Abstract:
Mesothelioma is a locally aggressive malignant tumor that arises on the mesothelial surfaces of the pleura, peritoneum and tunica vaginalis. There are three histologic subtypes of mesothelioma: epithelioid, biphasic, and sarcomatoid. Pleural mesothelioma is usually characterized by diffuse pleural thickening. Disease progression is characterized by local invasion of the chest wall and lung. Lymphatic metastasis is rare and hematogenous metastasis is much rarer. The purpose of these case reports is to emphasize that pleural mesothelioma metastases can occur in unexpected places and to contribute to the literature.
Insights
Mesothelioma, a rare cancer, typically spreads locally. These case reports highlight that pleural mesothelioma can metastasize to unusual sites, expanding understanding of its progression.
Area of Science:
- Oncology
- Pathology
Background:
- Mesothelioma is a locally aggressive malignancy originating from mesothelial surfaces.
- Histologic subtypes include epithelioid, biphasic, and sarcomatoid.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
