Primary retroperitoneal mucinous neoplasms (PRMCNs) are infrequent and have a remarkable prevalence in women, with a ratio of 9.4:1 compared to men. This statistic is especially relevant today, as this condition was previously believed to be exclusive to women. We present the clinical case of a 60-year-old male patient with a retroperitoneal tumor. A retroperitoneal tumor resection was performed, revealing a mucinous, lobulated tumor surrounding the ureter and displacing the right renal unit and great vessels. As physicians, it is important to take into account this pathology and not to exclude its incidence in men. According to an article published in 2019, 19 cases of PRMCN have been reported, of which two correspond to men. In conclusion, primary retroperitoneal mucinous cystic neoplasms present a challenge for pre-operative management due to the lack of specific data available on this entity.
