Endometrial adenofibroma: a rare entity

Mesonephric-like adenocarcinoma arising from endometrioid adenofibroma in a patient with in-utero exposure to diethylstilbestrol: A case report

Mesonephric-like adenocarcinomas are newly classified rare neoplasms of the upper genital tract. They share identical features with mesonephric adenocarcinomas, with the exception of location. There is ongoing discussion on whether mesonephric-like adenocarcinomas arise from mesonephric remnants or are of Müllerian origin. A 65-year-old woman (G2P1) presented with pelvic pain. Transvaginal ultrasound revealed multiple fibroids, and a robotic total laparoscopic hysterectomy with bilateral salpingo-oophorectomy was planned. Intraoperatively, a complex mass with cystic and solid components was found on the left ovary, which also adhered to the rectosigmoid colon. Pathologic reports documented mesonephric-like adenocarcinoma that appeared to be arising in association with an endometrioid adenofibroma. This case is notable due to the patient's unique background of in-utero exposure to diethylstilbestrol (DES) and multiple gynecological malignancies within her mother, as well as the associated endometrioid adenofibroma. This case contributes evidence to two seemingly opposing theories of mesonephric-like adenocarcinoma histogenesis: the mesonephric remnant theory (supported by the patient's DES exposure), and the Müllerian theory (supported by the associated endometrioid adenofibroma).

Cervical adenofibroma without clinical symptoms: report of a rare case

Adenofibroma is an extremely rare benign biphasic tumour composed of glandular and fibrous tissues. It occurs more often in the endometrium but it can also occur in the cervix and extrauterine sites. This case report describes a 39-year-old asymptomatic woman with cervical adenofibroma. The patient was treated successfully with surgical removal of the tumour. As adenofibromas are very rare, the report is presented with a brief review of the literature.

Magnetic Resonance Imaging and Flexible Hysterofiberscopic Findings of a Uterine Adenofibroma: Case Report and Literature Review

To our knowledge, highly detailed findings of flexible hysterofiberscopy in patients with adenofibroma have not been described. A 75-year-old nulliparous asymptomatic woman presented with a uterine polyp, which exhibited punctate heterogeneous hyperintensity or islands of isointense-to-hypointense signals on T2-weighted magnetic resonance imaging (MRI), hypointense signals on T1-weighted images (T1WI), and a little enhancement on contrast-enhanced T1WI. Flexible hysterofiberscopy revealed a red-pink polyp with a white-yellow, cobblestone-like surface easily deformed by perfusion fluid. The tumor was diagnosed histologically as an adenofibroma. Total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed. The tumor in the uterus was necrotic macroscopically and histologically, and a residual adenofibroma could not be confirmed. At present, two years after surgery, the patient remains healthy. MRI and hysterofiberscopy can reveal the histological features of uterine adenofibromas and be useful for their diagnosis.

Intramural florid cystic endosalpingiosis of the uterus: a case report and review of the literature

OBJECTIVE

We report a case of intramural florid cystic endosalpingiosis in the lower uterine segment of the uterus.

CASE REPORT

A 43-year-old female presented with vaginal bleeding. Abdominal computed tomography suggested a leiomyoma with cystic degeneration. A total hysterectomy revealed a 4.0 cm × 3.8 cm cystic mass in the lower uterine segment. The cystic space microscopically was lined with a single layer or stratified layer of ciliated columnar cells that resembled tubal epithelium without cytologic atypia. The glandular spaces were surrounded by normal myometrium with no evidence of periglandular endometrial stroma, which was consistent with the diagnosis of florid cystic endosalpingiosis.

CONCLUSION

Florid cystic endosalpingiosis involving the uterus is a rare and clinically unexpected finding; however, it should be considered in the differential diagnosis of a uterine mass.

Adenofibroma in a young patient: a rare entity in an uncommon age

Adenofibroma is an extremely uncommon benign tumor composed of glandular and fibrous tissues. It occurs more often in the endometrium but it can also occur in the cervix and extrauterine sites. We report a case of a 32-year-old asymptomatic woman with cervical adenofibroma, first detected in a routine endovaginal ultrasound, as a cervical mass containing multiple cystic components. Histopathologic findings diagnosed its nature. As adenofibromas are very rare, we present this case with a brief review of the literature.

Adenofibroma of Skene's Duct: A Case Report

Skene's glands, also known as paraurethral glands, are homologues of the male prostate, in which painless cystic masses and inflammation due to obstruction have been rarely found and reported. In addition, there have been rare reported cases of adenocarcinoma of Skene's glands. Recently, the authors experienced the first case of adenofibroma arising in Skene's glands of a 62-year-old woman with coital pain. Hereby, we present the case with pathologic and immunohistochemical findings and a short review of literature.

Lipoadenofibroma of the endometrium: a rare variant of benign mullerian mixed tumor

OBJECTIVE

Adenofibroma is a form of mixed mesodermal tumor in which epithelial and stromal components are benign, and usually arises in the endometrium of postmenopausal women. We report a case of lipoadenofibroma of the endometrium that appeared as an intracavitary mass, which is very unusual because endometrioid adenofibroma rarely contains mature adipose tissue, only the second such case described in detail.

CASE

An endometrial polypoid mass measuring 1,5 cm with maximum diameter was found incidentally during total abdominal hysterectomy for keratinizing large cell carcinoma of the cervix in a 60-year-old woman. The endometrial polypoid mass was found to be a lipoadenofibroma composed predominantly of collagenated fibrous stroma populated by cystically dilated and occasionally crowded glands lined with proliferative endometrium, intermingled with abundant mature adipose tissue.

CONCLUSION

We suggest that uterine adenofibromas with lipomatous areas belong to the family of mixed tumor of Mullerian origin. We discuss the pathogenesis of this entity and review the previously documented similar cases.
