[Malignant paraganglioma of the uterus].

We report a malignant uterine paraganglioma in a 41-year-old woman who underwent a hysterectomy for meno-metrorrhagia. It was initially thought to be a leiomyoma in necrobiosis. The clinical outcome was characterized by an early regional recurrence (in the left Fallopian tube). Later, vertebral and lung metastasis occurred, leading to death 22 months after the initial diagnosis. Paragangliomas are uncommon neuroendocrine tumors, related to pheochromocytomas. They are mainly found in the para-aortic and retroperitoneal region, and less commonly in the pelvic area. Location in the uterus is extremely rare: 5 cases were previously reported and only one malignant.
