Benign glandular inclusions in lymph nodes, endosalpingiosis, and salpingitis isthmica nodosa in a young girl with clear cell adenocarcinoma of the cervix.

A 12-year-old girl underwent radical surgery for clear cell adenocarcinoma of the endocervix. Bilaterally dilated fallopian tubes with hyperplastic mucosal folds and salpingitis isthmica nodosa were found in association with benign glandular inclusions in a para-aortic lymph node and in the serosa of pelvic organs. Changes in the müllerian-derived epithelium appear to be a common denominator of these unusual lesions in this young girl. A primary growth disturbance of the cells of the müllerian system, which was conditioned during embryonic development and manifested itself later in life in response to appropriate stimuli associated with menarche, is postulated as the underlying abnormality.
