Repeated Enterocutaneous Fistula in a Munchausen Syndrome Patient

Munchausen syndrome is a rare type of mental disorder in which the patient fakes illness to gain attention and sympathy. Patients may lie about symptoms, make themselves appear sick, or make themselves purposely unwell. We describe a case of repeated enterocutaneous fistula in Munchausen syndrome. A 53-year-old Japanese male was admitted to our hospital for the treatment of a high-flow enterocutaneous fistula. Surgery was performed two times, but the fistula recurred each time. Chopsticks with blood on them were coincidentally detected in the trash in the patient’s room. It was revealed that the enterocutaneous fistula was caused by self-mutilation. A psychiatrist was consulted, and the patient was diagnosed with Munchausen syndrome. The psychiatrist initiated treatment and the patient admitted the self-harm. His prolonged wound site was closed and he was able to be discharged. There has been no recurrence of the self-harm as of this writing, 3 years later. The treatment of Munchausen syndrome is difficult and early detection is important

Report of a case: Retroperitoneal mucinous cystadenocarcinoma with rapid progression

Introduction: Retroperitoneal mucinous cystic neoplasms are uncommon, and little is known about the etiology of the disease. Malignant forms of these are extremely rare. Here, we report a case of primary retroperitoneal mucinous cystadenocarcinoma (PRMC), which demonstrated unexpectedly aggressive progression despite finding only a limited area of adenocarcinoma. Presentation of case: A 62-year-old woman with a complaint of abdominal discomfort was admitted to the hospital. Abdominal CT and MRI showed multiple large retroperitoneal cysts dislocating the right kidney nearly to the center of the abdomen. Transabdominal resection of the cysts was performed. Those cysts contained 1100 ml of mucinous fluids in total. Cytological examination of those fluids revealed no malignant cells. The cyst wall was lined with mucinous epithelial cells, and contained some ovarian-type stroma. Also, there was a focal area of adenocarcinoma in the cyst wall, and the lesion was diagnosed as primary retroperitoneal mucinous cystadenocarcinoma. Eight months later, the patient developed lumbar bone metastasis. Chemotherapy with S-1, an oral fluoropyrimidine, and docetaxel had been begun immediately; however, the disease had rapidly spread in the retroperitoneum. Eventually, the patient died of the disease 15 months after surgery. Discussion: Retroperitoneal mucinous cystic neoplasms are considered to be metaplasia of embryonal coelomic epithelium. Complete excision without rupture is essential. However, variance of biological aggressiveness might exist in PRMCs. Conclusion: Retroperitoneal mucinous cystadenocarcinoma is a rare tumor, and it is urgently necessary to elucidate the etiology of an effective therapy for the disease
