The specimen consists of a left ovary which has been sectioned longitudinally. Attached to the
ovary is the fallopian tube. The ovary is expanded by a large tumour mass which contains a variety
of tissues. The majority of the tumour is composed of sebaceous material which contains hairs.
Several cystic structures are seen superiorly and immediately adjacent to the ovarian hilum. The
hilar portion of the ovary is oedematous as is the fallopian tube and there are extensive areas of
subcapsular haemorrhage. The features are those of a benign cystic teratoma which has undergone
torsion. The tumour was found in a 31 year old female who presented with abdominal pain.
