- Abstract:
- OBJECTIVE: This study was undertaken to determine the incidence and distribution of the location of benign müllerian inclusions in pelvic and paraaortic lymph nodes. METHODS: A total of 114 patients operated on for gynecologic malignancy between 1995 and 1998 underwent surgery including systematic pelvic (n = 114) or pelvic and paraaortic (n = 70) lymphadenectomy. The lymph node material was labeled according to anatomic origin, immediately fixed en bloc, embedded in paraffin, and processed as step-serial sections at intervals of 400 microm. The 5-microm-thick sections were stained with hematoxylin and eosin. RESULTS: Overall, 26 of 114 patients (23%) had benign müllerian inclusions. Inclusions were most common in the paraarotic (34%), external iliac (12%), and common iliac (9%) regions (P > 0.05). Multiple anatomic sites were involved in 14 of 26 patients (54%). Two women had paraaortic inclusions and negative pelvic nodes. Benign müllerian inclusions were seen in 13 of 51 patients (24%) with ovarian carcinoma, 11 of 47 (23%) with cervical carcinoma, 1 of 9 (11%) with endometrial carcinoma, and 1 of 2 with ovarian serous borderline tumor, (P > 0.05). CONCLUSIONS: Benign müllerian inclusions occur in approximately one-fifth of patients with gynecologic malignancies in all anatomic regions of pelvic and paraaortic lymph nodes. They must be distinguished from metastatic deposits.
