Table 1 The arrangements and morphological characteristics of common benign and malignant cells in endometrium
lesion types | cell arrangements | morphological characteristics |
|---|---|---|
endometrial polyps | evenly distributed and arranged in flakes | The cells are round and oval, with the same size and equal cell spacing |
S or C hyperplasia | evenly distributed and closely arranged | The cells are round and oval, similar in size, increased in number and decreased in cell spacing |
atypical hyperplasia | crowded, overlapping, and two-dimensional flat sheet distribution has disappeared | Enlarged nuclei are within three times compared with that of normal endometrial nuclei |
adenocarcinoma cells | atypical adenoid arrangements with obvious three-dimensional sense | Significantly enlarged nuclei are more than three times compared with that of normal endometrial cell nuclei, and shows some unique features |
