OBJECTIVE: This study was designed to determine the clinical significance of serum CA 125 and CA 19-9 levels in preoperative differential diagnosis of benign ovarian tumors. METHODS: 104 patients who visited the department of Obstetrics and Gynecology of Dankook University Hospital from February 1999 to December 2001, and who were diagnosed as adnexal mass and underwent surgery, and free of other medical diseases, were enrolled as subjects. An analysis of preoperative serum CA 125, CA 19-9 levels of patients was performed in correlation with the postoperative histologic diagnoses. The histologic diagnoses were grouped as mature cystic teratoma, endometrioma, mucinous cystadenoma, serous cystadenoma, benign cystic tumor group, adnexal inflammatory disease group. Study group was defined as endometrioma, adnexal inflammatory disease in CA 125, and mature cystic teratoma, endometrioma in CA 19-9, and the others were defined as control group. Statistical analysis with Chi square test was done on the number of cases who showed CA 125 or CA 19-9 increment over cut off value between study group and control group. Study group was compared with control group in the mean value of serum tumor marker level and the mean value of elevated serum tumor marker level over cut off value. RESULTS: The number of cases who showed serum CA 125 increment over cut off value (35 U/ml) was significantly higher in endometrioma and adnexal inflammatory disease group (p<0.05), and the number of cases who showed serum CA 19-9 increment over cut off value (37 U/ml) was significantly higher in endometrioma and mature cystic teratoma group (p<0.05). The mean value of serum tumor marker level and the mean value of elevated serum tumor marker level over cut off value in those groups showed no significant difference in comparison with those of the other groups. CONCLUSION: In this study, increment of CA 19-9 in endometrioma and CA 125 and CA 19-9 in mature cystic teratoma showed statistically significant higher frequency than other groups. We concluded that checking the preoperative serum level of CA 125 and CA 19-9, combined with transvaginal ultrasonography, may be helpful in differential diagnosis of benign ovarian tumors and in discriminating benign ovarian tumors from malignant ovarian tumors, if any other condition that may cause serum level elevation of CA 125 and CA 19-9 is excluded.

The purpose of this prospective study was to evaluate the diagnostic value of color Doppler scoring system in characterization of ovarian masses. We performed transabdominal or transvaginal color Doppler sonopaphy on 82 women with ovarian masses and analyzed the sonographic findings. Ovarian lesions were assessed by means of morphological and color Doppler scoring system by Kurjak. Tumors were characterized by ultrasonographic findings as benign or suspected of being malignant. Then the results of each scoring systems were correlated with histopathological findings. The results were as follows; Of 82 ovarian masses, 64 were benign lesions(13 mucinous cystadenomas, 16 endometriomas, 20 teratomas, 8 serous cystadenomas, and 13 other abnormalities), and 18 were malignant(12 cancers and 6 borderline tumors). The color Doppler scoring system was useful in distinguishing malignant from benign masses, with a sensitivity of 88.2%, compared with the morphological scoring system of 86.7%. The specificity of color Doppler and morphological scoring system were 95.4% and 92.5%, respectively. The sensitivity of combination of both scoring systems was 88.9%, with a specificity of 96.9%. In conclusion, color Doppler scoring system is a useful tool in predicting the malignancy of ovarian lesions especially combined with morphological scoring system.

Appendiceal mucocele is a cystic dilatation of the appendiceal lumen with mucus, which may be caused by either benign or malignant diseases. In this report, five cases of appendiceal mucocele are reported, three of which had a preoperative diagnosis of mucocele, whereas the others were found incidentally during the operation under the diagnosis of intussusception and periappendiceal abscess. All five patients underwent surgical resections, including one ileocecal resection and four right hemicolectomies. Histopathology revealed a mucinous cystadenoma in four cases, and a mucinous cystadenocarcinoma in one. There was no disease-related death during 18 months of follow-up.

PURPOSE: Mucinous cystic neoplasms are at best potentially malignant and present a spectrum of neoplasia ranging from benign neoplasms to invasive carcinoma. The purpose of this study was to investigate the clinicopathologic characteristics relevant to the specific diagnosis of mucinous cystic neoplasms of the pancreas. METHODS: We retrospectively reviewe the clinical features and histopathologic findings of 34 cases who underwent op-erations with mucinous cystic neoplasms of the pancreas from October 1994 to March 2005. RESULTS: There were 25 mucinous cystadenoma (73.5%), 6 mucinous cystic tumor of borderline malignant potential (17.6%), 1 in situ mucinous cystadenocarcinoma (2.9%), 2 invasive mucinous cystadenocarcinoma (5.9%). Their ages ranged from 23 to 76 years with a mean of 44.2. The 88.2% of the patients were women. The 94.1 % of the tumors were located in the body or tail of the pancreas. The tumor size ranged from 2 to 17 cm, especially the mean size of invasive mucinous cystadenocarcinoma was 13.5 cm. The accuracy of CT for diagnosing was 81.8% and that of US was 53.3%. After a follow-up duration from 5 to 103 months, all patients are still alive. However, recurrent disease developed in all of the 2 patients with invasion. CONCLUSION: Our results suggest that complete surgical resection is certainly the gold standard treatment for mucinous cystic neoplasms. A histologic diagnosis of invasive cysta-denocarcinoma portends a dismal prognosis, so close long term follow up is necessary due to tumor recurrence.

Mucocele arised at the vermiform appendix is uncommon, either benign or malignancy and their clinical presentation is not specific. The preoperative diagnosis is rare,1 and their diagnosis is an incidental event. Mucocele seems to be developed due to chronic obstruction of the lumen of the appendix. Higa and Cowerkers2 classified 73 cases of "mucocele" into three clinicopathologic entities; focal or diffuse mucosal hyperplasia, mucinous cystadenoma, mucinous cystadenocarcinoma. Appendiceal mucoceles are rare lesions of the appendix, characterized by a gross enlargement of the appendix from accumulation of mucoid substance within the lumen. It is encountered in only 0.1-0.4% of all appendectomies with a female predominance and an average age at the time of diagnosis over 50 years. A case of appendiceal mucocle found during total hysterectomy is presented with a brief review of the literatures.

This study was performed to assess the significance of plasma level and histochemical character of carcinoembryonic antigen(CEA) in early diagnosis and prognosis of ovarian tumor. Plasma level of CEA was measured using EIA method and immunohistochemical tissue staining of CEA was done using biotin-strepto avidin complex immunoperoxidase technique. The percentage of patients with positive CEA level(above 2.5 ng/ml) was 23.1%(6/26) in malignant ovarian tumor and 15.6%(12/77) in benign ovarian tumor. Positive tissue staining of CEA was 42.3%(11/26) in malignant ovarian tumor and 19.5%(15/77) in benign ovarian tumor. In histologic typing, positive tissue staining of CEA was 18.1%(2/11) in serous cystadenocarcinoma, 85.7%(6/7) in mucinous cystadenocarcinoma, 37.5%(3/8) in other malignant ovarian tumors, 7.1%(1/15) in serous cystadenoma, 7.1%(1/14) in mucinous cystadenoma and 27.1%(13/48) in other benign ovarian tumors. Among 5 cases of malignant ovarian tumors with positive CEA level, 3 cases(60%) showed positive tissue staining of CEA, whereas among 21 cases of malignant ovarian tumors with negative CEA level, 8 cases (38.1%) showed positive tissue staining of CEA. However, among 11 cases of benign ovarian tumors with positive CEA level, 4 cases(36.4%) showed positive tissue staining of CEA, whereas among 66 cases of benign ovarian tumors with negative CEA level, 11 cases(16.7%) showed positive tissue staining of CEA. In the 3 year follow-up study of 12 cases with malignant ovarian tumor, among 3 cases with positive tissue staining of CEA, 2 cases(66.7%) survived. In 9 cases with negative tissue staining of CEA, 6 cases(66.7%) survived. In conclusion, these results suggest that the measurement of tumor CEA may be of value in the differential diagnosis of malignant and benign ovarian tumor, especially in diagnosing mucinous cystadenocarcinoma. However, due to the small amount of cases available for study, it was difficult to determine the correlation between the prognosis and tissue CEA staining of ovarian tumors.

Cystadenoma rarely arises in the parotid gland. It grows slowly without pain. Histopathologically, it is subdivided into papillary cystadenoma and mucinous cystadenoma. Mucinous cystadenoma arising from the salivary gland is a very rare benign tumor. A 25-year-old female patient visited our hospital with a left infra-auricular mass. Computed tomography scan showed a 3.1x2.3 cm size heterogeneous lesion with an irregular margin in the left parotid gland. Sono guided gun biopsy was performed to reveal fibrous tissue with atypical epithelial cell with mucin. Suspecting mucoepidermoid carcinoma, partial parotidectomy was performed for treatment and diagnosis. Histopathologic exam revealed mucinous cystadenoma. Cystadenoma of salivary gland has no distinct clinical feature, and is difficult to differentiate clinically from other salivary gland tumors as well as its malignancy. Thus, the possibility of malignancy must be considered for differential diagnosis.

Primary mucinous cystic cystadenomas of the retroperitoneum are very rarely encountered, and there have been only about 30 cases reported in the literature. The histogenesis of primary mucinous cystadenomas is unclear. Most authors suggested that it develops through mucinous metaplasia in a pre-existing mesothelium-lined cyst. Complete surgical excision is the only treatment and it is required for the final diagnosis and cure. We present here a case report of a 38-year-old Korean woman with primary retroperitoneal cystadenoma. It was a thin-walled, multilocular cyst with a dominant loculus that measured 10.0 X 7.5 X 5.5 cm3 in size, and to the best of our knowledge, this is the first such case to be reported in in Korea.
