You answered: High-Grade Squamous intra-epithelial lesion
Sorry, that is INCORRECT
The correct diagnosis is: Endometrial adenocarcinoma
- The smear shows loosely cohesive sheets of cells with nuclear overlapping and lack of polarity.
- There are normal endocervical cells in the background, some ciliated and degenerated inflammatory cells.
- The abnormal cells have granular cytoplasm, increased N/C ratio, nuclear irregularity in shape and size, hyperchromasia and irregularity in the nuclear outline with finely to coarsely granular chromatin.
- Two groups of loosely cohesive clusters are depicted, one forming an acini and the other showing lack of polarity, and gland cells with cilia in the background.
- There is an increase in N/C ratio, pleomorphic nuclei with irregular nuclear outline, hyperchromasia and coarse chromatin pattern in the abnormal cells.
- The biopsy showed endometrial adenocarcinoma of endometrioid type of mixed glandular and solid pattern, with 4mm deep stromal invasion of the endocervix.
- The majority of low-grade uterine carcinomas are endometrioid endometrial carcinomas but they can also exist as a high grade tumour.
- Low-grade tumours (well-differentiated Grade 1) show a predominantly glandular or villoglandular growth pattern with slight nuclear enlargement and small nucleoli.
- Moderately-differentiated endometrioid carcinomas (Grade 2) diverge from glandular or papillary to solid sheets of cells (6 – 50% of the tumour) and have enlarged nuclei relative to Grade 1 tumours but nuclear pleomorphism and chromatin clumping is less than a Grade 3 tumour.
- High-grade tumours (Grade 3) show increased areas of solid growth with cells that are no longer recognizable as columnar, having more pleomorphic nuclei, prominent nucleoli and chromatin clumping.
