Abstract

Uterine adenofibroma is a rare benign neoplasm that is classified into the mixed epithelial and mesenchymal tumor group. It typically affects the endometrium; involvement of the cervix is an unusual condition. We present a 55-year-old woman with the complaint of perimenopausal genital bleeding. Her gynecologic examination revealed a firm, pedunculated 2 × 2 cm polypoid lesion on the cervix. A diagnostic polypectomy was performed and histopathological findings of the cervical biopsy specimen confirmed the diagnosis cervical adenofibroma. Although this lesion appears to be histological benign, multiple recurrences, local invasion, and involvement by adenocarcinoma have been reported. Therefore, total hysterectomy with bilateral salpingoophorectomy was performed.

Introduction

Uterine adenofibroma was first described by Ober in 1959 as a form of mixed mesodermal tumor in which the stromal and epithelial components are benign. Cervical adenofibroma is a rare disorder and accounts for 10% of uterine adenofibromas. The tumor is clinically and histologically benign [1, 2]. However, multiple recurrences [3], local invasion [4] and involvement by adenocarcinoma [5] have been reported. Adenofibromas occur most frequently in peri- or postmenopausal women and symptoms are usually abnormal genital bleeding [6].

We present a patient with an adenofibroma of the uterine cervix.

Case report

A 55-year-old- woman, gravida 4 para 4, was admitted to the gynecology clinic at Siirt Women's Health and Children's Hospital in January 2007 with the chief complaint of genital bleeding that she had been experiencing for about 3 months. Her past medical history included hypertension.

Gynecologic examination revealed a firm, pedunculated 2 × 2 cm polypoid lesion on the cervix and slightly enlarged uterus. Laboratory data were unremarkable. A diagnostic polypectomy was performed. Microscopically, the tumor consisted of benign dilated cystic endometrial glands and stromal components. Histopathological findings of the cervical biopsy specimen confirmed the diagnosis cervical adenofibroma (Fig. 1).

The tumor consisted of an admixture of fibroconnective tissue which forms papillary projections and large irregular glands lined by endocervical-type epithelium

At laparotomy, examination of the pelvis revealed a slightly enlarged uterus. Total hysterectomy with bilateral salpingoophorectomy was performed. Postoperative pathological examination revealed that this lesion did not extend to the endometrium.

Discussion

Mixed mesodermal tumors contain both epithelial and mesencymal cells, which comprise a rare group of uterine lesions, and the exact clinical and pathological features of the lesions are still being defined. They can be subdivided into benign and malignant lesions. Benign lesions include adenofibroma and adenomyoma. Malignant lesions include adenosarcoma, carcinosarcoma (malignant mixed tumor), and carcinofibroma.

Adenofibroma most commonly arises from the endometrium, but 10% of the tumors originate in the cervix [7]. They usually present as broad-based polypoid masses that often have villous and spongy cut surfaces with cystic spaces surrounded by firm tissue [8].

Adenofibromas can be seen in patients of any age, but they occur most frequently in peri- or postmenopausal women [6]. The most common presenting symptom is abnormal vaginal bleeding. Some patients have a history of prior removal of polyps or a history of tamoxifen therapy [9].

It is clinically important to distinguish adenofibromas from adenosarcomas. Clement and Scully [7] have recommended the following criteria for the pathologic diagnosis of adenosarcoma rather than adenofibroma when one or more of the following signs are present: a stromal mitotic count of ≥2 per 10 high power fields (HPF), marked stromal cellularity, and more than mild degrees of stromal nuclear atypia. On the other hand, Zaloudek et al. [10] suggested that adenosarcomas should be diagnosed when mitosis is more than 4 cells in 10 HPF. The histological differential diagnosis of adenofibroma and adenosarcoma includes endometrial polyps, which are at the benign end of the histologic spectrum, and carcinosarcoma and endometrial stromal sarcoma, at the malignant end.

Hysterectomy is the preferred treatment for an adenofibroma because the neoplasm may recur if it is not completely curetted or excised [3]. Moreover, there is a report that adenofibromas can change to adenosarcomas [3].
