Classification of adnexal masses based on morphological appearance

Classification of adnexal masses basing on morphological appearance
Cystic unilocular (benign)	non ovarian	paraovarian cysts, hydrosalpinx, pyosalpinx and hematosalpinx
	ovarian	functional cysts and serous cystadenomas (common)
		cystadenofibromas and mucinous cystadenomas (less common)
Cystic multilocular (benign and borderline)	endometriomas, mucinous cystadenomas and borderline tumours (common)
	serous cystadenomas (less common)
Cystic and solid (benign, borderline and malignant)	benign	mature cystic teratoma
	borderline to malignant	surface epithelial tumours, metastasis, Yolk sac, granulosa cell and Sertoli-Leydig tumours
Predominantly solid (benign, borderline and malignant)	benign	Brenner tumour, fibrothecomas
	borderline to malignant	serous and mucinous carcinomas, dysgerminoma and Yolk sac tumour, granulosa and Sertoli-Leydig cell tumours, metastasis
