Summary
Solid-pseudopapillary carcinoma (SPC) is a rare pancreatic tumor. Capsular invasion at the surgical margin may indicate malignant potential, necessitating close clinical follow-up.
Area of Science:
- Oncology
- Pathology
- Gastroenterology
Background:
- Solid-pseudopapillary carcinoma (SPC) is a rare, low-grade malignant tumor of the pancreas, predominantly affecting young women.
- This case highlights the diagnostic challenges and clinical course of SPC, initially misdiagnosed as a non-functioning islet cell tumor.
Observation:
- A 34-year-old Japanese woman presented with a 10 cm pancreatic mass, initially diagnosed as a non-functioning islet cell tumor.
- One year and five months post-resection, liver metastasis was confirmed, leading to patient demise shortly after treatment.
Findings:
- Retrospective analysis confirmed SPC based on characteristic solid and pseudopapillary structures and immunohistochemical findings.
- Capsular invasion, particularly at the peritoneal surgical margin, emerged as a key pathological indicator of malignant potential in this SPC case.
Implications:
- The presence of capsular invasion in surgical specimens of solid-pseudopapillary tumors warrants heightened clinical suspicion for malignancy.
- Intensive patient follow-up is crucial for early detection of metastasis and improved management of potentially malignant pancreatic tumors.
