Primary mucinous cystadenoma originating from testis: a case report and review of literature

Primary testicular mucinous cystadenoma (PTMC) is one of the rarest ‘ovarian type’ tumors originating from surface epithelium. We aimed to present a 21-year old case and try to analysis the clinical characteristics of this condition. In our case, a right radical orchiectomy was carried out and mucinous cystadenoma was finally diagnosed based on pathology. Additionally, recurrence was not observed with a follow-up of 6 months. Furthermore, except for our case, only five patients have been diagnosed as benign PTMC based on our search of all English literature. Our case would be the youngest based on literature research. However, it is still very limited about understanding of this disease.
