ABSTRACT
Müllerianosis is an embryonic Müllerian disease, resulting in the formation of the benign diseases adenomyosis, endometriosis, endosalpingiosis, and endocervicosis. Endocervicosis primarily affects the bladder, and rarely the cervix. Cervical endocervicosis, which is also a pseudoneoplastic glandular lesion, could be misinterpreted as a premalignant or even a malignant lesion. Because the treatment of these diseases is very different, early clinical diagnosis is important. Unfortunately, however, this lesion is difficult to diagnose preoperatively using clinical and radiological information, and pathological confirmation is needed. Herein, we report a rare case of cervical endocervicosis that was difficult to diagnosis preoperatively.

Endocervicosis refers to the presence of benign mucinous glands of endocervical type in ectopic site. It is rare and usually detected incidentally by histologic examination. The urinary bladder is the most common site, but peritoneum, small bowel, abdominal scar, outer wall of the cervix, vagina, and lymph nodes have been documented. Because this is the first documented report of endocervicosis arising in the rectus muscle in korea, we report this with a brief review of the concerned literatures.

This case reports muellerianosis of the urinary bladder, showing glandular lesions made up of endocervical type glands, in a 36-yr-old woman. The patient presented with lower abdominal discomfort and pain on voiding. The patient had undergone two Cesarean sections 5 yr and 3 yr earlier. On a pelvic ultrasonography, a well-circumscribed mass, 2.2x0.8 cm in dimension, was found with luminal polypoid projection in the posterior wall of the urinary bladder. The patient had a transurethral resection of the bladder mass. Histologically, the tumor was composed of irregularly shaped glands lined by endocervical mucous epithelium in the muscularis propria of the urinary bladder. Some glands exhibited cystic dilatation and contained mucinous secretions. The glands elicited no desmoplastic tissue reaction. The intraluminal mucin often contained polymorphonuclear leukocytes. The glands were mostly lined by tall columnar and bland looking mucous cells with mucin secretion. The ciliated cells were rarely observed. No endometrial component is noted. It would be appropriate to designate this lesion as "Muellerianosis of the urinary bladder, endocervicosis type". Awareness of the lesion and attention to its typical histologic features should facilitate its crucial distinction from adenocarcinoma.
