BENIGN CYSTIC TERATOMA OF OVARY
This patient was a young woman who presented with an 18-month history of lower abdominal pain worse during pregnancy.
The specimen is an opened, thin-walled cyst 10 cm in maximum diameter. The lumen contains a tangled mass of hair which is arising from a rounded elevated area covered with skin in the posterior wall of the cyst. Below this mass there are two incompletely formed teeth. Posteriorly the cyst appears to be arising from the ovary. The attached fallopian tube is normal. This is a benign cystic teratoma of the ovary.
This is the commonest germ cell tumour of the ovary.
