Objective: To investigate the tissue source, clinical diagnosis, treatment and prognosis of primary testicular mucinous cystadenoma (PTMC).
Methods: We retrospectively analyzed the clinical data on a case of PTMC and reviewed relevant literature.
Results: The patient underwent radical resection of the right testis after relevant preoperative examinations. Postoperative pathology indicated mucinous cystadenoma with low-grade intraepithelial neoplasia of the glandular epithelium. No recurrence was observed during an 11-month follow-up.
Conclusions: PTMC is an extremely rare testicular and ovarian surface epithelial tumor, usually benign, rarely malignant. For the treatment of localized PTMC, radical orchiectomy is mostly recommended, while for the cases with invasion, metastasis or recurrence tendency, chemotherapy protocols for ovarian tumors can be considered.
