Type of Preparation: Conventional Magnification: Medium Clinical History: The patient is a 49 year old female without symptoms, routine visit Interpretation: NILM Cytomorphologic Criteria: Large clusters of spindle cells with inconspicuous cytoplasmic borders. Explanatory Notes: Sometimes fragments of lower uterine segment are abraded and do not contain simple tubular glands. Close attention to the large fragments and delicate spindled nuclei suggests abraded endometrial stroma. Abraded endometrium does not carry the same implication of risk for endometrial carcinoma that exfoliated endometrium does. LUS should be reported as "NILM.". Follow-up: Free of abnormality for 10 years
