Mucinous cystadenoma of the appendix is a type of appendiceal mucocele and a rather rare condition usually found incidentally in the course of other abdominal surgery. A previous evaluation of 73 appendiceal mucoceles showed that this disease was often associated with adenocarcinoma and other epithelial atypia. This observation suggested that patients with mucinous cystadenoma of the appendix a...

Mucocele of the appendix is a descriptive term for an abnormal mucous accumulation distending the appendiceal lumen. Pseudomyxoma peritonei is characterized by mucinous ascites and implants throughout the abdominal cavity. Thirty-four cases of appendiceal mucocele and seven cases of pseudomyxoma peritonei of appendiceal origin on file at the Armed Forces Institute of Pathology were reviewed for...

Mucoceles of the appendix are very rare lesions and are occasionally associated with pseudomyxoma peritonei, a gelatinous ascites that arises from intraperitoneal rupture or degeneration of the mucocele. Rupture of a retroperitoneal mucocele of the appendix is extremely rare; pseudomyxoma extraperitonei has been previously reported in only five patients. We report a new case of pseudomyxoma ext...

The Mucocele or Mucus retention phenomenon is a salivary gland lesion of traumatic origin, formed when the main duct of a minor salivary gland is torn with subsequent extravasation of the mucus into the fibrous connective tissue so that a cyst like cavity is produced. The wall of this cavity is formed by compressed bundles of collagen fibrils and it is filled with mucin. Mucoceles are known to ...

Sphenoid sinus mucocele is an uncommon lesion related to inflammatory disease that is diagnosed after surgery or a traumatic event. This report describes an unusual case revealed by bacterial meningitis and cerebral abscess in a 12-year-old child. CT and MR imaging allowed precise extension to the skull base in preoperative management and follow-up investigations. Endoscopic transnasal marsupia...

A tension mucocele was created in three hepatic homografts by ligating a low-lying cystic duct during transplant cholecystectomy and by incorporating its outflow end into the anastomosis of the common hepatic duct to the recipient common duct or Roux limb of jejunum. The consequent complication of obstruction of the biliary tract that necessitated reoperation and excision of the mucocele in all...

A 79-year-old female was referred to our Gynecologic Department presenting with a pelvic magnetic resonance imaging (MRI), showing an adnexal mass, later confirmed at the pelvic examination. The patient's routine laboratory tests were normal. A sonographic examination was performed with inconclusive results. Although the ultrasonography excluded the presence of vascularization and malignant deg...

Large posterior mediastinal masses may lead threatening complications such as critical tracheobronchial compression. Airway management in these individuals is a challenge and being a lower airway obstruction; rescue strategies are limited. We encountered one such case of a large esophageal mucocele causing extrinsic tracheobronchial compression. We have described the anesthetic management of th...

Colorectal mucoceles usually arise in the appendix, and colonic disease is very rare. We report the first case of a mucocele of the colonic liver flexure that was treated successfully with endoscopy. A 36-year-old man was admitted to our hospital because of abdominal distension persisting for 3 days. Colonoscopic examination revealed a round polyp in the hepatic flexure, and we performed hot sn...
