TIS is being adopted into practice in cytology laboratories worldwide. In this system, there are six diagnostic categories: non-diagnostic, negative for malignancy, atypia of undetermined significance, suspicious for malignancy, malignant-primary and malignant-secondary. Malignant-primary category almost always implies malignant mesothelioma and malignant-secondary usually refers to metastasis from carcinoma but also to involvement of serous cavity by haematolymphoid and other malignancies. When evaluating effusion cytological specimen adequacy, the factors that must be considered are sample volume, cellular content and cellular preservation. In the diagnostic analysis and interpretation, it is helpful to consider systematically all basic cytomorphological components in a sample. The basic components are architecture, cell populations, cell size, cytoplasm, nuclei and background elements. One important requirement for a successful evaluation of an effusion cytological specimen is sufficient clinical and radiological information in a referral. Clinical information may guide ancillary testing. In the present review, we provide a practical and educational approach to reporting serous effusion cytology based on the TIS.</p>","PeriodicalId":55187,"journal":{"name":"Cytopathology","volume":" ","pages":""},"PeriodicalIF":1.2,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142367554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Common metastatic sites include cervical lymph nodes, liver, bone and lung. This is the case of a patient who presented with an incidental posterior mediastinal mass. Because the posterior mediastinum is an unusual location for MTC, MTC was not a consideration and preliminary histopathological testing did not include calcitonin, which would have been diagnostic.

Histologic review of 12 false-negative cytology cases revealed three key explanations; lymphoma was the most common missed diagnosis (33.3%); fibrinous pericarditis obscures neoplastic cells on the pericardial surface; and pericardial involvement can be seen without extension into the pericardial space.</p><p><strong>Conclusion: </strong>This study demonstrated diagnostic superiority of pericardial fluid cytology over biopsy in the evaluation of malignant pericardial effusions.
