In plain English

This was a case report from the University of Hong Kong about one patient, a 32-year-old Chinese woman whose chest X-ray seemed to show an enlarged heart. She had had ankle and wrist joint pains for seven to eight months and had worked for six years in a factory making light bulbs. The report did not describe any asbestos exposure. She had marked clubbing of the fingers and toes and new bone growth in the lower leg bones. Heart tests were normal. Scans showed a large mass in the lower left chest, separate from the heart. Surgeons removed a tumor measuring 19 by 12 by 10 cm and weighing 1.3 kg. Under the microscope it was a fibrous tumor with very few dividing cells, and it was diagnosed as localized fibrous mesothelioma of the pleura. Her recovery after surgery was uneventful, and the authors considered the surgery curative. Citing earlier publications, the authors wrote that, unlike diffuse mesotheliomas, localized mesotheliomas have not been shown to be associated with asbestos exposure.

What the study did and found

• Design: case report (single patient)
• Who was studied: One 32-year-old Chinese woman treated at University of Hong Kong hospitals (Queen Mary Hospital and Grantham Hospital), Hong Kong; date of admission not stated
• Exposure: No asbestos exposure was reported for this patient. The only work history given was six years in a factory manufacturing light bulbs.
• Main results:
  • In the patient, the echocardiogram showed normal-sized heart chambers and normal heart function, with no fluid around the heart.
  • In the patient, the CT scan showed a large mass in the lower half of the left chest, clearly separate from the heart.
  • The patient had marked clubbing of the fingers and toes.
  • The patient had new bone formation under the outer lining of the tibia and fibula (lower leg bones).
  • The tumor removed from the patient measured 19 by 12 by 10 cm and weighed 1.3 kg.
  • Under the microscope, the patient's tumor consisted of fibroblastic spindle cells, with only very occasional dividing (mitotic) cells.
  • The patient's diagnosis was localized fibrous mesothelioma of the pleura.
  • The patient did not have low blood sugar (fasting blood glucose 4.2 mmol/L).
  • The patient's recovery after surgery was uneventful.
  • Background statement drawn from earlier publications, not a finding of this case: the authors wrote that localized mesotheliomas, unlike diffuse mesotheliomas, have not been shown to be associated with asbestos exposure.
• The authors' conclusion: The authors considered the surgery curative because the tumor was completely removed and its capsule was intact. They described the case as unusual because it first appeared on X-ray as an apparently enlarged heart.
