A 32-year-old male presents to the clinic with a painless mass in his right testicle, which he noticed a few weeks ago. On examination, the mass is firm, non-tender, and does not transilluminate. An ultrasound of the scrotum confirms the presence of a solid intratesticular mass. The clinical team discusses the most likely diagnosis and potential treatment options.
What is the most common type of testicular tumor?
A. Seminoma
B. Teratoma
C. Lymphoma
D. All of the above
E. None of the above
The Correct Answer is: A. Seminoma
Explanation:
– Seminoma (A): Seminoma is the most common type of testicular tumor, particularly in younger men between the ages of 15 and 35. Seminomas are a type of germ cell tumor that tend to grow slowly and are highly responsive to treatment, including radiation and chemotherapy. They generally have an excellent prognosis if detected early.
Explanation of Incorrect Options:
– Teratoma (B): Teratomas are also germ cell tumors but are less common than seminomas. They can contain multiple types of tissue and can be either benign or malignant. Teratomas are more commonly seen in younger boys and in some adults but are not the most common testicular tumor.
– Lymphoma (C): Lymphoma is the most common testicular tumor in older men (over 60 years), but it is not the most common type overall across all age groups. It typically represents a systemic disease rather than a primary testicular tumor.
– All of the Above (D): While all these options can be types of testicular tumors, only seminoma is the most common, making this option incorrect.
– None of the Above (E): Since seminoma is indeed the most common type of testicular tumor, this option is incorrect.
In summary, seminoma is the most common testicular tumor, particularly in younger males, making it the correct answer to this question.
