Objective: Primary testicular mucinous cystadenoma (PTMC) is one of the rarest ‘ovarian type’ tumors which originating from surface epithelium. We aimed to present a case which was finally diagnosed as PTMC and try to analysis the clinical characteristics of this condition.

Methods: A 21-year-old male got into our hospital with a chief complain of aggressively enlarging right testis for more than 1 year. The patient denied of any malaise in his testes, epididymis and scrotum, like pain, fever, mass, nodule or ulceration, and any etiological factors, such as infection or trauma. Further, ultrasonography of scrotum was subsequently conducted which reported that an anechoic mass measured to be about 54 mm × 35 mm × 52 mm could be found at the lower polar of right testis except for a few normal testicular tissue at its upper polar. Multiple divisions accompanying with spot blood flow signal could be also discovered in this mass, and a teratoma was subsequently suspected before operation.

Results: A right inguinal radical orchiectomy was carried out and mucinous cystadenoma without invasion of spermatic cord was pathologically diagnosed. Additionally, recurrence was not observed with a follow-up of 3 months. Furthermore, except for our case, only five patients have been diagnosed as benign PTMC based on our search of all English literature from PubMed. The medium age of these patients was 43 (range: 35–55), and lesions of four patients were located at the right side. However, all patients were reported with satisfactory results without of recurrence.

Conclusions: PTMC was a very rare disease with favorable prognosis. Our case would be the youngest based on literature research. However, to date, it is still very limited about the understanding of this disease.
