Metastatic squamous cell cancer of the lung presenting as a perforated cecal cancer

Abstract

Lung cancer is the leading cause of cancer deaths worldwide, with non-small cell lung cancer (NSCLC) accounting for 85% of diagnoses. Metastasis occurs in ~50% of cases but clinically evident isolated gastrointestinal (GI) metastasis is rare. We present a 78-year-old female who underwent an urgent right hemi-colectomy after cross-sectional imaging revealed a perforated cecal mass. Final pathology demonstrated squamous cell cancer of lung origin. We review the literature on NSCLC with clinically evident metastases to the GI tract, as well as important diagnostic considerations.
