Abstract
Gastrointestinal stromal tumours (GISTs) are rarely encountered in pleural fluid samples. We report a case of GIST metastatic to pleural fluid almost two decades after the original diagnosis. Careful screening by a cytotechnologist, consideration of the clinical history, and judicious use of immunohistochemical stains facilitated the uncommon diagnosis.
