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.

3.300 cycles of sperm retrieval from the epididymis and the testis for the intracytoplasmic sperm injection
Journal of Medical and Pharmaceutical Information 2004;0(7):24-30
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

4.Epididymal Anomalies in Cryptorchidism and Hydrocele : Association with Patent Processus Vaginalis.
Korean Journal of Urology 1999;40(9):1231-1234
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.

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.

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.

Adenomatoid tumor is the common neoplasm of the paratesticular tissue that generally is considered to be of mesothelial derivation. But, there are only few reports on adenomatoid tumor of the epididymis associated with cryptorchid testis in the world. We report an unusual tumor that occurred in epididymis associated with intraperitoneal cryptorchid testis of a 32-year-old man andwas confirmed as an adenomatoid tumor by light microscopy.

A rare case of an epididymal leiomyoma in a 62-year-old man is reported. A physical examination revealed a hard, non-tender, 2cm sized round mass located in the tail of the right epididymis. Scrotal ultrasonography showed a 2.1x2cm sized, well defined round inhomogeneous mass within the tail of the right epididymis. A right epididymectomy was performed. The diagnosis was confirmed by surgical excision and subsequent histological analysis.

OBJECTIVE: To estimate the incidence of falsely elevated risk of ovarian malignancy algorithm (ROMA) in a group of women with pathologically confirmed endometrioma and to investigate the associated factors. METHODS: One hundred premenopausal women surgically diagnosed with ovarian endometrioma were selected. Preoperative clinical, laboratory, and surgical characteristics were compared between the elevated-risk group (ROMA-premenopausal value, ≥7.4%) and normal-risk group (ROMA-premenopausal value, <7.4%). RESULTS: Elevated ROMA was observed in 15 women (false positive rate, 15%). Excluding one woman with known chronic renal failure, we compared the characteristics of 99 women between the elevated-risk group (n=14) and the normalrisk group (n=85). None of the clinical and surgical variables distinguished the two groups. Serum level of CA 125 >82.3 U/mL and serum level of human epididymis protein 4 (HE4) >46 pmol/L could predict an elevated ROMA test with a statistical significance. When serum level of HE4 ≤46 pmol/L, none of the women showed an elevated ROMA test, regardless of serum level of CA 125; however, 55.6% of the women showed an elevated ROMA test when serum level of HE4 >46 pmol/L and CA 125 ≤82.3 U/mL and all women showed an elevated ROMA test when serum level of HE4 >46 pmol/L and CA 125 >82.3 U/mL. CONCLUSION: The incidence of falsely elevated ROMA was 15% in the group of women with pathologically confirmed endometrioma. Interpretation of the ROMA results should be cautious when serum level of HE4 >46 pmol/L and CA 125 >82.3 U/mL in women with suspicious ovarian endometrioma.
