Summary
Solid pseudopapillary tumor of pancreas (SPTP) is a rare exocrine pancreatic tumor primarily affecting young women. Surgical resection offers a cure with an excellent prognosis for this low-malignancy tumor.
Area of Science:
- Oncology
- Gastroenterology
- Pathology
Background:
- Solid pseudopapillary tumor of pancreas (SPTP) is a rare neoplasm of the exocrine pancreas.
- SPTP predominantly affects young women, presenting unique diagnostic and management challenges.
Observation:
- A retrospective review of five SPTP cases (1994-present) included four women (16-47 years) and one man (43 years).
- Clinical presentations varied, including abdominal pain, abdominal distension, and incidental findings.
- Diagnostic imaging (ultrasound, CT) and palpation revealed palpable pancreatic tumors.
Findings:
- Histopathological examination confirmed SPTP in four cases and SPTP carcinoma in one.
- Immunophenotype analysis showed typical tumor cell characteristics, with progesterone receptor positivity in four patients.
- The male patient exhibited negative progesterone and estrogen receptor expression.
Implications:
- SPTP is characterized by low malignancy potential and an excellent prognosis.
- Accurate diagnosis and complete surgical resection are crucial for achieving a cure in most patients.
- Understanding receptor status may inform future therapeutic strategies for SPTP.
