“…Accurate preoperative diagnosis of pancreatic metastasis rather than a primary pancreatic cancer is difficult [7–10,12]. Cytological examination of a fine needle aspirate or pathological examination of a biopsy specimen obtained under endoscopic ultrasonography guidance is useful for preoperative diagnosis [4,8,9,20,21].…”

“…Optimal treatment for pancreatic metastasis has not yet been established [5,8,10,15,20]. Pancreatic resection may confer a survival benefit on patients with pancreatic metastases [2,5–10,12–15,20], the 5-year survival rate after this procedure reportedly being approximately 30% [23]. Cases of successfully resected pancreatic metastases from colorectal cancer after multiple resections of metastatic lesions have been reported [2,5–10,12–14,24].…”

“…Pancreatic metastases from colorectal cancer are rare [3–14], and acceptable outcomes can be achieved by curative resection in carefully selected patients [5,6,8,10,12–15]. Treatment guidelines recommend aggressive resection of hematogenous metastases (i.e., lung or liver metastases) [16,17] if radiographic and/or surgical R0 (i.e., radiographic/surgical R0 resection, according to the Japanese Classification of Colorectal, Appendiceal and Anal carcinoma [18]) is accomplished [5,7–10,12,13,15–17]. Whether pancreatic metastases occur via hematogenous pathways is controversial [7–10,12].…”

Patient: Male, 70Final Diagnosis: Metachronous pancreatic metastasisSymptoms: NoneMedication: —Clinical Procedure: SurgerySpecialty: Gastroenterology and HepatologyObjective:Rare diseaseBackground:Pancreatic metastasis from colorectal cancer is rare and can masquerade as primary pancreatic cancer.Case Report:A 70-year-old male was diagnosed with advanced rectal cancer with multiple liver metastases. After neoadjuvant chemotherapy, he underwent radical surgery for the primary tumor and hepatectomy for multiple liver metastases. Adjuvant chemotherapies and additional surgeries were subsequently required for recurrences in the liver, lung, and lymph nodes. A diffuse hypovascular nodule in the pancreatic head and a solitary liver metastasis were detected 2.5 years after the initial surgery and he accordingly underwent further chemotherapy. However, the pancreatic tumor progressed, invading the pancreatic duct and biliary tract. Obstructive jaundice finally prompted discontinuation of chemotherapy and he underwent biliary drainage. His diffuse and hypovascular tumor was clinically and radiographically diagnosed as a primary pancreatic cancer. Pancreatic resection for the pancreatic tumor and hepatectomy for the liver metastasis were performed 4.2 years after the initial surgery, achieving radiographic and surgical curative resection. Pathological examination of the surgical specimen resulted in a definitive diagnosis of metachronous pancreatic metastasis from his primary rectal cancer. Despite further chemotherapy, his general condition worsened; however, he remains alive 5.4 years after the initial surgery, with best supportive care.Conclusions:Pancreatic metastasis originating from rectal cancer can masquerade as primary pancreatic cancer clinically and radiologically. Multimodality treatment is mandatory for metastatic colorectal cancer. Aggressive surgeries for pancreatic metastasis should be considered if curative resection appears possible radiographically and/or intraoperatively.

Rare metastatic pancreatic tumors from lung cancer with cystic changes resembling intraductal papillary mucinous neoplasm: a case report

et al. 2020

Background: Metastatic pancreatic tumors from lung cancer (MPTLC) constitute 3% of all metastatic pancreatic tumors. We present an extremely rare case of cystic MPTLC that was difficult to distinguish from intraductal papillary mucinous neoplasm (IPMN). Case presentation: The patient was a 74-year-old woman who underwent lobectomy of lung cancer 2 years before presentation to our hospital. She was referred to our department for resection of cystic pancreatic tumors, which were diagnosed as IPMN with high-risk stigmata. Abdominal computed tomography (CT) showed a 37-mmwide cystic tumor with a contrasted solid nodule in the pancreatic head and a 17-mm-wide cystic tumor in the pancreatic tail. We performed a total pancreatectomy for these lesions. According to histopathological and immunohistochemical findings, the tumors were diagnosed as metastatic pancreatic tumors from lung cancer. Conclusion: In this case, the cystic morphology was formed by eosinophilic secretions from tumor cells, and it was difficult to distinguish from IPMN with high-risk stigmata. We consider this case, based on the variable clinical findings, an extremely rare variant of MPTLC.

: We present a case of metastatic leiomyosarcoma of the pancreas diagnosed by needle biopsy under computed tomography, and development of obstructive jaundice 8 years after resection of a left tibial leiomyosarcoma. A 58-year-old woman was admitted to our hospital with jaundice.Computed tomography and magnetic resonance image showed a 2.5 cm mass in the head of the pancreas.We obtained a biopsy from the tumor that showed histopathological features identical to those of the leiomyosarcoma in the left tibia resected 8 years ago.The lesion was suspected as metastatic leiomyosarcoma of the pancreas and the patient underwent pylorus-preserving pancreatoduodenectomy.
