all of these tumors originate from the coelomic epithelium at any of various stages of its differentiation into the derivatives of the mullerian duct , giving rise to a large group of tumors that can be subdivided into serous papillary cyst-adenocarcinomas arising from surface-like epithelium , mucinous cystadenocarcinomas arising from endocervical-like epithelium , endometrioid carcinomas from endometrium-like epithelium , clear-cell carcinomas from endocervical or endometrium-like epithelium , malignant cystadenofibromas from undetermined pluripotent mullerian epithelium , and ( malignant ) brenner tumors from heterotopic epithelium resembling wolffian differentiation , as seen in the urothelium .
