BACKGROUND Pancreatic cancer presents a challenge with its low early diagnosis and treatment rates,leading to high metastasis and mortality rates.The median survival time for advanced pancreatic cancer is a mere 3 months.However,there's hope:small pancreatic cancers diagnosed at an early stage(T1)or those less than or equal to 1 cm in diameter boast an impressive 5-year survival rate of nearly 100%.This underscores the critical importance of early pancreatic cancer detection for significantly improving prognosis.CASE SUMMARY Pancreatic cancer,a malignant tumor of the digestive tract,poses challenges in both diagnosis and treatment due to its occult and atypical clinical symptoms.Clinically,patients with recurrent pancreatitis should be vigilant,as it may be indicative of pancreatic cancer,particularly in middle-aged and elderly patients.Here,we presented the case of a patient who experienced recurrent acute pancreatitis within a span of 2 months.During the initial episode of pancreatitis,routine imaging failed to identify the cause of pancreatic cancer.However,upon recurrence of acute pancreatitis,endoscopic ultrasonography(EUS)revealed a space-occupying lesion approximately 1 cm in size in the pancreatic body.Subsequent EUS coupled with fine-needle aspiration examination demonstrated atypical pancreatic gland epithelium.Ultimately,the patient underwent surgery and was diagnosed with an intraductal papillary mucinous tumor of the pancreas(severe epithelial dysplasia,focal cancer).CONCLUSION We recommend EUS for patients with recurrent pancreatitis of unknown etiology to exclude early pancreatic cancer.
