Introduction: Metastatic squamous cell carcinomas (SCC), though common, are rarely seen in effusions. According to recent literature, the incidence of metastatic squamous cell carcinoma in body cavity fluids is 0.5 – 2.7%. Hence a misdiagnosis of metastatic SCC is very common. But there are some cytomorphological features which can aid us in the accurate diagnosis. A study of the morphological features was done and the morphological features are described in detail for the diagnosis of metastatic SCC. We aim to study the cytomorphological features of metastatic squamous cell carcinoma in effusion fluids.
Material and methods: All effusion fluid specimens reported as positive for malignancy with squamous component from January 2014 to January 2019 were included in the study. Adequate clinical details were collected from the database.
Results: In the study period, 21 effusion fluid specimens, which included 10 peritoneal and 11 pleural fluids from 16 patients, were reported as squamous cell carcinoma (SCC). 14 of these cases had histopathological correlation and diagnosis. Diagnosis of metastasis was made either based on established morphological features or when a discrepancy was encountered, aid of immunocytochemistry or immunohistochemistry with p63 facilitated in arriving at the diagnosis.
Conclusion: Although rare, SCC can be identified in serous effusions. To prevent misdiagnosis, correlation with clinical history and type of original tumor is necessary, along with increased awareness of the cytomorphological types and IHC overlap between carcinomas. Furthermore, the cytological diagnosis of metastatic SCC will give the patient a dismal prognosis
