a 53 year old male patient who presented with raised CEA tumour marker and vague right sided abdominal discomfort. A computed tomography (CT) scan was performed, which revealed a 4.9 × 4.7 × 7.5 cm lobulated retroperitoneal cystic lesion abutting the posterior wall of the mid ascending colon. A laparoscopic excision was eventually performed with complete removal of the retroperitoneal cystic lesion. Subsequent histological assessment confirmed the diagnosis of a primary retroperitoneal mucinous cystadenoma with borderline malignancy. On comparison with a prior CT scan performed about seven and a half years earlier, we managed to derive a doubling rate of about 626 days, which is the first reported case in English literature to document the growth rate of such a tumour. The patient has since been discharged well, with no evidence of tumour recurrence on an interval CT scan.

Introduction: Primary retroperitoneal mucinous cystadenoma (PRMC) and its malignant variant – cystadenocarcinoma are extremely rare tumors known only from case studies and reviews. PRMC is a cystic tumor of the retroperitoneum, which remains asymptomatic for a long time and can reach significant proportions. It occurs mainly in women. Case report: We present the case of a 38-year-old healthy woman with diagnosed resistance in the right mesogastrium during a c-section. The delivery was terminated without a surgical intervention. The above mentioned resistance was examined further by ultrasound, computed tomography and magnetic resonance imaging. All imaging examinations showed a solid – cystic bilocular expansion, which looked like a mesenteric cyst in the right paracolic area. The patient was asymptomatic at all times, with only a palpable resistance of the abdominal wall. In November 2020, the patient underwent an elective surgery – extirpation of the cystic tumor and prophylactic appendectomy. The operation was performed classically, via midline laparotomy without perioperative perforation of the cystic tumor and without complications in the postoperative period. The histopathological examination showed a malignant variant of PRMC. So far, the patient remains free of any problems and is followed at the department of oncology. Conclusion: The goal of treatment is to achieve complete surgical removal of the tumor without its perioperative perforation. Due to the rare occurrence of the disease, there are no guidelines for the diagnosis and treatment of PRMC. Precisely because PRMC is a rare tumor, it should be part of the differential diagnosis of cystic tumors of the retroperitoneum, especially when young women are concerned.
