Popis: ullerian adenosarcoma is a rare tumor, accounting for only 8% of all uterine sarcomas, and it usually originates in the endometrium, growing as a polypoid mass. The median age is 58 years, but the tumor can occur even in the teenage years as well as old age. If it is found before deep myometrial invasion, the prognosis is generally good.1 The correct pathologic interpretation, however, can be difficult, thereby delaying appropriate therapy. Amant et al2 reported that 6 of 15 patients had misdiagnosis by pathologists, noting a confusion with benign leiomyomas. For most patients, the cancer has spread by the time of diagnosis, with only 35% of a series of 20 patients having disease limited to the endometrium as reported by Huang et al.3 The 5-year survival was reported by Bodner et al4 to be in the range of 62% in a series of 31 patients. Abnormal bleeding is the most notable symptom.1 There may be an increased risk of development of this cancer after tamoxifen therapy.5 Recently, Timmerman and associates6 described the “pedicle sign” when a “feeding artery” leading to the endometrium was imaged. Finding such an artery had sensitivity of 76.4% and specificity of 95.3% for endometrial polyps.6 We present a case in which the feeding artery sign was the only imaging abnormality in a patient with an adenosarcoma of the endometrium.
