Tumors of the epididymis are rare. The most common one is adenomatoid tumor. At least more than two hundred cases have been reported in the literature but only one was reported by us last year in this country. We add another one which is involving bilateral epididymis simultaneously and review literature briefly.

PURPOSE: To evaluate the US findings of epididymal adenomatoid tumor. MATERIALS AND METHODS: Were trospectively reviewed US findings of four patients with histopathologically proven epididymal adenomatoidtumors. Lesions were evaluated for their size, location, margin, shape and echogenicity. RESULTS: The size of thetumors ranged between 0.5cm and 2cm and all occurred on the left side of the epididymis. Of the four cases, three were located at the tail of the epididymis and one at its head. The tumors were well marginated and spherical andecho-texture was variable but homogenous. CONCLUSION: The possibility of and adenomatoid tumor should be considered when the epididymal mass is round and has a clear margin and the echo-texture of ultrasound ishomogenous.

In this cross-sectional retrospective study, 300 cycles of sperm retrieval from the epididymis and the testis on 213 patients for the intracytoplasmic sperm injection at the Infertility Department of Tu Du Hospital from March 2003 to May 2004 were examined. The results showed that: 100% cycles with embryos and the pregnancy rate of 47.9%; there is no complication except a mild scrotal discomfort lasting a few days after open surgery; percutaneous epididymal sperm aspiration (PESA) was the most performed retrieval technique (61%), which was easy-done, quickly-performed, safe and effective

Monorchism is a congenital anomaly showing complete absence of a testis on one side. We experienced a cases of monorchism in an 11 year-old boy, diagnosed through exploratory laparotomy. We can find the spermatic vessels and was deferens, but not testis and epididymis on the right side. The opposite testis was normal on palpation. Herein, we add another one case of monorchism after the report of 2 cases in 1978.

PURPOSE: Epididymal anomalies in boys with an undescended testis have been well documented and most undescended testes are associated with patent processus vaginalis. However, the incidence of epididymal anomalies in descended testes has not well known. We performed a prospective study to determine the relationship between epididymal anomalies and patency of processus vaginalis in boys with hydrocele or cryptorchidism. MATERIALS AND METHODS: From January 1997 to February 1988, epididymal morphologies and the degrees of patency of processus vaginalis(closed, partially closed and open) were examined in 35 boys with hydrocele(37 testes) and 28 boys with cryptorchidism(29 testes) at the surgeries. RESULTS: No epididymal anomaly was found in all 3 hydroceles with closed processus vaginalis. Epididymal anomalies were found in 13 of 22 hydroceles with partially closed processus vaginalis and in 9 of 12 hydroceles with open processus vaginalis. All boys with undescended testes had open processus vagnialis and the epididymal anomalies were found in 27 of 29 undescended testes. The incidence of epididymal anomalies was highest in cryptorchid testes with open processus vaginalis and lowest in descended testes with closed processus vaginalis. Furthermore, epididymal anomalies were found to be more severe in association with more cranially located testes. CONCLUSIONS: The higher incidence of epididymal anomalies were associated with ipsilateral patency of processus vaginalis and testicular position. This finding suggests that the role of the epididymis in testicular descent may not be essential.

A hemangioma is a benign tumor arising in the vessels, but an intrascrotal hemangioma is rare, and a hemangioma of the epididymis is extremely rare. Ultrasound and MRI (magnetic resonance imaging) are mainly used for the diagnosis of an intrascrotal hemangioma, with surgical excision being the appropriate treatment. We report on the case of a 24 year- old-man with a mixed hemangioma of the epididymis.

The effects of vasectomy on the reproductive organs in various species are controversial. This study investigated the morphological change and apoptosis of the testis, epididymis, and vas deferens in beagle dogs 12 months after vasectomy. The male beagles were divided into two groups: vasectomized and sham-operated groups (n=5 in each). Histopathological, ultrastructural, and TUNEL evaluation of the changes in the testis, epididymis, and ductus deferens of each animal were conducted 12 months after surgery. The mean lumen diameter, cellular thickness, mean interstitial distance, and lumen area fraction of each seminiferous tubule and ductus epididymis were measured by stereological analysis. The results showed that, compared with the sham-operated group, the seminiferous tubular epithelial cells of the testes in the vasectomized group were disorderly arranged and scattered. Significant atrophy and apoptosis were found in the endothelial cells, and a range of ultrastructural variations were observed in the cells of testes, epididymis, and vas deferens in vasectomized group. It was concluded that complete obstruction of the vas deferens as a traditional contraception method is not absolutely safe in terms of the reversal of fertility in the long run. Techniques of relieving the inner pressure in the vas deferens while maintaining the efficacy of male contraception need to be explored.

Adenomatoid tumors are rare benign neoplasms thought to be of mesothelial origin. Although most reported cases developed from the epididymis, rare cases have been reported in the testicular tunica, spermatic cord and ejaculatory ducts. Because of the benign nature of this tumor, the treatment of choice is local excision. We report a rare case of adenomatoid tumor of the spermatic cord treated by local excision.
