Abstract
Primary pulmonary enteric adenocarcinoma (P-PEAC) is an unusual subtype of invasive lung adenocarcinoma. The significance of such tumor lies in its similar histopathological and immunohistochemical characteristics to colorectal adenocarcinoma. Therefore, a detailed investigation is crucial to establish a definitive diagnosis. This paper reports a case of a 51-year-old Saudi female, diagnosed with a rare variant of lung carcinoma, P-PEAC.
