Objective: To determine the epidemiological and sonographic characteristics of patients with endometrial carcinoma of endometrioid and non-endometrioid subtype to analyse if any differences can be observed between the groups.

Study design: A case-control study was performed considering 122 patients with endometrial carcinoma where 96 (78.69%) had endometrioid carcinomas (controls) and 26 (21.31%) had non-endometrioid carcinomas (cases). Epidemiological, clinical, and sonographic variables (endometrial thickness and sonographic suspicion of myometrial invasion of the tumour) were analysed. Qualitative variables were studied with the Chi-square test and the Fisher’s exact test and quantitative variables with the t test. A value of p 0.05 was considered statistically significant.

Results: Tumours of the non-endometrioid type are observed in older patients (p = 0.003) and frequently show a higher sonographic tumoral invasion (p = 0.0036).

Conclusions: This study supports previous observations that non-endometrioid endometrial carcinomas present at older ages and provides new data that non-endometrioid carcinoma more frequently show sonographic images compatible with myometrial invasion.
