The ultrasonographic findings of 49 ovarian cystadenomas were analized. The results were as follows: 1. Themost common age group was 3rd decade and most patients(83%) belong to active reproductive period. 2. In 80% ofserous cystadenoma the size of the tumor was ranged in 6–10cm in diameter. The large tumors of 16–20 cm indiameter were mostly mucinous cystadenomas. 3. Purely cystic appearance was the most common finding(40%) of serouscystadenoma and thick linear septation with and without solid component was the most common finding (38%) ofmucious cystadenoma. 4. Thick linear septation with solid component was not found inserous cystadenoma. 5. Welldefined nodular projection was found in 3 cases of serous cystadenoma but not identified in mucinous cystadenoma.

Serous cystic neoplasm (SCN) of the pancreas is considered a benign tumor with almost no malignant potential. Most surgeons agree that asymptomatic SCN requires only regular observation. However, several complexities and interference with organ preservation during the operation, may develop when a huge symptomatic tumor is treated with surgery. So, the purpose of this study is to develop a potential management plan based on a literature review and by describing three recent cases of SCN of the pancreas. We suggest that SCNs be responded to with a timely and appropriate surgical intervention - before they require clinical attention.

BACKGROUND/AIMS: A macrocystic variant of a serous cystadenoma (M-SCA) is usually indistinguishable from a mucinous cystadenoma (MCA) as a result of their morphologic similarity on conventional imaging studies. However, a MCA requires a resection due to its malignant potential. The aim of this study was to determine the EUS morphological characteristics of a M-SCA to determine if they could be used to help differentiate it from MCA. METHODS: The clinical and EUS morphologic characteristics were examined in 31 consecutive patients with M-SCA and MCA who underwent surgery. RESULTS: Resected specimens were available from 11 M-SCAs and 20 MCAs. Significant differences were observed with regard to the age and location within the pancreas. On EUS, most of the M-SCA contained microcysts (82%) compared with only 15% of MCA cases, and a lobulated configuration of the cyst was observed more frequently in the M-SCA cases than in the MCA (91% vs. 25%). The combination of microcysts and the lobulated configuration of the cysts had a 100% specificity and positive predictive value for differentiating M-SCA from MCA. CONCLUSIONS: M-SCA tends to occur at a relatively younger age than MCA, and is located mainly in the head of the pancreas. Although there is considerable morphological similarity between M-SCA and MCA on the conventional imaging modalities, the morphological characteristics obtained from EUS including microcysts with a lobulated configuration may help to make a distinction between M-SCA and MCA.

Rapid advancements, access to and use of imaging techniques have increased the frequency of identification of pancreatic cystic neoplasms in clinical practice. However, a diagnostic dilemma among pancreatic cystic neoplasms remains. Solid variant serous cystadenoma is extremely rare and difficult to accurately diagnose preoperatively, as they are commonly mistaken for malignant solid tumors of other types. Here, we present a case of a solid variant serous cystadenoma preoperatively misdiagnosed as a neuroendocrine tumor of the pancreas with a review of the relevant literature.

Collision tumor means the coexistence of two adjacent, but histologically distinct tumors without histologic admixture in the same tissue and is rare incidence involving ovary. Because of their incidence of occurrence, benign cystic teratomas often occur coincidentally with other abnormalities of the ovary. Most common histologic combination of collision tumor in the ovary is coexistence of teratoma with mucinous tumors. But its association with serous tumor has been noted rare and incidence is unknown. We have experienced a case laparoscopic treatment of a huge serous cystadenoma combined with ovarian benign cystic teratoma in right ovary, and report it with a brief review of literature.

Ovarian serous tumors of low malignant potential (borderline serous tumors) are intermediate in their clinical behavior between benign serous cystadenoma and malignant neoplasm, and are associated with 10 year survival rates in excess of 90%. Borderline ovarian serous tumors are characterized by absence of stromal invasion but presence of some characteristics of malignancy. Borderline ovarian tumors occur predominantly in premenopausal women, and associated with a very good prognosis. The principal treatment of borderline malignancy is surgical resection of the primary tumor. But approximatley 20% of patients with ovarian tumors of low malignant potential present with Stage III or IV disease at the time of diagnosis. The benefit of postsurgical therapy in this group of patients has not been well established. We report two cases of advanced ovarian serous borderline tumor, one of which was treated with 3 cycles of cisplatin-taxol chemotherpy.

Serous cystadenoma of the pancreas is a benign neoplasm and usually unifocal; multifocal tumors are rare, and to our knowledge, only a few cases have been reported. We describe a case involving two separate serous cystadenomas in the head and body of the pancreas. The patient was a 41-year-old woman with no subjective symptoms. Abdominal ultrasonography performed for the purpose of a routine check-up revealed a septated cystic mass in the body of the pancreas. CBC and blood chemistry revealed no abnormality, but abdominal computed tomography indicated two separate cystic masses with enhanced internal septa in the head and body of the pancreas. Whipple's operation was performed and two serous cystadenomas of the pancreas were diagnosed histopathologically.
