Mucinous cystic neoplasms of the mesentery: a case report and review of the literature

<p>Abstract</p> <p>Background</p> <p>Mucinous cystic neoplasms arise in the ovary and various extra-ovarian sites. While their pathogenesis remains conjectural, their similarities suggest a common pathway of development. There have been rare reports involving the mesentery as a primary tumour site.</p> <p>Case presentation</p> <p>A cystic mass of uncertain origin was demonstrated radiologically in a 22 year old female with chronic abdominal pain. At laparotomy, the mass was fixed within the colonic mesentery. Histology demonstrated a benign mucinous cystadenoma.</p> <p>Methods and results</p> <p>We review the literature on mucinous cystic neoplasms of the mesentery and report on the pathogenesis, biologic behavior, diagnosis and treatment of similar extra-ovarian tumors. We propose an updated classification of mesenteric cysts and cystic tumors.</p> <p>Conclusion</p> <p>Mucinous cystic neoplasms of the mesentery present almost exclusively in women and must be considered in the differential diagnosis of mesenteric tumors. Only full histological examination of a mucinous cystic neoplasm can exclude a borderline or malignant component. An updated classification of mesenteric cysts and cystic tumors is proposed.</p

Isolated fallopian tube torsion: A rare diagnosis in a perimenopausal patient with adnexal mass and raised Ca 19-9: Endoscopic management and review

Isolated torsion of the fallopian tube in perimenopausal women is very rare. A patient who presented with an adnexal mass with possible ovarian torsion and with a raised Ca 19-9 titer is reported. A 48-year-old perimenopausal woman had acute lower right abdominal pain accompanied by nausea and vomiting. Ultrasonographic studies revealed a multiloculated cystic mass in the right adnexum, and Ca 19-9 was raised. The symptoms worsened, and emergency laparoscopy and salpingoophorectomy were performed. Histology revealed isolated fallopian tube torsion with a benign ovarian cyst. Torsion of the fallopian tube, although rare, should always be considered as part of the differential diagnosis of any symptomatic pelvic mass, even in a perimenopausal woman. Characteristic ultrasonographic and CT findings have been reported, an early diagnosis can be made, and an endoscopic, less radical procedure will be the treatment of choice resulting in shorter hospitalization, increased patient satisfaction, and more cost benefits. © Springer-Verlag 2005
