Abstract
We present a case report of a 76-year-old male with a histologically confirmed KRAS mutated, thyroid transcription factor 1 (TTF1) positive, grade 1, mucinous adenocarcinoma with cytologically difficult to interpret lymph node metastasis showing loss of TTF1 expression and overlapping features with goblet cell hyperplasia. The case highlights the importance of molecular testing in aiding diagnosis and guiding treatment of non-small cell lung carcinomas (NSCLC).
期刊介绍：
Diagnostic Cytopathology is intended to provide a forum for the exchange of information in the field of cytopathology, with special emphasis on the practical, clinical aspects of the discipline. The editors invite original scientific articles, as well as special review articles, feature articles, and letters to the editor, from laboratory professionals engaged in the practice of cytopathology. Manuscripts are accepted for publication on the basis of scientific merit, practical significance, and suitability for publication in a journal dedicated to this discipline. Original articles can be considered only with the understanding that they have never been published before and that they have not been submitted for simultaneous review to another publication.
