Solid pseudopapillary neoplasm of the pancreas: A case report with a brief literature review

Introduction: Solid pseudopapillary neoplasm (SPN) of the pancreas, representing only 1 % of pancreatic cancers, was identified by Virginia Frantz in 1959. Predominantly affecting young females, it often remains asymptomatic, posing diagnostic challenges due to slow growth. This paper emphasizes SPN's rarity and associated diagnostic complexities. Case presentation: In a specific case, a 17-year-old female with post-traumatic right flank pain underwent an enhanced CT scan, revealing a well-defined, hypodense mass in the pancreatic head. With normal laboratory results, a diagnostic laparotomy exposed a sizable solid cystic mass. A Whipple procedure unveiled a predominantly cystic mass enveloped by a well-developed capsule. Discussion: SPN appears as a distinct mixed solid and cystic lesion on imaging, necessitating confirmation through core biopsy. Surgical resection, the primary treatment, ensures a positive overall prognosis, despite rare recurrence and metastases. Microscopic examination reveals pseudopapillae, and immunohistochemistry aids diagnosis with positive staining for estrogen receptor, progesterone receptor, CD10, and CD99. Conclusion: SPN, a rare pancreatic neoplasm predominantly affecting young females, may present with abdominal pain or palpable mass despite its usual asymptomatic nature. Diagnosis involves imaging and biopsy confirmation, with surgical resection as the curative treatment. While prognosis is generally favorable, comprehensive understanding and improved management require further research for this uncommon pancreatic neoplasm.
