Gastrointestinal stromal tumours (GISTs) constitute the largest category of primary nonepithelial neoplasms of the stomach and small bowel.[1] They arise from cells located in the walls of the organ and show a remarkable variability in their differentiation pathways. This has resulted in a considerable degree of confusion in their interpretation, which if anything it has exacerbated recently. For many years, they were all regarded as being basically of smooth muscle nature and designated as leiomyomas and leiomyosarcomas when composed of spindle cells and as benign or malignant leiomyoblastomas (or epithelioid leiomyomas and leiomyosarcomas, respectively) when composed of epithelioid cells.[1] The many immunohistochemical and ultrastructural studies that have been carried out by numerous authors in recent times have shown a much more complex picture.[1] We report herewith a case of intraluminal GIST of the stomach.
