Well-differentiated papillary mesothelioma, abbreviated WDPM, is a rare type of mesothelioma that typically has an indolent behaviour.[1]
It is also known as benign papillary mesothelioma. It should not be confused with malignant mesothelioma or benign multicystic mesothelioma.
General
- Benign.
- Some say it is borderline.[2]
- Classically women of reproductive age.[3]
- Reported in tunica vaginalis of the testis.[4]
- Associated with asbestos exposure.[5]
Gross
Features - typical:
- Multiple peritoneal nodules.
- Ascites.
DDx:[3]
- Tuberculosis.
- Carcinomatosis.
- Primary peritoneal serous carcinoma.
Microscopic
Features:
- Papillary structures with:
- Thick fibrous cores.
- Simple cuboidal epithelium.
- Small nucleoli.
Note:
- Lack cytologic atypia.
