Diagnosis With Brief Discussion

Diagnosis
Desmoplastic Mesothelioma, Pericardium
Radiologic Findings
Chest radiograph shows bilateral pleural effusion with normal sized heart.
Contrast-enhanced CT scans show pericardial irrgular nodular thickening with enhancement and pericardial effusion.
Diagnosis of malignant desmoplastic mesothelioma was made after pericardiectomy.
Gross specimens are several fragments of thickened pericardium with whitish multinodular appearance.
H & E stain: Desmoplastic mesothelioma is characterized by dense collagenized tissue separated by atypical cells arraged in a storiform or patternless pattern.
Immunohistochemistry: positive for cytokeratin(epithelial marker), vimentin(spindle cell marker), D2-40 staining.
Brief Review
1) Pericaldial mesothelioma is a malignant primary neoplasm that arises from the mesothelial cells of the pericardium. The term is used to describe those tumors localized to the pericardium and does not apply to primary pleural tumors that secondarily invade the pericardium. Although pericardial mesotheliomas represent less than 1% of all malignant mesotheliomas, they account for 50% of all primary pericardial tumors.
Malignant pericardial mesothelioma encases the heart and resemble secondary involvement of the pericardium by metastatic malignancy, which is much more common. The most common malignancies that metastasize to the heart are carcinomas of the lung and breast, followed by lymphoma and leukemia.
2) Pathologic features
Malignant pericardial mesotheliomas typically form multiple coalescing pericardial masses that obliterate the pericardial space and constrict the heart. Cut sections of the masses are firm, white, and homogeneous.
3) Radiologic features
Chest radiography typically demonstrates cardiac enlargement, evidence of pericardial effusion, and irregular cardiac contour, or diffuse mediastinal enlargement. Chest CT demonstrates irregular, diffuse pericardial thickening and pericardial effusion. MR imaging also readily demonstrates cardiac encasement by a soft-tissue pericardial mass, as well as an associated pericardial effusion.
