Neuroendocrine carcinoma of the uterine cervix with extensive pagetoid spread pattern.

ABSTRACT

There have been no reported cases of neuroendocrine carcinoma (NEC) of the cervix with pagetoid spread (Pag-S). A 44-year-old woman came to our department because of abnormal cytology that persisted immediately after a radical hysterectomy for NEC of the cervix. A mapping biopsy in a large area from the vaginal wall to the vulva revealed that synaptophysin/Ki-67-positive tumor cells were scattered within the epithelium in multiple areas, suggesting a wide Pag-S of NEC. Because tumor cells were found beyond the vaginal wall, the anterior pelvic exenteration was performed. Since we could pathologically confirm the complete resection and no distant metastases were detected, no adjuvant therapy was performed. Four years have passed since the initial treatment without any tumor recurrence. It is known that the prognosis of NEC of the cervix that invades beyond the cervix is poor; however, if there is a Pag-S pattern, a radical surgical treatment can be considered.
