Cytological Profile of a Case of Malignant Mesothelioma of Pleura with Supraclavicular Lymph Node Metastasis.

Malignant mesothelioma of pleura is a locally aggressive rare neoplasm of mesothelial cells, which produces distant metastasis in advanced stages of its course. It is exceptional for patients to present with metastasis prior to the detection of primary tumor in the pleura. Here, we report a case of malignant mesothelioma of pleura in a 65-year-old quarry worker where the initial diagnosis was offered by fine needle aspiration of an enlarged supraclavicular lymph node. Subsequent pleural fine needle aspiration cytology (FNAC), tumor biopsy, and immunohistochemical analysis confirmed the diagnosis.
