When a bulging appendiceal orifice is observed during surveillance colonoscopy, the possibility of appendiceal mucocele must be considered. Appendiceal mucocele is a rare group of lesions characterized by mucinous distension of the appendiceal lumen with the dangerous potential to rupture, resulting in the development of pseudomyxoma peritonei. Early recognition and diagnosis of appendiceal muc...

BACKGROUND Superficial mucocele presents as small, clear vesicle on noninflamed mucosa. In this study, we report several vesicles on the bucal mucosa of a woman diagnosed as superficial mucocele. CASE PRESENTATION A 48-year old woman presented with multiple vesicles on her labial mucosa, ventral surface of the tongue, floor of the mouth and palate. A mucosal biopsy was taken from the vesicle....

Two young adult males presented with paranasal sinus osteoma associated with mucocele. A 20-year-old man presented with headache and seizure, and another 20-year-old man presented with headache, frontal deformity, and visual disturbances. Both patients underwent surgery and satisfactory results were obtained. Isolated paranasal sinus osteomas are benign and slow-growing tumors, but may become m...

OBJECTIVE To evaluate the necessity of reconstructing the eroded bony boundaries after mucocele marsupialization when the mucoperiosteum has been spared. STUDY DESIGN Retrospective review of 308 patients treated for a sinonasal mucocele. Of these, 116 showed areas of bone reabsorption in their preoperative computed tomography (CT) scan. METHODS Of 116 patients showing one or more areas of b...

The mucous escape reaction or Mucocele as it is called is a salivary gland lesion of traumatic origin which is formed when the main duct of a minor salivary gland is torn with subsequent extravasation of the mucus into the fibrous connective tissue. In due course a cyst like cavity is produced which is filled with mucin. This lesion is described by number of names including mucus retention phen...

Parotid swelling is a common presentation in ENT clinic. Most of the cases involve pathology of the gland. There are not many reported cases about parotid duct pathology. We describe a case of a large parotid duct mucocele with a calculus. Excision of the mucocele and superficial parotidectomy was performed. The post-operative recovery was uneventful.

Mucocele of the appendix is a term used to describe a dilated, mucin-filled appendix. It is most commonly the result of epithelial proliferation, but can be caused by inflammation or obstruction of the appendix. Two cases of mucocele of the appendix are presented with a discussion of the histologic and radiologic features as well as the surgical management.

We report an unusual case of a giant colonic mucocele following ileo-sigmoid bypass surgery in a patient with advanced adenocarcinoma of the splenic flexure. The formation of a giant colonic mucocele resulted from distal splenic flexure obstruction due to tumour relapse and proximal caecal obstruction due to peritoneal disease with subsequent accumulation of mucus in the closed loop.

We have observed two contiguous mucoceles in one patient. Based on the mucoceles' signal intensities on MR imaging, as well as their anatomic location as delineated by CT and MR, we hypothesize that the "downstream" mucocele obstructed the "upstream" sinus, leading to formation of a secondary mucocele.
