Abstract:
We present a case of a male with benign cystic mesothelioma of the peritoneum. The literature is reviewed for previous case reports of this rare lesion in males. Benign cystic mesotheliomas occur predominantly in females. Despite a marked tendency to recur, no malignant degeneration has ever been demonstrated, and only one mortality has ever been attributed directly to this lesion. The diagnosis of this entity is made by confirming the benign mesothelial nature of the cells lining the cysts with electron microscopy or immunohistochemical staining. No significant difference in the clinicopathologic presentation of cystic mesotheliomas in men and women is found.
Insights
This case report details a rare benign cystic mesothelioma in a male patient. While typically seen in females, this lesion shows similar clinical behavior and prognosis in both sexes.
Area of Science:
- Oncology
- Pathology
- Surgical Oncology
Background:
- Benign cystic mesothelioma is a rare peritoneal tumor predominantly affecting females.
- Understanding its occurrence in males is crucial for accurate diagnosis and management.
Observation:
- A case of benign cystic mesothelioma in a male patient is presented.
- Literature review reveals limited reports of this condition in males.
Findings:
- Benign cystic mesothelioma, though prone to recurrence, rarely shows malignant transformation or significant mortality.
- Diagnostic confirmation relies on electron microscopy or immunohistochemical staining to identify benign mesothelial cells.
- Clinicopathologic presentation is similar between male and female patients.
Implications:
- This report expands the understanding of benign cystic mesothelioma in males.
- It underscores the importance of accurate diagnosis to differentiate from malignant peritoneal lesions.
- Clinical management and prognosis appear consistent across sexes despite the rarity in males.
