Mucinous borderline tumor of the ovary, endocervical type

These images were taken from a multicystic, 12 cm ovarian tumor in a 67 yo patient. After extensive sampling the diagnosis of a mucinous borderline tumor of the ovary, endocervical type was made.

Comment: Personally, I do not remember having encountered an endocervical type mucinous borderline tumor of the ovary, usually they are of intestinal type.
