A RARE CASE OF UNCLASSIFIED CARCINOMA OF THE LUNG: DIAGNOSTIC CHALLENGES

Abstract

The article provides information about a case of pseudomesotheliomatous lung carcinoma, which was clinically undiagnosed but confirmed postmortem through immunohistochemical analysis during differential diagnosis. In the reported case, the diagnosis making was a challenge to physicians, and, therefore, this case deserves attention from surgeons, oncologists and pathologists. Pseudomesotheliomatous carcinoma of the lung is a rare malignant lung tumor, but it should always be kept in mind until the final diagnosis is made in the differential diagnosis of pulmonary disease involving the pleura, especially in the presence of pleural effusion. Nonetheless the poor prognosis and lack of effective treatment approaches, the study of this tumor will further improve the survival of patients and improve the differential diagnosis, since the diagnosis depends mainly on its immunohistochemical verification.
