title: Rare and unusual metastases of a gastrointestinal stromal tumour.
abstract: Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal tumours of the gastrointestinal tract, histological and immunohistochemistry findings help to differentiate such tumours from other gastrointestinal malignancies. Metastasis is common to the stomach and small bowel and often presents with gastrointestinal bleeding. This is a case of an 82 year old man with an inguinal mass that following exploratory examination was found on histology to be a GIST metastases, imaging also showed pulmonary metastases. Following colonoscopy the primary caecal mass was found. Such metastatic presentations are extremely rare for this type of tumour. This case report highlights these unusual findings.
