Uterine corpus, Endometrial carcinomas, Carcinosarcoma


Background: The uterine corpus represents the second most common site for malignancy in the female genital tract. This study was performed to ascertain the profile of malignant tumours of the uterine corpus reported at our centre.

Methods: A retrospective analysis of cases retrieved from the archives of the department of pathology from January 2014 to December 2016. Clinical information of the patients was collected from the hospital records.  Classification and grading of the tumours were done according to the current WHO classification.

Results: Nineteen cases were studied. There were ten cases of endometrial adenocarcinoma, five cases of leiomyosarcoma, three cases of endometrial stromal sarcoma and one case of carcinosarcoma(malignant mixed mullerian tumour). The age range of endometrial adenocarcinoma was 55 to 85 years and presented with post menopausal bleeding, whereas endometrial stromal sarcomas occurred in women above 45 years of age. Leiomyosarcomas had age range from 26 to 65 years. All leiomyosarcomas were clinically diagnosed as fibroid. Majority of endometrial adenocarcinomas were well differentiated endometroid type. Out of the three endometrial stromal sarcomas two were high grade, one with metastasis. All leiomyosarcomas showed mitotic rate above 10/10hpf.

Conclusions: Endometrial carcinomas form the majority of malignant tumours of uterine corpus and occur in older age group followed by leiomyosarcomas. Endometrial stromal sarcomas are less common and occur in middle aged and older patients. Leiomyosarcomas and stromal sarcomas are usually misdiagnosed as fibroids clinically unless metastases are present.
