A 53-year-old Taiwanese male had several episodes of left epididymitis with hydrocele refractory to antibiotic treatment. Partial epididymectomy plus preventive vasectomy were planned, and, incidentally, an ill-defined nodule was found lying on the tunica vaginalis near the epididymal head. The pathological diagnosis was malignant mesothelioma of the tunica vaginalis testis. Radical orchiectomy with wide excision of the hemi-scrotal wall was performed. So far, there is no evidence of recurrence after more than 3 years of follow-up. Malignant tumor should be considered in the case of recurrent epididymitis refractory to empirically effective antibiotic treatment. Although the nature of this tumor is highly fatal, the malignancy can possibly be cured by early and aggressive surgical treatment.
