A case of lymphoma occurring in an ovarian teratoma.
BACKGROUND
We describe the discovery, by pathology, of a totally unexpected diagnosis involving an ovarian teratoma.


METHODS
A middle-aged woman underwent routine total abdominal hysterectomy and bilateral salpingoophrectomy for ultrasonically diagnosed uterine fibroids and a coexistent benign right ovarian cyst. The operative findings were of fibroid uterus and right ovarian teratoma. However, pathology revealed a malignant lymphoma occurring in, and arising from, the teratoma.


CONCLUSIONS
The routine removal of a presumed ovarian teratoma may yield unexpected results. Ovarian teratomas are indeed cellular chimeras.
