Epidermoid Cyst is a very rare benign neoplasm of the testis which represents about 1% of all testicular tumors. Ultrasonography findings of epidermoid cyst are so variable in reported cases that it is not eas y to diagnose preoperatively. The echogenecity of mixed echoic. it may show hyperechoic rim, and rarely shows target apperance. Target appearance may be a specific finding of epidermoid cyst, and it may be helpful to diagnose preoperatively. we describe a case of epidermoid cyst of the testis demonstrating double target sign on ultrasonography.

Benign tumors of the testis are rare, accounting for less than one percent of all testicular tumors including epidermoid cyst of the testis. Over hundreds cases have been reported in the world literature but rarely reported cases of the epidermoid cyst with calcified rim and osteogenesis. We report one case of epidermoid cyst incidentally found in plain pelvis A-P film.

Benign tumors of the testis are rare, accounting for one percent of all testicular tumors including epidermoid cyst of the testis. Herein we report one case of epidermoid cyst of the testis and discuss the pathological criteria for diagnosis and clinical management of the lesion.

It’s very important to identify pathological anatomic features in the treatment and prognosis of testicular cancer. In this study, 112 patients who were diagnosed by clinical and paraclinical symptoms were classified according to age, location, and severity. Their samples then were stained by PSA test. Results: 49% were germ cell tumors of scrotum, 9% were none germ cell tumors, and 42% were dystopic germ cell tumors. Base on pathological anatomic features (stage, location) we can apply different methods of treatment to gain better outcomes

Researches on the testicular dysgenesis syndrome (TDS) have flourished in the recent decade, and a widely accepted view on its pathogenesis is that environmental endocrine disrupting chemicals (EDCs) act on Leydig cells and/or testicular Sertoli cells, resulting in abnormal development of the testis and leading to the symptoms of TDS. Molecular biological studies suggest a correlation of TDS etiology with insulin-like factor 3 (INSL-3), androgen receptor (AR), P27kip, WT-1 and Müllerian inhibiting substance (MIS). This review focuses on the progress in current researches on the etiology and mechanism of TDS.

PURPOSE: The object of our study was to examine the clinical significance of pediatric testicular microlithiasis (TM) as it relates to testicular cancer. MATERIALS AND METHODS: Seven boys in whom TM was incidentally detected were followed for a mean of 51+/-44 months (range: 9-119 months) for testicular cancer surveillance. The average patient age at the initial diagnosis was 9.8+/-2.5 years. The frequency of coincidental TM detected on scrotal ultrasonography performed for all clinical purposes at our institution between January 1997 and January 2008 was investigated. Eighty-two testicular cancer patients and 1,006 noncancer patients underwent ultrasonography between 1997 and 2006, and these patients were divided into two age groups (children, age <15 years; adults, age > or =15 years) for purposes of analysis. RESULTS: Of the seven patients followed solely for TM, none developed testicular cancer during the surveillance period. Coincidental TM seen on scrotal ultrasonography was significantly higher in the testicular cancer patients than in the noncancer controls (11% (9/82) vs. 3.5% (36/1,006), p <0.0001). According to the age groups, TM was found in 6% and 5.8% of the testicular cancer patients and the noncancer controls, respectively, in the children's group, whereas in the adult group, 11.6% and 3.3% of the patients in the respective groups were found to have TM. CONCLUSIONS: The incidence of testicular cancer development in children with incidentally detected TM was very low, and the incidence of coincidental TM in children with testicular cancer did not differ from that in the noncancer control patients. However, the significantly higher incidence of TM accompanying testicular cancer after puberty may suggest an association of the two pathologies, which would then mandate cancer surveillance in cases of incidentally detected TM in this age group.

PURPOSE: Testicular microlithiasis (TM) is an uncommon pathologic condition that is commonly diagnosed by scrotal ultrasonography. Indirect evidence suggests that this syndrome may be associated with an increased risk of testicular malignancy and infertility. MATERIALS AND METHODS: A total of 1,439 patients undergoing scrotal ultrasound during a 6-year, 5-month period (January 2003 to May 2009) were retrospectively reviewed. Any possible association of TM with pathologic findings was assessed. Among patients with TM, further grading of TM with testicular cancer and semen analysis of the infertile group with TM were also performed. RESULTS: TM was diagnosed in 87 patients (6.0%) out of a total of 1,439. Of all established pathologic entities, only testicular malignancy and infertility were meaningfully associated with TM. There was no significant difference in the prevalence of testicular cancer between each grade. Seminal profiles (sperm count, motility, morphology, and white blood cell count) were not found to be statistically different between infertile men with and without TM. CONCLUSIONS: The prevalence of TM in symptomatic men was found to be 6.0% with significant co-occurrence of TM, testicular cancer, and infertility. Further grading of TM does not seem to be essential with regard to the detection of patients with testicular cancer and TM. TM showed no significant effect on the seminal profiles of infertile men.
