Benign peritoneal mesothelioma. Histopathology in a case
Morphologie Et Embryologie
|January 1, 1982
Abstract:
A case of peritoneal mesothelioma was histopathologically diagnosed in a 40-year-old woman. Localized solitary firm nodules found in omentum appeared microscopically as trabecular proliferations with a plexiform pattern in a myxoid stroma. The tumors were penetrated by clefts and cystic cavities lined by a cuboidal or endotheliform epithelium. Rare psammoma bodies were present. The stroma was rich in hyaluronic acid and slightly positive for neutral mucopolysaccharides.
Insights
A rare case of peritoneal mesothelioma was diagnosed in a 40-year-old woman. The omental tumors showed unique microscopic features, including trabecular patterns and cystic cavities.
Area of Science:
- Oncology
- Pathology
- Gastroenterology
Background:
- Peritoneal mesothelioma is a rare malignancy arising from the peritoneum.
- This case presents a unique presentation of localized peritoneal mesothelioma in the omentum.
Observation:
- A 40-year-old woman presented with localized solitary firm nodules in the omentum.
- Microscopic examination revealed trabecular proliferations with a plexiform pattern within a myxoid stroma.
Findings:
- Tumors were characterized by clefts and cystic cavities lined by cuboidal or endotheliform epithelium.
- Rare psammoma bodies were observed.
- The stroma was rich in hyaluronic acid and showed mild positivity for neutral mucopolysaccharides.
Implications:
- This case contributes to the understanding of peritoneal mesothelioma morphology.
- Highlights the importance of histopathological diagnosis for rare peritoneal tumors.
- May inform differential diagnosis in cases of omental masses.
