Uterine serous carcinoma (USC) commonly arises on the surface of endometrial polyps in the background of an atrophic endometrium, and the most representative non-endometrioid endometrial carcinoma is serous uterine carcinoma (USC), which accounts for about 10% of all endometrial cancers. Endometrioid carcinoma of the endometrium is the most common histological subtype of endometrial cancer, accounting for 85 - 90% of cases. It is generally associated with a lower risk for progression and favorable prognosis, particularly for low-grade disease. USC is microscopically characterized by (1) papillae with or without a fibrovascular core, (2) marked nuclear atypia, (3) slit-like spaces, (4) solid growth, (5) scant cytoplasm. Despite being the second most common type of endometrial cancer, USC is still considered a relatively rare tumor. Patients with USC are often diagnosed at an earlier disease stage than endometrioid subtype endometrial cancer but remain at a higher risk for relapse and ha...
