Rapidly progressive sarcomatoid malignant mesothelioma of the pleura mimicking pulmonary empyema

Alveolar‐filling growth pattern of sarcomatoid malignant pleural mesothelioma

A case of sarcomatoid malignant pleural mesothelioma showing extremely rare growth pattern is described. A 63-year-old man presented to our hospital with left pleural effusion. A computed tomography (CT) scan of the chest showed diffusely thickened left visceral and parietal pleura associated with intermingled pulmonary infiltrative shadowing. Biopsy of the pleura under general anaesthesia conf...

Squamous-cell carcinoma of the pleura.

There are few reports of primary malignant tumours of the pleura other than mesothelioma. Reports of squamous-cell carcinoma of the pleura are especially rare. Epidermoid carcinoma of the pleura may occur in connection with persistent empyema drained by a pleurocutaneous fistula or long-standing extrapleural pneumothorax without fistula.

A cytokeratin- and calretinin-negative staining sarcomatoid malignant mesothelioma.

Malignant Mesothelioma, or mesothelioma, is a mesothelial-based malignancy that may occur in the pleura, pericardium and peritoneum. Mesothelioma is a very aggressive cancer with limited treatment, and a median survival of about 1 year. At times, the diagnosis of mesothelioma may be problematic. The final diagnosis of mesothelioma relies on histology and often is dependent upon immunohistochemi...

Malignant Desmoplastic Type Mesothelioma Mimicking a Fibrous Pseudo- tumor of the Tunica Vaginalis: A Case Report and Literature Review

Malignant mesothelioma is an uncommon tumor of serosal surfaces. The most common sites of origin include the pleura and the peritoneum. Malignant mesothelioma of the tunica vaginalis testis is rare. We describe a 78 year-old man with a 2-month history of a rapidly enlarging scrotum. The initial pathologic diagnosis was fibrous pseudotumor by the presence of cellular spindle cells and the backgr...
