Gastrointestinal stromal tumours represent a group of non-epithelial gastrointestinal tumours that have both benign and malignant character. Most frequently, they occur in the stomach and the intestine; however, as regards their overall incidence, they are rather infrequent tumour lesions. The present case report describes a rare bulky extragastrointestinal stromal tumour originating from the mesenterium in a young patient. Its anatomical and histological picture, diagnosis and treatment are described. Our work points to the necessity for physicians to also bear in mind the less likely options and highlights the role of surgery in the treatment of such voluminous findings.
