Recurrent Bilateral Mucinous Cystadenoma: Laparoscopic Ovarian Cystectomy with Review of Literature

A Recurrent Mucinous Neoplasm Originating From an Ovarian Mucinous Cystadenoma After an Adnexectomy As the First Procedure: A Case Report

Ovarian mucinous cystadenomas are benign, but they can rarely recur if incompletely excised. We are the very first to report a case of recurrent mucinous neoplasm originating from an ovarian mucinous cystadenoma after adnexectomy as the first procedure. A 58-year-old woman was referred to our hospital with a two-year history of abdominal fullness. Magnetic resonance imaging (MRI) demonstrated a pelvi-abdominal cyst measuring 37 cm, without solid components within the cyst. A laparotomy revealed a huge cystic tumor originating from the right ovary. A right adnexectomy was performed without intraoperative cyst rupture or spillage. Histologically, the cyst was diagnosed as a mucinous cystadenoma. A month after the operation, ultrasonography revealed a cystic lesion measuring 1.8 cm adjacent to the right side of the uterine body. During the follow-up every three months, the cyst enlarged gradually, and an MRI performed 42 months after the operation revealed a cystic mass measuring 5.5 cm, including an internal protrusion. The second laparotomy revealed a cystic mass arising from the right surface of the uterine body, and a total hysterectomy and left adnexectomy were performed. Histologically, this uterine tumor was diagnosed as a mucinous borderline tumor that recurred from the ovarian mucinous cystadenoma. On histological examination of the resected uterus, the silken threads used at the first operation were observed in proximity to the tumor lesion. We speculated that the reason for the recurrence of our case may be the uterine-side remanence of the mucinous tumor cells from the first operation. Because the utero-ovarian ligament became short due to the large ovarian cyst, adnexectomy as a first procedure may be insufficient. A close follow-up of these patients is required for early detection of the recurrence, and attention is necessary for patients having malignant transformation due to an adenoma-borderline-malignant sequence of ovarian mucinous tumors.

Recurrent mucinous neoplasm arising in cesarean scar: A case report and review of literature

Ovarian mucinous tumors are one of the common epithelial tumors in the ovary, but their recurrence is extremely rare. In a 37-year-old female patient who had had five operations in 7 years due to recurrent mucinous neoplasms, a mass extending to the umbilicus was recently detected during a routine examination. With this finding the patient underwent cystectomy, total abdominal hysterectomy, and left salpingo-oophorectomy. Two of the five operations were performed during cesarean delivery. In the recent surgical procedure, two cysts were removed. A 20 cm cyst in the pelvic region was diagnosed as a mucinous cystadenoma. The other cyst located in the myometrium was a mucinous cystadenoma with focal borderline change and arose in the previous cesarean scar. The authors present what is believed to be the first case of recurrent mucinous neoplasm arising within a cesarean scar. A review of the literature concerning the topic is also presented.

Primary peritoneal mucinous cystadenocarcinoma mimicking possible recurrent ovarian mucinous cystadenoma: coincidental pathology or a spectrum of disease?

We present the case of a 32-year-old woman with a previous surgical history of benign mucinous cystadenoma resected in 2012 who underwent magnetic resonance cholangiopancreatography following her second pregnancy in 2020. This demonstrated a large cystic mass in the left subdiaphragmatic space. Histopathology confirmed a well-differentiated primary peritoneal mucinous cystadenocarcinoma displaying cells of a Mullerian origin. We subsequently discuss the aetiology of these conditions separately and explore the possibility of a connection between the two regarding origin or potential malignant transformation that may otherwise have occurred coincidentally in this young patient. We also acknowledge a paucity of evidence regarding subsequent management strategies.

A case of ovarian mucinous cystadenoma in a child that recurred 1 year after surgery

Introduction and importance

In children, mature cystic teratomas are the most common ovarian tumors. Mucinous cystadenomas are rarely seen. Further, the recurrence of mucinous cystadenomas is very rare. This report describes a case of ovarian mucous cystadenoma in an adolescent that recurred 1 year after surgery.

Case presentation

A 13-year-old patient, with a sizable ovarian tumor underwent laparoscopic-assisted cystectomy. On histopathology, the tumor was diagnosed to be an ovarian mucinous cystadenoma. The mucinous cystadenoma recurred 13 months after surgery and subsequently laparoscopic right adnexectomy was performed.

Clinical discussion

It has been reported that intraoperative cyst rupture and cystectomy instead of adnexectomy are risk factors for mucinous cystadenoma recurrence. Close follow-up is required for post-cystectomy patients because of the possibility of recurrence.

Conclusion

The risk of recurrence and the preservation of fertility should be carefully considered when deciding on treatment in young patients with a mucinous cystadenoma.

•

Mucinous cystadenomas are uncommon in children and their recurrence is very rare.

•

Patients undergoing cystectomy should be carefully followed up for recurrence.

•

The risk of recurrence is a key factor when deciding on treatment.

•

The preservation of fertility should be considered when treating younger patients.
