Next gene sequencing detected TP53 c.919+3del splice site variant and KRAS N116H. It is important to consider HMs when extramediastinal lesions or thrombocytopenia appear in patients with MGCT.

Based on these findings, we concluded that the tumor primarily originated from the prostate and then extended into the left ductus deferens. This case highlights a rare presentation of mixed GCT with unusual anatomical distribution in KS.

The two cases highlight the importance of integrating clinical, imaging, hormonal, and genetic data for diagnosing CAIS with GCTs. WES effectively identified multiple AR mutations, which may contribute to the severe CAIS phenotype and GCT development. Postoperative follow-up (12-24 months) showed no tumor recurrence, and hormone replacement therapy maintained normal secondary sexual characteristics. These findings improve understanding of rare CAIS-GCT comorbidity and support optimized diagnostic and management strategies.

IHC and molecular analyses are crucial for an accurate diagnosis, particularly in tumors with heterologous elements that may mimic other sarcomas or germ cell tumors. Early recognition and multidisciplinary management optimize local control and surveillance planning.

This case shows that monitoring of etoposide plasma concentrations can be beneficial in complex clinical scenarios involving organ dysfunction and/or potential drug-drug interactions. This is especially important in curative treatment to avoid under dosing. This case report highlights the challenges of dosing etoposide in a patient with cystic fibrosis and liver cirrhosis who is taking multiple drugs that may interact with etoposide. The patient should be monitored closely on how the treatment is tolerated and the dose should be adjusted accordingly.

18F-NOTA-R49 demonstrates high affinity and specificity and excellent tumor-targeting properties. It shows better diagnostic efficacy than 18F-FDG in various malignant tumors, indicating a significant clinical translation potential.

The patient subsequently received 3 cycles of bleomycin, etoposide, and cisplatin (BEP) chemotherapy. This case highlights the importance of diagnostic adaptability, multidisciplinary care, and long-term follow-up in achieving successful outcomes for rare thoracic malignancies. Broader lessons include the value of pragmatic decision-making, judicious use of limited diagnostic tools, and structured follow-up strategies that can guide clinicians facing similar challenges in resource-limited environments.

Conclusion Combining classical tumor markers with simple hematological indices offers an expanded perspective on the tumor biology of testicular cancer. NLR and MPV/PLT may serve as complementary markers for tumor aggressiveness and systemic inflammatory response, potentially improving risk stratification and follow-up strategies.

This case highlights that scrotal lymphoma is rare yet highly aggressive, with clinical presentations frequently confused with common malignancies. Diagnosis relies on biopsy and immunohistochemistry, requiring clinicians to remain vigilant for early detection and intervention.

Alterations associated with the formation of a somatic-type malignancy and/or the development of cisplatin resistance include TP53 mutations or MDM2 gene amplifications as well as epigenetic alterations...Additionally, we will provide guidance on how to examine a testicular tumour specimen histopathologically to reach an accurate diagnosis. Finally, we will outline the importance of the content of a histopathological report for the urologists and oncologists.
