Abstract

Background: Pleural mesothelioma is a very rare neoplasm; especially the local form. The diagnostics is difficult and the prognosis unfavourable.

Case Report: We presented a case of a man with dyspnoea and cough. His chest radiogram showed hydrothorax on the left side. Neither the examinations of the pleural liquid, nor the CT-guided fine needle biopsy established the diagnosis. CT showed features suggestive of pleural mesothelioma. The diagnosis was confirmed by thoracoscopy. Although no neoplastic cells were found in the thoracoscopic specimen from the supradiaphragmatic tumor, we assumed that to be a case of a diffuse, primarily local form of mesothelioma.

Conclusions: Diagnostics of pleural mesothelioma is very difficult. CT and thoracoscopy seem to be very valuable diagnostic methods. It is worth remembering that pleural mesothelioma can have a local form which may transform into a diffuse one.

In plain English

This article was a case report about one patient. A 57-year-old man was admitted to a department of lung diseases with a tiring dry cough and shortness of breath on effort that had lasted three weeks. He had had tuberculosis in childhood, and the report stated he was not exposed to asbestos in his work. A chest X-ray showed fluid in the left pleural cavity. The drained fluid was bloody, and tests on it found no tuberculosis and no cancer cells. CT showed the fluid and a poorly outlined mass between the pleural layers at the base of the left lung, measuring 85 mm at its largest. Two CT-guided needle biopsies found no cancer cells. Thoracoscopy, an examination inside the chest, allowed small pleural nodules to be diagnosed as mesothelioma of the epitheliocellular type. The sample from the larger tumor showed hyalinised tissue without cancer cells. The authors assumed the large tumor was a primarily localised form of mesothelioma. They concluded that CT and thoracoscopy seem very valuable for diagnosis and that a local form may transform into a diffuse one.

We wrote this plain-English summary from the full article with the help of AI, and a second AI model checked each sentence against the article. It is not the authors' wording; the abstract and the article are their own account.

What the study did and found

• Design: case report (one patient)
• Who was studied: One 57-year-old man with a 3-week history of dry cough and shortness of breath on effort and a childhood history of tuberculosis, treated in Poland (Wejherowo hospital, then the Clinic of Chest Surgery of the Medical University of Gdańsk)
• Exposure: The report states the patient was not exposed to asbestos in his work. No other asbestos exposure is described.
• Main results:
  • Chest CT showed fluid in the left pleural cavity and a poorly delineated, inhomogeneous mass between the pleural layers at the base of the left lung, measuring 85 mm in its largest dimension
  • CT-guided fine needle aspiration biopsy was done twice, and no neoplastic cells were found on cytology
  • Biopsies taken at thoracoscopy, examined by microscopy and immunohistochemistry, allowed the small nodular pleural thickening to be diagnosed as mesothelioma
  • The mesothelioma was of the epitheliocellular type
  • The sample from the larger supradiaphragmatic tumor showed hyalinised tissue with haemorrhage and no neoplastic cells
• The authors' conclusion: The authors concluded that diagnosing pleural mesothelioma is very difficult, that CT and thoracoscopy seem to be very valuable diagnostic methods, and that pleural mesothelioma can have a local form which may transform into a diffuse one.
• Limitations the authors state:
  • The authors acknowledged that the sample from the large supradiaphragmatic tumor contained no neoplastic cells, so their view that it was a primarily localised mesothelioma later hyalinised is an assumption
