[Testicular pure teratoma: a case report].
A 46-year-old man visited our hospital, complaining of fever and painful swelling of the right scrotum contents. The symptoms and signs suggested epididymitis, but testicular tumor could not be excluded. Therefore, high inguinal orchiectomy was performed. Macroscopic findings were compatible with the testicular teratoma, containing hair, and epididymitis. Histological findings revealed that the tumor was composed of mature epidermis with skin appendages, cartilage, hair, bone and adipose tissue, and that many leucocytes infiltrated in the epididymis, resulting in the diagnosis of pure mature teratoma with epididymitis. For 6 months after the operation, no evidence of recurrence has been observed. Despite its histologically benign appearance, primary pure teratoma of the testis has a metastatic and recurrent potential. Therefore, primary pure teratoma should be man aged in the same way as other nonseminomatous germ cell tumors.
