Abstract
In this paper, we describe the case of successful surgical treatment of a rare combination of three malignant tumors of the major duodenal papilla in one patient. A 59-year-old woman presented with abdominal pain, fever, nausea, vomiting, weight loss and obstructive jaundice. After routine examination, the patient with suspected cancer of the major duodenal papilla underwent pylorus-sparing pancreatoduodenal resection. Final histology revealed a rare collision of three types of cancer in the major duodenal papilla invading the pancreatic head: moderately-differentiated adenocarcinoma (30 %), moderately differentiated squamous cell carcinoma (20 %) and poorly differentiated small cell neuroendocrine cancer (50 %), surgical resection margins were intact. Immunohistochemical analysis revealed positivity for synaptophysin, chromogranin A and cytokeratin 5/6. The tumor diameter of 2 cm and the absence of signs of locoregional spread allowed the process to be staged as T2N0M0, so the patient did not receive any adjuvant treatment. Follow-up CT performed 6 months later showed two lesions in the liver, and biopsy of one of them was performed. Metastasis of neuroendocrine cancer was histologically and immunohistochemically verified. She started first-line chemotherapy with etoposide + cisplatin.
