Which is the most common histological subtype of endometrial carcinoma?

• A Endometrioid adenocarcinoma ✓
• B Clear cell carcinoma
• C Uterine serous carcinoma
• D Mixed Mullerian tumour

Explanation

Endometrioid adenocarcinoma accounts for approximately 80 to 85 percent of endometrial carcinomas and is typically oestrogen dependent, arising against a background of hyperplasia. Uterine serous carcinoma contributes roughly 10 percent and clear cell about 4 percent, both belonging to the biologically aggressive Type II category. The key fact that eliminates the distractors is that serous and clear cell types, although high yield, together form a minority of cases.
