Background:
Testicular mixed germ cell tumors (TMGCTs) are rare malignant tumors that are more common in men aged 20-40 years. TMGCTs comprise two or more types of germ cell tumors that primarily affect the testis. Their onset is undetectable; thus, early diagnosis is challenging. However, early recognition and diagnosis substantially improve patient prognosis.
Case Summary:
We evaluated a rare case of TMGCT in a male patient presenting with recurrent fever and left supraclavicular lymphadenectasis instead of testicular enlargement and pain, which may easily lead to misdiagnosis. We report the clinical signs and symptoms, histopathological characteristics, and immunohistochemical results of this case of malignant TMGCT.
Conclusion:
Our case, which was typical with multiple components, along with a literature review, may serve as a basis for early diagnosis.
