Two casesof primary paraovarian-origin serous cystadenocarcinema, one invasive and one of low malignant potential, are presented. Both were diagnosed in postmenopausal women and were initially treated surgically. As of this writing, both women have survived 48 months past their initial diagnosis and have no clinically detectable disease. Clinical aspects and management problems of this fairly recently identified and rare entity are discussed and the literature on primary paraovarian malignant epithelial tumors is reviewed. o IWO Academic press, IIK.
INTRODUCTION Primary malignant paraovarian epithelial tumors (PMTs) are extremely rare and, including the present two cases, only 20 such neoplasms have been documented in the English literature [l-17]. Paraovarian epithelial tumors were initially considered to be of wolffian (mesonephric) origin, but studies by Gardner et al. [3] have revealed that most of these tumors are of mtillerian (paramesonephric) origin. They also have established the histological criteria for determining the origin of these tumors [15]. Whether the origin is wolffian, mtillerian, or mesothelial metaplasia probably is unimportant when management methods and related problems are to be considered. Also, whether these rare neoplasms differ from their ovarian counterparts, in their invasive or lowmalignant-potential (LMP) forms and in their clinical and ’ To whom correspondence and requests for reprints should be addressed. * All authors are also affiliated with the Sackler School of Medicine, University of Tel Aviv.
biological behavior, has yet to be determined. According to the accepted histological criteria, the two cases presented here were found to be of mtillerian origin [3-151. CASE REPORT Case I A 76-year-old Caucasian P,G2 was referred to the gynecological ward in March 1985 for investigation of a pelvic mass and a significant enlargement of her abdomen 3 months prior to admission. General examination raised the possibility of ascites, although liver and spleen were not palpable. Pelvic examination revealed a small uterus, but both adnexae could not be palpated due to a large amount of ascites. A large mobile mass was felt in the pelvis. Ultrasound examination was suggestive of an ovarian multilobular cystic mass. Preoperative investigations were without any pathological findings. At laparotomy, 6 liters of ascitic fluid was aspirated. The abdominal cavity was surveyed and no special findings were detected. Examination of the pelvis revealed a normal-size uterus, with normalappearing ovaries and fallopian tubes. The left adnexa contained a large, multilobular dark-colored cystic mass which was located within the leaves of the broad ligament adjacent to the ovary. No peritoneal implants were identified. Total abdominal hysterectomy (TAH) and bilateral salpingo-oophorectomy (BSO) were performed. The postoperative course was uneventful and the ascites disappeared subsequent to surgery. Cytological assessment of the ascitic fluid revealed no malignancy. Histological examination of the mass !68

CASE REPORT
showed a well-differentiated serous cystadenocarcinoma arising in a parovarian cyst, with capsular invasion. She has been regularly followed and was 53 months postdiagnosis, with no clinical evidence of disease, at the time of this writing.
The postoperative course was uneventful. The final histology of the tumor showed an LMP serous cystadenocarcinoma arising from a parovarian cyst. The peritoneal washings were negative for malignancy. As of this writing, she is 51 months postsurgery, with no clinical evidence of disease.
Case 2 A 54-year-old Caucasian, G2P,, was admitted to the gynecological department in July 1985. She had been complaining of a recent enlargement of her abdomen. Her past medical history was not contributive regarding the actual complaints. On admission, she was found to be in general good health, with no noteworthy pathological findings. Pelvic examination revealed a huge cystic mass reaching the lower right rib cage. The uterus was slightly enlarged and neither adnexa could be palpated. On ultrasonic examination, the cystic mass was thought to be of left ovarian origin with several large papillary projections arising from the interior wall. Clinical and laboratory examinations were within normal limits. A laparotomy was performed. No peritoneal effusion was observed. A multilobular cystic smooth mass was found arising from and attached to the right, broad ligament. The right ovary, fallopian tube, adjacent structures, left adnexa, and slightly enlarged uterus were normal in appearance. A survey of the rest of the abdominal cavity revealed no palpable lymph nodes or tumor implants. Following pelvic and abdominal washings, the cystic mass was removed, and TAH, BSO, and an infracolic omentectomy were performed.

PATHOLOGY Case 1 The surgical specimen that was submitted consisted of a normal-appearing left tube and ovary, with an adherent cystic mass mesuring 12 x 9 x 8 cm in its largest dimensions and located within the broad ligament. On cut section, the mass proved to be cystic and partially filled with soft, papillary structures. The lumen contained a turbid, semithick fluid. Microscopic examination of this paraovarian mass (Fig. 1) showed a cuboidal epithelium lining the smooth inner wall zones and an endosalpingeal epithelium overlying the papillary projections. A definite basement membrane was not apparent. In several places, conspicuous foci of foamy histiocytes were noted under the neoplastic epithelium. Some of the papillary structures, with a dense stroma, were covered by epithelium showing prominent heaping-up, some cellular atypia, and few mitotic figures. There also were areas in which definitive invasion of the stroma by atypical glandular structures was observed. Examination of the uterus and right adnexa revealed no noteworthy pathology.

Moreover, in at least three patients, the existence of a PMT was not identified at the time of the tumor’s reDISCUSSION moval. Only the histological diagnosis revealed its presence, and these patients underwent a reexploration to Lennox and Maegher in 1952 opened a new chapter complete surgical treatment and to assess disease status in gynecological oncology by reporting the first case of [9,13,14]. The above data show the extreme difficulty a malignant epithelial tumor of the broad ligament [l]. encountered in the empirical diagnosis of these neoplasms prior to surgery. The second important aspect in these predominantly young patients is the age factor at the time of diagnosis, which might pose critical surgical decision dilemmas, particularly for those patients wishing to preserve their childbearing options or to prevent unnecessary castration procedures. Despite the dearth of published data, the mean age has been found to be 43.1 years, with the youngest patient 13 years old. Our first case, 76 years of age, is the oldest reported patient. A diagnosis was made at 40 years and under for 47.3% (9/19) of the patients. Since the entity is rare, there is no accepted treatment plan or follow-up strategy as there is for their ovarian counterparts. Thus, surgical and additional treatment modalities for the majority of cases were empirically determined. An additional important aspect, in relation to the relatively youthful patient, is the possibility of the coexistence of these tumors with pregnancy, which has been found in 10% (2/20) of the cases [ 14,171. In our first case, the presenting symptom was ascites. Its presence in an amount disproportionate to the relative size of the tumor, with an intact capsule, the absence of tumor cells in the peritoneal effusion, and the disappearance of ascitic fluid following removal of the neoplasm are quite interesting and make this case unique, in both its clinical presentation and its disease course when compared with the other PMTs. Because the peritoneal effusion was submitted for a cytological examination, no diagnostic procedures other than TAH and BSO were employed. FIG. 2.

seven cases with invasive PMTs, only one survived more than 5 years, two died of the disease, and two were alive at the time of this writing. No data were available on the survival of the remaining two. In addition, only 3 of 11 patients with LMP PMTs were found to survive more than 5 years, and no deaths were reported in this group. When comparing our findings with the scanty literature, one should recall that most of the cases used individual management. Thus, there are no bona fide guidelines for modern management methods and follow-up modalities. The data are minimal, and it is difficult to draw conclusions on the clinical and biological behavior of these tumors. It is hoped that a general consensus on management criteria will be reaches to aid the physician in treatment decisions when such rare entities are encountered. REFERENCES 1.
