Testicular metastases from renal cell carcinoma (RCC) are extremely rare. Tyrosine kinase inhibitors (TKI) are the cornerstone of systemic therapy for metastatic RCC. We report a case of testicular metastasis in a 72-year-old patient with RCC that developed 17 years after nephrectomy and response to TKI treatment, a retrospective literature search on testicular metastases from RCC, and the indirect evidence described in the literature on the efficacy of chemotherapy and target therapy on testicular lesions.

(1) Background: Testicular cancer, although accounting for only 0.5% to 1% of all solid male cancers, is the most common malignancy in males aged 15 to 35 years. Non-seminomatous germ cell tumors (NSGCT) represent nearly half of all testicular germ cell tumors and are associated with a more aggressive clinical course.

A 26-year-old male presented to a hospital with complaints of hemoptysis and right scrotal swelling. Computed tomography (CT) revealed right testicular swelling, multiple lung metastases, and small intestinal wall thickening. The patient's β-human chorionic gonadotropin, alpha-fetoprotein, lactate dehydrogenase, and hemoglobin levels were 103.

Testicular cancer is the most commonly diagnosed cancer among young men in the United States. Seminoma comprises a little over half of all testicular germ cell neoplasms. After radial inguinal orchiectomy, management of seminoma is dictated by tumor stage and risk stratification.

We present a case of a 36-year-old male found to have a nonseminomatous germ cell tumor (NSGCT) with alpha-fetoprotein levels (AFP) of 737.9 ng/mL and beta-human chorionic gonadotropin (β-HCG) of 692 IU/mL. Pathology analysis after left orchiectomy showed a mixed germ cell tumor with 20% embryonal carcinoma, 20% yolk sac tumor, and 60% teratoma.

Predicting the histopathology of residual retroperitoneal masses (RMMs) before post-chemotherapy retroperitoneal lymph node dissection in metastatic nonseminomatous germ cell tumors (NSGCTs) can guide individualized treatment and minimize complications. Previous single approach-based models perform poorly in validation. Herein, we introduce a machine learning model that evolves from a single-dimensional tumor diameter to incorporate high-dimensional radiomic features, with its effectiveness assessed using the macro-average area under the receiver operating characteristic curves (AUCs).
