{Abstract}: Tumors of the ovarian epithelial type of testis are an infrequent entity. We report a case of borderline serous tumor in an 18-year-old male who presented with a right testicular mass, clinically suspicious of carcinoma. After right inguinal exploration, two pedunculated para-testicular masses were identified in the appendix of the right testis and epididymis. The histological features were as complex papillary structures lined by columnar cells with mild to moderate pleomorphism. Microscopically, features of borderline serous testicular tumors are identical to the morphology of the same tumors encountered in the ovarian counterparts. These tumors usually reveal papillae with fibrovascular cores lined by stratified cuboidal to columnar epithelium. This case highlights a need for clinicians and pathologists to be aware of this infrequent entity and improve the best patient management attitude. Serous epithelial tumors are common ovary tumors but are very rare entities in the testis. These tumors originate from the remnant of Mullerian ducts or Mullerian metaplasia of tunica vaginalis and are nonaggressive, even associated with extra ovarian spread, and have outstanding prognosis. A review of the literature has shown nearly fifty reported cases worldwide, and most of the cases occur in young to middle-aged adults.
