The most common type of testicular tumor is the seminoma, which accounts for approximately 40-50% of all testicular germ cell tumors. Seminomas are malignant tumors that arise from the germinal epithelium of the seminiferous tubules. They are characterized by their uniform appearance under the microscope, consisting of large, round cells with clear cytoplasm and prominent nuclei. Clinically, seminomas typically present in men between the ages of 30 and 40 as a painless, firm swelling or enlargement of one testicle. They are highly sensitive to both radiation therapy and chemotherapy, which contributes to their excellent prognosis, especially when diagnosed at an early stage. A key biochemical marker associated with some seminomas is a mildly elevated serum level of human chorionic gonadotropin (hCG), while alpha-fetoprotein (AFP) levels remain normal. It is crucial to differentiate seminomas from non-seminomatous germ cell tumors (like embryonal carcinoma or teratoma), as the treatment strategies and prognoses differ significantly.
