Abstract

Smooth muscle tumours of uncertain malignant potential (STUMPs) are rare neoplasms that present diagnostic difficulties due to their intermediate morphology. While they represent an uncommon uterine tumour type, extra-uterine especially in males, are exceptionally rare. This report presents a case of a STUMP in an older male patient, the origin of which could not be determined. The mainstay of treatment is surgical resection. Given this tumour type's uncertain biological potential and documented late recurrence in uterine STUMPs, prolonged surveillance is recommended.
