Endometrial polyps in female allograft recipients with abnormal bleedings.

Introduction: Endometrial polyps are a common focal endometrial pathology, with abnormal uterine bleeding (AUB) as a predominant symptom. Although the great majority of cases are benign, premalignancy or malignancy may develop within the polyp. The need for chronic immunosuppressive therapy in solid organ transplanted patients is associated with a significantly increased risk of malignant lesions.
