Abstract:
Pleural mesothelioma is a rare neoplasm with the incidence of 1-2 per million people. The incidence is higher in male population (10-30/million), whereas the incidence in female population is 2 per million. It occurs predominantly at older age (65+ years). The most common clinical manifestation of pleural mesothelioma is pleural effusion with dyspnea, which makes it a diagnostic problem since many cardiac diseases can have the same presentation. We report a case of pleural mesothelioma in an 80-year-old woman that presented with dyspnea and pleural effusion, which was at first considered as a sign of heart failure. Clinical presentation also included metabolic disorders and deep vein thrombosis, and the patient's epidemiologic history was negative, so diagnostic procedures including pleurocentesis were directed towards detection of the possible malignant disease. Cytologic analysis followed by biopsy pointed to the diagnosis of pleural mesothelioma. Persistent pleural effusions that do not coincide with cardiac disease, especially if accompanied by metabolic disorders and paraneoplastic syndromes, require additional diagnostic workup to identify the etiology of pleural effusion.
Insights
Pleural mesothelioma, a rare cancer, often presents as pleural effusion and dyspnea. This case highlights the need for thorough investigation beyond heart failure, especially with metabolic disorders.
Area of Science:
- Oncology
- Pulmonology
- Pathology
Background:
- Pleural mesothelioma is a rare malignancy with a low incidence, predominantly affecting older males.
- Dyspnea and pleural effusion are common symptoms, often mimicking cardiac conditions, posing diagnostic challenges.
Observation:
- A case study of an 80-year-old woman with dyspnea and pleural effusion initially suspected as heart failure.
- The patient also exhibited metabolic disorders and deep vein thrombosis, with no significant epidemiological history.
- Diagnostic procedures, including pleurocentesis, were initiated to rule out malignancy.
Findings:
- Cytologic analysis and subsequent biopsy confirmed the diagnosis of pleural mesothelioma.
- The case underscores the complexity of diagnosing this rare cancer.
Implications:
- Persistent pleural effusions, particularly when accompanied by metabolic disturbances or paraneoplastic syndromes and not explained by cardiac disease, necessitate comprehensive diagnostic evaluation.
- Early and accurate diagnosis of pleural mesothelioma is crucial for appropriate patient management and treatment planning.

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.
