Solid pseudopapillary tumor of the pancreas

Summary
Solid-pseudopapillary tumor, a rare pancreatic neoplasm, typically affects young women. This case highlights a favorable prognosis with radical surgical resection, even with potential for microscopic invasion.
Area of Science:
- Oncology
- Gastroenterology
- Surgical Pathology
Background:
- Solid-pseudopapillary tumor (SPN) is a rare pancreatic neoplasm predominantly affecting young females.
- Characterized by large size at diagnosis and low-grade malignancy, SPN has a tendency for invasive growth or metastasis, though rarely observed.
- Potential links to long-term oral contraceptive use are under investigation.
Observation:
- A 53-year-old female presented with a non-metastasizing solid-pseudopapillary tumor of the pancreatic head.
- The patient underwent radical partial pancreatoduodenectomy (T1bN0M0).
Findings:
- Histopathological examination confirmed the diagnosis of solid-pseudopapillary tumor.
- The patient remains recurrence-free with no signs of metastasis 19 months post-surgery.
- Microscopically invasive tumor growth was suspected, supporting the choice of oncologically curative resection over enucleation.
Implications:
- Radical resection is recommended for solid-pseudopapillary tumors to ensure oncological cure, especially when microscopic invasion is suspected.
- Despite its semimalignant nature, solid-pseudopapillary tumor exhibits a favorable prognosis compared to other pancreatic malignancies.
- This case underscores the importance of complete surgical removal for optimal outcomes in managing this rare pancreatic tumor.
