Abstract
BACKGROUND

Squamous cell carcinoma (SCC) in pancreas and stomach is a rare histologic subtype with aggressive behavior, poor prognosis, and no standardized therapy. Pancreatic SCC or gastric SCC has been previously reported. However, case of SCC occurring in both the pancreas and the stomach has not been reported yet.

CASE SUMMARY

A 75-year-old female with prior history of hypertension and diabetes mellitus visited our hospital with complaint of abdominal pain that started three months ago. Computed tomography (CT) scan of the abdomen showed 3.3 cm mass at the distal pancreas. She received surgical resection which was histologically found to be SCC of the pancreas with clear resection margins. After she was discharged, she no longer visited the hospital. Three years later, she was referred to our hospital after showing abnormal findings on a gastroscopy performed at another hospital. Gastroscopy revealed a single, 2cm sized, ill-defined irregular flat and hyperemic mass at high body. Histologic finding of the mass was SCC. CT scan and positive emission tomography CT showed metastatic lesions to the liver and the peritoneum. She received combination chemotherapy with capecitabine and oxaliplatin. However, she passed away 6 mo after diagnosis of gastric SCC.

CONCLUSION

To the best of our knowledge, this is the first case of metachronous SCC of stomach occurring after diagnosis of pancreatic SCC.

Core Tip: Pancreatic squamous cell carcinoma (SCC) and gastric SCC are very rare malignancies with aggressive behavior, poor prognosis, and no standardized therapy. To the best of our knowledge, this is the first case report of metachronous gastric SCC occurring at three years after curative resection of pancreatic cancer.
