Psammoma bodies and cells from in situ fallopian tube carcinoma in endometrial smears: a case report.

BACKGROUND

Primary in situ fallopian tube carcinomas are rarely diagnosed, and malignant cells from this lesion have not been previously described as occurring in endometrial smears.

CASE: A 57-year-old, postmenopausal woman had an endometrial smear that revealed adenocarcinoma cells associated with psammoma bodies. She also had smooth muscle cells in the smear compatible with uterine leiomyomas. Examination of the hysterectomy specimen disclosed a primary in situ carcinoma of the left fallopian tube and uterine leiomyomatosis.

CONCLUSION

Endometrial cytology plays an important role in the diagnosis of pathologic processes in the uterus. It may also contribute useful information on extrauterine diseases.
