Core Tip
Core Tip: Pancreatic schwannoma is a rare benign tumor that often mimics solid pseudopapillary tumor on imaging. This case highlights the diagnostic challenge and emphasizes that complete surgical resection is curative. Definitive diagnosis requires immunohistochemical confirmation with S-100 and SRY-related high-mobility group-box 10 positive positivity.
