Abstract
We present a case report of a pulmonary pleomorphic carcinoma that metastasized to the jejunum in an 80-year-old woman. The patient was admitted to the hospital with symptomatic anemia and melena that had been ongoing for several months. In 2021, non-small cell carcinoma was diagnosed by fine-needle aspiration. In 2022, a computed tomography (CT) scan revealed an enormous mass in the small bowel. The tumor was resected and showed pleomorphic neoplastic cells with giant and spindle cell morphology. These neoplastic cells were positive for thyroid transcription factor 1 (TTF1). Next-generation sequencing of the secondary tumor revealed 97% genomic similarities to the lung tumor and high expression of programmed cell death ligand 1 (PD-L1). The patient may benefit from immune checkpoint therapy.
期刊介绍：
The International Journal of Clinical and Experimental Pathology (IJCEP, ISSN 1936-2625) is a peer reviewed, open access online journal. It was founded in 2008 by an international group of academic pathologists and scientists who are devoted to the scientific exploration of human disease and the rapid dissemination of original data. Unlike most other open access online journals, IJCEP will keep all the traditional features of paper print that we are all familiar with, such as continuous volume and issue numbers, as well as continuous page numbers to keep our warm feelings towards an academic journal.
