Compound Nevus with Severe Dysplastic Feature in Mixed Germ Cell Tumor: A Case Report

Introduction 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, the 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, the effects of radiation are brighter than chemotherapy. Recent studies reported melanoma and malignant skin changes as secondary malignancies in these people. Case presentation this study tends to introduce a 31-year-old patient with a mixed germ cell tumor and severe dysplastic changes in a compound nevus. Our patient had long-term exposure to sunlight and numerous skin nevi before the diagnosis of testicular cancer. Conclusions  The findings do not certainly support the relationship between the emergence of a nevus with severe dysplastic changes and testicular tumor.
