Case 300: Ruptured MucinousCystadenoma of the Pancreas. History Part one of this case appeared 4 months previously and may contain larger images. A 40-year-old woman presented to the outpatient department of our hospital with a 2-year history of abdominal pain, which had worsened in the past few days. There were no other constitutional symptoms; in particular, there was no weight loss or loss
Differential diagnosis of pancreatic serous cystadenoma and mucinouscystadenoma: utility of textural features in combination with morphological characteristics. Texture analysis of medical images has been reported to be a reliable method for differential diagnosis of neoplasms. This study was to investigate the performance of textural features and the combined performance of textural features and morphological characteristics in the differential diagnosis of pancreatic serous and mucinouscystadenomas. We retrospectively reviewed 59 patients with pancreatic serous cystadenoma and 32 patients with pancreatic mucinouscystadenoma at our hospital. A three-dimensional region of interest (ROI) around the margin of the lesion was drawn manually in the CT images of each patient, and textural parameters were
Discrimination of Pancreatic Serous Cystadenomas From MucinousCystadenomas With CT Textural Features: Based on Machine Learning. This study was designed to estimate the performance of textural features derived from contrast-enhanced CT in the differential diagnosis of pancreatic serous cystadenomas and pancreatic mucinouscystadenomas. Fifty-three patients with pancreatic serous cystadenoma and 25 patients with pancreatic mucinouscystadenoma were included. Textural parameters of the pancreatic neoplasms were extracted using the LIFEx software, and were analyzed using random forest and Least Absolute Shrinkage and Selection Operator (LASSO) methods. Patients were randomly divided into training and validation sets with a ratio of 4:1; random forest method was adopted to constructed
Mucinous cystadenocarcinoma arising from mucinouscystadenoma of the lung: case report and review of the literature Mucinouscystadenoma is a benign tumor commonly found in the pancreas, the ovaries or the appendix. Only very few cases of these tumors originating from the lungs have been reported worldwide, with even less cases describing malignant transformation. We present the case of a 58-year -old woman with a history of recurrent pulmonary infections who underwent left upper lobectomy for lung abscess and was initially diagnosed with pulmonary mucinouscystadenoma (PMCA). Upon thorough immunohistochemical workup, especially due to carcinoembryonic antigen (CEA) positivity, intramucinous singlet cells were eventually diagnostic for invasive carcinoma, in this case a mucinous
A rare case of giant extra-ovarian mucinouscystadenoma arising from sigmoid mesocolon An 80-year-old female presented with one month history of acutely worsening abdominal distention and pain, without features of bowel obstruction. A giant intra-abdominal simple cyst, separate from the ovaries, was seen on imaging. Initial haematological and biochemical investigations, including tumour markers , were normal. At laparotomy, the cystic tumour was discovered to arise from the sigmoid mesocolon and was resected . Histopathology revealed the tumour to be a benign extra-ovarian mucinouscystadenoma, which is a neoplasm of ovarian origin that can arise from extra-ovarian sites, including the mesentery. Extra-ovarian mucinouscystadenoma arising specifically from the mesentery are very rare intra
Ovarian MucinousCystadenoma After Ovarian Graft. Freezing strips of ovarian cortex before chemotherapy followed by transplantation is an experimental method to preserve fertility for reproductive-aged women with cancer. We report a case of a cancer patient who developed a mucinouscystadenoma in a grafted piece of ovarian cortex. A 32-year-old woman with a Ewing sarcoma had ovarian to be a mucinouscystadenoma. Ovarian pathology can develop in previously frozen ovarian cortex tissue after transplantation back onto the ovary. This suggests that routine gynecologic surveillance remains important for these women.
Urachal borderline mucinouscystadenoma: A rare case report and literature review. Urachal borderline mucinouscystadenoma is very rare and has only 9 cases in the current literature with the biological behavior between adenoma and adenocarcinoma. We reported a 41-year-old man with moderate lower abdominal pain, and the imaging examination found an irregular cystic lesion extending from umbilicus to the dome of urinary bladder with significant separations and calcifications. The diagnosis was confirmed according to the specific anatomical location and pathological examination which was proved as mucinouscystadenoma with low malignant potential. The patient undertook radical excision and partial cystectomy. His postoperative condition was good. Urachal borderline mucinouscystadenoma can
Mechanical intestinal obstruction secondary to appendiceal mucinouscystadenoma: A case report and brief review. Appendiceal mucinouscystadenoma can present in various ways, and it is most commonly encountered incidentally during appendectomy, but mechanical intestinal obstruction secondary to an appendiceal mucocele has been rarely reported. We report a case of mechanical intestinal obstruction secondary to appendiceal mucinouscystadenoma. After nasogastric decompression and initial aggressive intravenous fluid resuscitation, an emergency operation was performed under the diagnosis of acute mechanical intestinal obstruction. We performed an appendectomy and intraoperative enteral decompression without anastomoses. The pathologic examination (PE) revealed appendiceal mucinous
Preoperative Diagnosis and Surgical Approach of Appendiceal MucinousCystadenoma: Usefulness of Volcano Sign We report a case of appendiceal mucinouscystadenoma that was successfully diagnosed preoperatively and treated by laparoscopic resection. We could find volcano sign on colonoscopy and cystic lesion without any nodules at the appendix on computed tomography (CT). Without any malignant
Primary retroperitoneal mucinouscystadenomaMucinouscystadenomas and carcinomas of the ovary are well-established and common tumors. However, Primary retroperitoneal mucinouscystadenomas (PRMCs) are very rare. We present a 50-year-old woman referred to our institution with history of intermittent abdominal pain and palpable mass in her left flank. On CT-scan an unilocular cystic mass with thin
MucinousCystadenoma: A Rare Hepatic Tumor in a Child Mucinouscystadenomas (MCAs) of the liver (also called hepatic biliary cystadenomas) are rare tumors that comprise about 5% of cystic masses of the liver in adults. These slow-growing lesions most commonly occur in middle-aged individuals, with a female sex predominance. Herein, we present a MCA in a 6-year-old male, one of only very few
Discrimination of serous cystadenoma from mucinouscystadenoma in the pancreas with contrast-enhanced ultrasonography: a prospective study in 61 patients The preoperative diagnosis between serous cystadenomas (SCAs) and mucinouscystadenomas (MCAs) in pancreas is significant due to their completely different biological behaviors. The purpose of our study was to examine and compare detailed
MucinousCystadenoma of the Testis: A Case Report with Immunohistochemical Findings Mucinouscystadenoma of the testis is a very rare tumor. Herein, we report a case of mucinouscystadenoma arising in the testis of a 61-year-old man, along with a literature review. Computed tomography showed a 2.5-cm-sized poorly enhancing cystic mass. Grossly, the tumor was a unilocular cystic mass filled with mucinous material and confined to the testicular parenchyma. Histologically, the cyst had a fibrotic wall lined by mucinous columnar epithelium without atypia. Immunohistochemical staining was positive for cytokeratin 20 and CDX2, as well as focally positive for cytokeratin 7. The pathologic diagnosis was mucinouscystadenoma.
Laparoscopic Anatomical Left Hepatectomy for Intrahepatic Bile Duct Papillary MucinousCystadenoma With Intraoperative Vascular Repair: A Case Report. Laparoscopic hepatectomy has been widely performed for patients with benign liver tumors such as hepatic hemangioma, focal nodular hyperplasia, and hepatic adenoma.We here present a case of a 78-year-old female patient who was initially admitted on the 6th day after surgery. Postoperative pathological diagnosis was intrahepatic bile duct papillary mucinouscystadenoma.
A huge ovarian mucinouscystadenoma causing virilization, preterm labor, and persistent supine hypotensive syndrome during pregnancy Mucinouscystadenoma (MC) of the ovary is an unilateral, multilocular cystic benign epithelial tumor. Supposed to be hormone responsive, MC reaches huge sizes during pregnancy. Aortocaval compression is common during pregnancy, especially when the pregnant woman is in the supine position. However, the compression recovers with a change in position. The authors report the first case of a huge mucinouscystadenoma of the ovary complicating pregnancy and causing virilization, premature labor, and persistent supine hypotensive syndrome.
Retroperitoneal mucinouscystadenoma of the appendix mimicking hydatid cyst: A case report Appendiceal mucocele is a cystic dilatation of the appendix due to abnormal appendiceal mucinous secretion. Cystadenoma of the appendix is one of the most common causes and is encountered in 0.6% of all appendectomy specimens. The diagnosis may be difficult due to the asymptomatic nature of the disease ; pain in the right lower quadrant may be the only symptom. Complex ovarian cyst, urolithiasis or cystic hydatid disease of the liver have been reported as mimicking appendiceal mucocele in the literature. In this study, we present a case of mucinouscystadenoma of the appendix mimicking retroperitoneal hydatid cyst in a 59-year-old woman. The patient was treated with laparoscopic appendectomy
Giant Appendicular Mucocele Due to MucinousCystadenoma Mucocele of the appendix is a rare clinicopathological entity simulating acute appendicitis. The most common form of the mucocele is cystadenoma, which is characterized by luminal dilatation producing large amounts of mucin. We present a new case of a giant mucocele of appendix with mucinouscystadenoma. A 61-year-old female was admitted to be a mucocele with mucinouscystadenoma with negative surgical margins. The patient was discharged postoperative 6th day, and a control colonoscopy and abdominal CT was planned for 6 months following surgery. Appendicular mucocele is rare and difficult to diagnose preoperatively, and sometimes it may be of large size which increases the risk of perforation. Pseudomyxoma peritonei (PP) is the most feared
Mucinouscystadenoma of the appendix presenting as an umbilical hernia: A case report Mucinouscystadenoma of the appendix is a rare condition that develops as a result of proliferation of mucin-secreting cells in an occluded appendix. Mucinouscystadenoma of the appendix presenting as an umbilical hernia is a rare clinical entity. The most common causes of this condition are known to be ascites , hepatitis and cirrhosis; however, the patient in the present study, was diagnosed as hepatitis- and cirrhosis-negative, with no history of chronic coughing or constipation. The aim of the present study was to report a rare case of mucinouscystadenoma of the appendix presenting as an umbilical hernia in a 66-year-old female patient. The patient had a 6-month history of a reducible mass in the umbilical
