Primary peritoneal adenocarcinoma is a rare cause of malignant pleural effusion. This case highlights its presentation with shortness of breath and bilateral pleural effusions in a 72-year-old female.
Area of Science:
- Oncology
- Pulmonology
- Pathology
Background:
- Malignant pleural effusions are commonly linked to breast, lung, gastrointestinal, and ovarian cancers, as well as lymphomas.
- Primary peritoneal adenocarcinoma is an exceptionally rare etiology of malignant pleural effusion.
Observation:
- A 72-year-old female presented with a two-month history of shortness of breath.
- Thoracic computed tomography (CT) revealed bilateral pleural effusion without discernible mass lesions or mediastinal lymphadenopathy.
- Cytologic analysis of pleural fluid identified adenocarcinoma cells, and abdominal/pelvic CT showed omental thickening with ascites.
Findings:
- Histological examination of a peritoneal lesion confirmed adenocarcinoma.
- The patient was diagnosed with primary peritoneal adenocarcinoma manifesting as bilateral pleural effusion.
Implications:
- This case underscores the importance of considering rare diagnoses in the differential for malignant pleural effusion.
- Early recognition and diagnosis of primary peritoneal adenocarcinoma are crucial for appropriate patient management.
- Further research into the pathogenesis and treatment of primary peritoneal adenocarcinoma may improve patient outcomes.

Pleural Effusion II: Symptoms and Management
A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
