Abstract

Testicular cancer is the most common tumor of the genital tract of 18-39 years-old men; its incidence is increasing in recent decades. However, 10-year survival rate of testicular cancer is above 90%, which can result from radiation and chemotherapy used to treat patients. Testicular cancer patients are at risk for secondary malignancies; in this regard, effects of radiation are brighter than chemotherapy. Recent studies reported melanoma and malignant skin changes as secondary malignancies in this people. Therefore, this study tends to introduce a 31 year-old patient with mixed germ cell tumor and severe dysplastic changes in a compound nevus. As our patient had long-term exposure to sunlight and numerous skin nevi before diagnosis of testicular cancer, findings do not certainly support the relationship between emergence of nevus with severe dysplastic changes and testicular tumor.
