Primary retroperitoneal mucinous cystadenomas (RMCs) are very rare and their biological behavior and histogenesis remain speculative. An accurate preoperative diagnosis of these tumors is difficult because no effective diagnostic measures have been established. We describe a 29-year-old woman with abdominal pain and a palpable mass. Computed tomography (CT) of the abdomen revealed a retroperi-toneal cystic mass which was resected successfully at laparotomy. Histopathological examination of the resected mass confirmed the diagnosis of RMC. There was no evidence of disease 2 years after surgery.

Goblet cell carcinoid is an uncommon primary tumor of the vermiform appendix, characterized by dual endocrine and glandular differentiation. Whether goblet cell carcinoid represents a morphological variant of appendiceal classical carcinoid or a mucin-producing adenocarcinoma is a matter of conjecture. Rare cases of goblet cell carcinoid with other concomitant appendiceal epithelial neoplasms have been documented. In this report, we describe a rare case of combined appendiceal goblet cell carcinoid and mucinous cystadenoma, and discuss the possible histopathogenesis of this combination.

Appendiceal mucinous cystadenoma （AMC） is an ,uncommon disease. The clinical symptoms arenon-specific, thus the preoperative diagnosis is very difficult. The importance of recognizing this condition lies in preventing spillage during surgery. At present, the widespread use of computed tomography （CT） for evaluating abdominal disease has increased the detection rate and diagnostic accuracy for AMC. Here, we report the CT appearance of 4 histologically proven AMCs.

mucinous cystadenoma is a rare benign tumor. Because it has no specific clinical manifestations or imaging features, preoperative clinical and radiologic diagnoses are difficult to make.l-3 We report here a case of primary mucinous cystadenoma of the terminal ileum wall. In this report, the characteristics of the disease will be discussed and the previous reports in literature on mucinous cystadenoma in other organs will be reviewed.

Hepatobiliary cystadenomas are rare tumors that are difficult to diagnose preoperatively. They can reach large sizes that make them real intraoperative ＂surprises＂. A 63-year-old woman, presented with a symptomatic huge abdominal cystic mass, underwent complete resection of the mass with safety margins. Histopathological report revealed mucinous hepatic cystadenoma with ＂ovarian- like＂ stroma and areas of sclerohyalinization. The differential diagnosis of the large cystic tumors which occupy the right hemiabdomen must include the biliary cystadenoma; the complete resection of the tumor with safety margins avoids local recurrence, and therefore represents the optimal therapy because of the malignant potential of the disease. The postoperative follow-up includes abdominal ultrasound or CT scan and CA 19-9 measurement.

Adnexal torsion is defined by the existence of a partial or complete torsion of the ovary and a tubal portion around its vascular pedicle. It is a rare gynecological emergency. We report the case of adnexal torsion on a large postpartum ovarian cyst in a 40-year-old patient. The diagnosis was suspected based on clinical and ultrasound signs and confirmed by exploratory laparotomy. The appearance of the cyst was suggestive of a mucinous cystadenoma of the ovary. The treatment was radical by performing an adnexectomy. The surgical piece weighed 5.2 kg. The postoperative course was simple. Anatomopathological examination had not been carried out;the parents had buried the operating piece.
