A Rare Case of a Large Mucinous Cystadenoma of the Tail of the Pancreas

Mucinous cystadenomas are part of the cystic tumours of the pancreas. They are benign tumours whose malignant potential recommends surgical resection. They are often discovered incidentally, in 75% of cases. These tumours have radiological characteristics that suggest the diagnosis. There are known radiological criteria predictive of malignancy, including a tumour diameter ≥ 3cm. Furthermore, the diagnosis of certainty is provided by anatomopathological examination. Practitioners must bear in mind the existence of these tumours, their malignant potential, and the possibility of a benign nature despite the presence of radiological criteria predictive of malignancy. Treatment consists of surgical resection without cystic rupture in order to prevent the risk of recurrence.
