Abstract:
Malignant mesotheliomas are aggressive neoplasms arising from mesothelial cells lining the body cavities. Malignant peritoneal mesothelioma (MPM) account for about one-third of the cases. Though the ovarian involvement may be seen in the background of a diffuse peritoneal involvement, the presentation of MPM as a primary ovarian mass is rare. Here we present such a case who underwent surgery but had residual progressive lesion. She received further chemotherapy resulting in a complete response and is disease free for almost a year.
Insights
Malignant peritoneal mesothelioma (MPM) rarely presents as a primary ovarian mass. This case study shows successful chemotherapy treatment leading to a complete response and sustained remission.
Area of Science:
- Oncology
- Pathology
- Gynecologic Oncology
Background:
- Malignant mesotheliomas are aggressive neoplasms originating from mesothelial cells.
- Malignant peritoneal mesothelioma (MPM) constitutes approximately one-third of mesothelioma cases.
- Ovarian involvement in MPM typically occurs secondary to diffuse peritoneal disease.
Observation:
- This report details a rare instance of MPM presenting as a primary ovarian mass.
- The patient underwent surgical intervention, which resulted in a residual progressive lesion.
- Subsequent chemotherapy led to a complete response.
Findings:
- The patient achieved a complete response to chemotherapy.
- The patient has remained disease-free for nearly one year post-treatment.
- This case highlights an unusual presentation of MPM.
Implications:
- This case underscores the importance of considering rare presentations of MPM in gynecologic oncology.
- Effective chemotherapy regimens can achieve durable remission in select MPM cases.
- Further research into primary ovarian MPM is warranted to optimize diagnostic and therapeutic strategies.
