Abstract
OBJECTIVES: In the pancreatic lesion cases, surgery is often planned based only on imaging results and without a preoperative histological diagnosis, due to the high risk of malignancy in combination with the difficulty of invasive interventions and limited cytopathological evaluation. In this study, the records of 20 patients who had undergone a pancreatectomy procedure and who were diagnosed with nonneoplastic pancreatic lesions were retrospectively evaluated according to the clinical and histopathological findings. METHODS: A total of 122 cases of patients who underwent a pancreatectomy with suspicious lesions between 2004 and 2016 were retrospectively assessed in detail using the clinical and histopathological findings. RESULTS: Nonneoplastic lesions were observed in 20 (16%) of 122 patients who underwent a pancreatectomy. Histopathological examination revealed 11 cases of chronic pancreatitis, 1 hematoma, 1 instance of hemorrhagic necrosis secondary to trauma, 1 pseudocyst, 1 granulation tissue, 1 retention cyst, 1 bile duct cyst, 1 patient with Castleman disease, and 1 instance of fat necrosis were seen. In 1 patient, no evidence of disease was found. In addition, among the patients with chronic pancreatitis, autoimmune pancreatitis was observed in 1, adenomyoma of the ampulla of Vater was present in 1, and a pseudocyst was found in 1 patient. CONCLUSION: A clinical and histopathological analysis of nonneoplastic lesions found in pancreatectomy patients was performed.
