Which tumor is associated with endocrine imbalance due to hormone production?

• A. Germ Cell Stromal Tumor
• B. Lymphoma
• C. Choriocarcinoma
• D. Leydig Cell Tumor

Answer: (D)

Endocrine imbalance from a tumor comes from the tumor producing hormones. Leydig cell tumors arise from the testicular interstitial Leydig cells, which normally make testosterone. When a Leydig cell tumor is present, it can autonomously secrete androgens, leading to systemic effects like virilization or precocious puberty. That direct hormone production is the classic cause of endocrine changes, making this tumor the best match. The other tumors listed are not primarily defined by hormone production causing systemic endocrine effects.
