|January 1, 1986
Summary
This study details two cases of low-grade extraovarian pelvic serous tumors, characterized by numerous psammoma bodies. These peritoneal serous carcinomas extensively infiltrated lymphatic vessels, with one patient remaining well eight years post-surgery.
Area of Science:
- Gynecologic Oncology
- Pathology
Background:
- Serous carcinomas can originate from the peritoneum, presenting as extraovarian pelvic masses.
- Psammoma bodies are a common finding in certain types of ovarian and peritoneal neoplasms.
Observation:
- Two cases of low-grade extraovarian pelvic serous tumors were identified.
- Both tumors exhibited a significant presence of psammoma bodies.
- Extensive permeation of myometrial lymphatic vessels by tumor was observed in both instances.
Findings:
- The reported tumors represent a subset of peritoneal serous carcinomas.
- The histological pattern included low-grade serous histology with abundant psammoma bodies.
- Lymphatic vessel invasion into the myometrium was a notable feature.
Implications:
- These findings contribute to understanding the behavior and presentation of rare peritoneal serous tumors.
- The extensive lymphatic permeation highlights a potential route for tumor spread.
- Long-term follow-up, as demonstrated by one patient's outcome, is crucial for assessing prognosis.
