Endometrial biopsies are useful for evaluating endometrial disease, but the presence of non-endometrial, noncervical tissue is rare and is typically restricted to metastasis to the endometrial cavity. We report, for the first time, a case of an endometrial biopsy seeded with serous cells in a young patient with a known history of a serous borderline tumor of the ovary. Given the patient’s diagnosis of an ovarian serous borderline tumor, the most likely explanation for the presence of serous cells in her endometrial biopsy is transit via the fallopian tube into the endometrial cavity. The morphologic and IHC profile of the cells from the endometrial biopsy were consistent with that of the ovarian tumor counterpart. The impact of this finding on tumor prognosis cannot be determined, and follow-up should be observed.
