Abstract

Mesothelioma is a rare and aggressive malignancy typically associated with asbestos exposure. We present the clinical and diagnostic journey of a 63-year-old male carpenter, who presented with concerning symptoms of shortness of breath and total right lung "white-out" on imaging. Comprehensive medical evaluation revealed the presence of malignant pleural mesothelioma. This study underscores the importance of considering mesothelioma as a potential diagnosis in individuals with occupational asbestos exposure and highlights patterns in diagnosing and managing this devastating disease. Early recognition and intervention are essential in improving outcomes for patients diagnosed with mesothelioma.

In plain English

Despite its title, this article is a case report about one patient, not a review of many cases. The authors described a 63-year-old man working as a carpenter in the inner city who had three months of worsening shortness of breath, fatigue and a 10-pound weight loss. Imaging showed complete right-sided opacification. A CT scan showed a large right pleural effusion with nodularity of the lung tissue. Fluid drained from his chest was exudative. Pleural biopsies taken during video-assisted thoracoscopic surgery showed low-grade epithelioid mesothelioma, and tissue staining was positive for cytokeratin-5, cytokeratin-7, calretinin and WT-1. The authors identified a potential long-term occupational exposure to asbestos in his history. They gave no fiber type, products or duration. Chemotherapy with cisplatin, pemetrexed and bevacizumab was described as being planned. The authors judged his prognosis positive because of his good health and the low-grade tumor. They concluded that mesothelioma should be considered as a possible diagnosis in people with occupational asbestos exposure. A single case describes one person's illness and gives no rates.

What the study did and found

• Design: Case report (single patient), despite the title calling it a comprehensive review
• Who was studied: One 63-year-old man, originally from Mexico, living in the United States for over 20 years and working as a carpenter in the inner city. He presented to an emergency room of BronxCare Health System, New York City (the authors' affiliation).
• Exposure: Potential long-term occupational asbestos exposure, identified from the history of a carpenter. No fiber type, product, duration or dose is given for the patient.
• Main results:
  • For the patient, CT of the chest showed a large right pleural effusion with nodularity of the lung parenchyma concerning for neoplasm, a possible obstructive endobronchial lesion, and a mediastinal shift to the left.
  • Thoracentesis of the right-sided collection showed an exudative effusion.
  • Pleural biopsies taken during video-assisted thoracoscopic surgery were positive for low-grade epithelioid mesothelioma.
  • Immunohistochemical staining of the biopsy was positive for cytokeratin-5, cytokeratin-7, calretinin and WT-1, with weak staining for BAP1 and MTAP.
  • Oncology was consulted, and chemotherapy with cisplatin, pemetrexed and bevacizumab was being planned.
  • The authors described the tumor as low-grade with no nodal involvement or metastasis, and judged the patient's overall prognosis to be positive.
• The authors' conclusion: The authors concluded that mesothelioma should be considered as a potential diagnosis in people with occupational asbestos exposure, and that timely and accurate diagnosis is crucial.
