Diagnostic method for malignant pleural effusion distinguishing malignant mesothelioma from lung cancer using pleural carcinoembryonic antigen and hyaluronic acid levels
Malignant mesothelioma (MM) is difficult to diagnose because of the lack of parenchymal opacities, often revealing minimal or absent pleural thickening. Furthermore, pleural effusion has diverse differential diagnoses, including malignancies, infections, as well as collagen vascular and other benign diseases.
Pulmonary sarcomatoid carcinoma mimicking pleural mesothelioma. A case report
Pulmonary sarcomatoid carcinoma (PSC) is an extremely rare biphasic tumor characterized by a mixture of malignant epithelial and mesenchymal cells. Owing to the rarity, as well as the lack of typical manifestations and imaging signs, the rate of misdiagnosis is high. Herein, we present a case of PSC misdiagnosed as pleural mesothelioma in a 59-year-old man.
Localized Mesothelioma of the Pleura: Report of 2 Cases, From Benign to Malignant
Localized mesotheliomas of the pleura are rare, and form a spectrum of low-grade noninvasive indolent lesions that are presumably benign, to more aggressive invasive cancers that, although fully malignant, have a relatively better prognosis than the diffuse type of mesothelioma.
Dysdiadochokinesia, Ataxia, and Anemia: A Sign of Intraluminal Malignant Mesothelioma?
An 87-year-old man presented with altered mental status and ataxia was found to have a neuron-restricted antibody in his cerebrospinal fluid, concerning for a paraneoplastic syndrome of unknown origin. He also exhibited anemia, but otherwise normal electrolytes and liver chemistries.
Gender Differences in Outcomes of Patients With Mesothelioma
Mesothelioma is a rare and deadly form of cancer, linked to asbestos exposure.
