A Case of Metastatic Seminoma Mimicking a Primary Pancreatic Tumor.

Metastatic seminoma to the pancreas is exceedingly rare, with few reported cases in medical literature. We present a case of a 66-year-old male, six years post-remission from testicular seminoma, who presented with obstructive jaundice and a pancreatic mass mimicking primary malignancy. Diagnostic workup including endoscopic ultrasound-guided biopsy confirmed metastatic seminoma. He underwent successful treatment with four cycles of cisplatin and etoposide, achieving complete remission. This case underscores the diagnostic challenge of pancreatic metastases and emphasizes the role of biopsy in guiding appropriate management. Awareness of such presentations is crucial for timely intervention and improved patient outcomes.
