Malignant endometrioid cystadenofibroma of the ovary

Large functional benign endometroid cystadenofibroma of the ovary leading to endometrial cystic glandular hyperplasia and postmenopausal bleeding

Benign endometroid cystadenofibroma of the ovary is a rare tumour with few reported cases. The association of endometroid cystadenofibroma with endometrial cystic glandular hyperplasia has not been previously reported to authors' knowledge. We are reporting a 75-year-old postmenopausal woman who presented with a large abdominopelvic mass corresponding to 30 weeks size gravid uterus and postmenopausal bleeding. She has a well-oestrogenised vagina. Ultrasound pelvis revealed a large cystic mass extending from pelvis to epigastrium with no solid component and few incomplete septations and no internal echoes. MRI findings showed mainly cystic component with few moderately enhancing, fine, incomplete septa. Endometrial aspiration reported histopathology of cystic glandular hyperplasia without atypia. Serum oestrogen level reported to be high (210 pg/mL). Hysterectomy with bilateral salpingo-oophorectomy was performed. Histopathology of the specimen revealed benign endometroid cystadenofibroma. She remained asymptomatic and disease free during her 6-month follow-up.

The association of benign and malignant ovarian adenofibromas with breast cancer and thyroid disorders

An unexpected association with breast cancer and thyroid disorders was found during a review of 91 cases of benign and malignant ovarian adenofibromas. Sixty-three tumors were benign, 11 had areas of borderline neoplasms, and 17 had a component of carcinoma. Such tumors were divided into glandular/cystic (61 cases) and papillary (30 cases) according to their gross and microscopic appearance. Among the 61 patients with glandular/cystic adenofibromas, 13 (21%) had breast cancer and 19 (31%) also had thyroid disorders. Among the 30 patients with papillary adenofibromas there were no cases of breast cancer and only 2 patients had thyroid disorders. The average age of the patients with ovarian adenofibroma and breast cancer or thyroid disorders was higher (66 years) than that of patients without breast cancer or thyroid disorders (55 years). More patients with breast cancer and thyroid disorders had bilateral adenofibromas than patients without breast cancer or thyroid disorders. We also reviewed the medical records of 100 patients with ovarian cancer without adenofibroma component, 100 patients with breast cancer, and 100 patients with ovarian and breast cancer. Six percent of patients with ovarian cancer had breast cancer and 16% of each one of these groups had thyroid disorders. This unexpected association found between glandular/cystic adenofibromas, breast cancer, and thyroid disorders might be explained by defects common to these organs. Disorders of some of these organs have been linked by common genetic changes and it is known that these organs are under the influence of similar hormones. Mutations of PTEN have been found in breast and thyroid cancer. The thyroid and ovaries are controlled by glycoprotein hormones of the pituitary gland, which have common alpha subunits.

Ovarian endometrioid adenocarcinoma coexistent with benign and borderline endometrioid adenofibroma: a case report

A well-differentiated endometrioid adenocarcinoma coexistent with benign and borderline-malignant endometrioid adenofibroma was found in the ovary of a 64-year-old woman. She had vaginal bleeding caused by simple hyperplasia of the endometrium due to high levels of sex steroid hormones. A FIGO stage Ia solid ovarian tumor was identified. It was composed of irregularly shaped endometriotic glands with benign and borderline malignant cytologic features embedded in abundant fibromatous stroma. Well-differentiated malignant epithelium was adjacent to these areas, but fibromatous stroma was not predominant. She was treated by surgery and three cycles of chemotherapy. This paper describes this unusual tumor and reviews the literature.

Cystadenofibroma of the ovary in young women

Cystadenofibroma of the ovary, a relatively rare benign tumor, usually appears during the fourth and fifth decades. This tumor has malignant ultrasonographic features and may also macroscopically appear as malignant during surgery. Since this tumor has a rare malignant potential, it is well-advised to be aware of the possibility of a cystadenofibroma before selecting an aggressive surgical approach in young patients. We present five cases of young patients with cystadenofibromas of the ovary.
