PERICARDIUM, BIOPSY: | |||
- ACUTE AND CHRONIC PERICARDITIS WITH SIDEROPHAGES AND REACTIVE MESOTHELIAL CHANGES. | |||
- NO MICRO-ORGANISMS SEEN WITH ROUTINE STAINING. | |||
- NO EVIDENCE OF MALIGNANCY. | |||
</pre> | |||
====Micro==== | |||
The sections show fibrous tissue with minimal adipose tissue that is covered by mesothelium. A mixed inflammatory infiltrate is present that consists primarily of lymphocytes and plasma cells. Rare eosinophils are seen. Focally, neutrophils are seen and associated with reactive mesothelial cells. Abundant hemosideratin-laden macrophages are seen. No fibrinous strands are seen. No significant nuclear atypia is identified and no atypical infiltrative cell population is identified. No micro-organisms are identified with routine staining. | |||
