title: Recently described entities in the gynaecological tract.
abstract: In recent years there have been significant advances in our understanding of female genital tract tumours due to the fact that new molecular abnormalities and translocations have been identified in certain neoplasms. Also, terminology of various lesions in the gynaecological tract has changed and a couple of new entities have been described.In this review we will highlight some mesenchymal neoplasms including gynaecological perivascular epithelioid cell tumour (PEComa), inflammatory myofibroblastic tumour (IMT) occurring in the uterus and discuss and review terminology of endometrial stromal neoplasms.A recently described entity, gastric type endocervical adenocarcinoma will be reviewed, summarising its most salient microscopic and clinical features. The newly proposed endocervical adenocarcinoma classification system by Silva and collegues will be reviewed as well.Finally, a particular high-grade endometrial carcinoma (undifferentiated endometrial carcinoma) will be discussed highlighting the importance of its recognition and differential diagnosis.
