Fatal hemothorax caused by pseudomesotheliomatous carcinoma of the lung

Pseudomesotheliomatous Primary Squamous Cell Lung Carcinoma: The First Case Reported in Turkey and a Review of the Literature

In rare cases, pseudomesotheliomatous tumors spread diffusely within the pleura to form an encasing mass, which may be confused with diffuse malignant mesothelioma (DMM). A 73-year-old male presented with chest pain, dyspnea and a significant loss of weight and appetite. His radiological and clinical features suggested DMM. However, immunohistochemical studies revealed a primary squamous cell cancer of the lung. To the best of our knowledge, this is the first case report of pseudomesotheliomatous primary squamous cell lung cancer in Turkey, and also the seventh case worldwide. The present report aims to present this case, along with a review of the medical literature.

Local recurrence of lung adenocarcinoma 10 years after left upper lobectomy resembling pseudomesotheliomatous adenocarcinoma: a case report

The form and timing of the local recurrence of lung cancer can be unpredictable and unexpected. Pseudomesotheliomatous adenocarcinoma is a rare tumor that mimics malignant pleural mesothelioma both clinically and pathologically. Distinguishing pseudomesotheliomatous adenocarcinoma from malignant pleural mesothelioma on the basis of clinical findings can be difficult; therefore, a biopsy is usually required for diagnosis. Here we report on a 73-year-old Japanese man who presented with extensive dissemination along the pleural surfaces and clinical findings similar to those of pseudomesotheliomatous lung cancer 10 years after undergoing left upper lobectomy for lung adenocarcinoma. This report provides information that will help physicians establish an accurate diagnosis in similar cases.
