Appendicular Mucocele with Robotic Partial Typhlectomy and Correction of Rectus Abdominal Muscles’ Diastasis: A Case Report

Low-grade appendiceal mucinous neoplasm (LAMN) is rare, and patients are often asymptomatic or have nonspecific symptoms. Appendicectomy should be performed with care and limited handling of the appendix, with extraction of the specimen through an extraction bag to prevent perforation and spillage of mucin, which can result in the development of pseudomyxoma peritonei (PMP). This case report aims to shed light on the approach to appendicular mucocele in contemporary medicine. The reported case shows a presentation of mucocele in a young female patient with symptoms compatible with appendicitis. This case report serves as an example of how to diagnose, manage, and follow-up on appendicular mucocele treatment for colleagues who may encounter similar conditions.

Endoscopic nasal surgery for mucocele and pyogenic mucocele of turbinate: Three case reports

BACKGROUND Cases of turbinate mucocele or pyogenic mucocele are extremely rare.During nasal endoscopy,turbinate hypertrophy can be detected in patients with turbinate or pyogenic mucocele.However,in many instances,differentiating between turbinate hypertrophy and turbinate mucocele is difficult.Radiological examinations,such as computed tomography(CT)or magnetic resonance imaging(MRI),are essential for the accurate diagnosis of turbinate mucocele.Herein,we report three cases of mucocele or pyogenic mucocele of turbinate,including their clinical presentation,imaging findings,and treatments,to help rhinologists understand this condition better.CASE SUMMARY Three cases of turbinate and pyogenic mucocele were encountered in our hospital.In all patients,nasal obstruction and headache were the most common symptoms,and physical examination revealed hypertrophic turbinates.On CT scan,mucocele appeared as non-enhancing,homogeneous,hypodense,well-defined,rounded,and expansile lesions.Meanwhile,MRI clearly illustrated the cystic nature of the lesion on T2 sequences.Two patients with inferior turbinate mucocele underwent mucocele lining removal,while the patient with pyogenic mucocele underwent endoscopic middle turbinate marsupialization.The patients were followed up on the first,third,sixth month,and 1 year after discharge,and no complaints of headache and nasal congestion were reported during this period.CONCLUSION In conclusion,both CT and MRI are helpful in the diagnosis of turbinate or pyogenic mucocele.Additionally,endoscopic nasal surgery is considered to be the most effective treatment method.

Giant appendiceal mucocele: Report of a case and brief review

Mucocele of the appendix is a rare lesion, characterized by distension of the lumen due to accumulation of mucoid substance. This disease is often asymptomatic and pre-operative diagnosis is rare. If untreated, one type of mucocele may rupture producing a potentially fatal entity known as pseudomyxoma peritonei. The type of surgical treatment is related to the dimensions and to histology of the mucocele. Appendectomy is used for simple mucocele or for cystadenoma. Right hemi-colectomy is recommended for cystadenocarcinoma. In this paper, we report a case of a 51-year-old woman with a mobile, painless mass in the right lower quadrant of abdomen caused by a giant appendiceal mucocele. Imaging showed a larger tubular, cystic structure extending below from the inferior wall of the cecum. Surgery revealed a giant retro-cecal appendix measuring 17 cm in length and 4 cm in diameter. The final pathologic diagnosis was mucocele caused by mucinous cystadenoma.

Appendiceal mucocele: Case reports and review of current literature

The mucocele of the appendix is an uncommon disorder which is often asymptomatic but sometimes causes acute appendicitis-like symptoms. Sometimes, patients with mucocele can present with confusing symptoms. Preoperative suspicion and diagnosis of appendiceal mucocele are important. Ultrasonography and computed tomography are useful tools for the diagnosis of appendiceal mucocele. It may be also recognised by colonoscopy as a smooth submucosal lesion of the cecum. Optima management of the mucocele could be achieved through accurate preoperative diagnosis. Preoperative diagnosis is a major component for minimizing intra-operative and post-operative complications. We herein report five cases and discuss the diagnostic methods and surgical treatment.

Mucocele of the appendix: An unusual cause of lower abdominal pain in a patient with ulcerative colitis-. A case report and review of literature

The authors report the case of a 60-year-old male patient. In November 2001 he developed intestinal symptoms of bloody diarrhea and abdominal pain. Colononoscopy and biopsy established the diagnosis of ulcerative colitis (proctosigmoiditis). The disease activity was moderate at the beginning. No significant laboratory alterations were found (including CEA, CA19-9), and mesalazine was started orally. He was in remission until November 2003, when he was admitted to our Outpatient Clinic for upper and right lower abdominal pain and bloody diarrhea. Colonoscopy found proctosigmoiditis with a moderate activity, gastroscopy revealed chronic gastritis, laboratory data was normal. Treatment was amended with mesalazine clysma and methylprednisolone (16 mg) orally. Symptoms ameliorated; however, right lower abdominal pain persisted. US and CT examinat'on demonstrated a pericecal cystic mass (11 cm×3.5 cm). At first pericecal abscess was suspected, as the previous US examination (6 mo earlier) had revealed normal findings. Fine needie aspiration was performed. Cytology confirmed the diagnosis of mucocele. The patientunderwent partial cecum resection and extirpation of the mucocele. He recovered well and the final histology revealed a cystadenoma of the appendix. Follow up was started. The pati雗t is now free of symptoms. Although primary adenocarcinoma of the appendix is uncommon, the authors emphasize that preoperative diagnosis of an underlying malignancy in a mucocele is important for pati雗t management; however, it is difficult on imaging studies.

Retention mucocele of distal viable remnant tip of appendix:An unusually rare late surgical complication following incomplete appendectomy

A 67-year old man was presented with a 6-mo history of recurrent right lower quadrant abdominal pain. On physical examination, a vague mass was palpable in the right lumbar region. His routine laboratory tests were normal. Ultrasonography showed a hypoechoic lesion in the right lumbar region anterior to the right kidney with internal echoes and fluid components. Abdominal contrast-enhanced computed tomography （CECT） showed a well-defined hypodense cystic mass lesion lateral to the ascending colon/caecum, not communicating with the lumen of colon/caecum. After complete open excision of the cystic mass lesion, gross pathologic examination revealed a turgid cystic dilatation of appendiceal remnant filled with the mucinous material. On histopathological examination, mucinous cyst adenoma of appendix was confirmed. We report this rare unusual late complication of mucocele formation in the distal viable appendiceal remnant, which was leftover following incomplete retrograde appendectomy. This unusual complication is not described in the literature and we report it in order to highlight the fact that a high index of clinical and radiological suspicion is essential for the diagnosis of mucocele arising from a distal viable appendiceal remnant in a patient who has already undergone appendectomy presenting with recurrent abdominal pain.

Endoscopic diagnosis and treatment of an appendiceal mucocele:A case report

BACKGROUND Appendiceal mucocele is a rare disease that causes obstructive dilatation of the appendix due to the intraluminal accumulation of mucin.We report a case of endoscopic diagnosis and treatment of an appendiceal mucocele.CASE SUMMARY A 47-year-old man presented with a protrusion around the orifice of the appendix discovered by colonoscopy incidentally.He was admitted to our hospital for a routine checkup without any symptoms.Abdominal computed tomography showed a cystic mass approximately 3 cm in diameter with fat stranding.The preoperative diagnosis was non-neoplastic appendiceal mucocele,and endoscopic treatment was performed.The endoscopic findings and pathological results supported our preoperative diagnosis.The endoscopic treatment of appendiceal mucocele was feasible and effective,which was confirmed by repeated endoscopy and post-operative computed tomography after 7 mo.CONCLUSION Endoscopic therapy provides a new method for the treatment of appendiceal mucocele.

Mucocele of the appendix due to endometriosis:A rare case report

Mucocele of the appendix due to endometriosis is extremely rare,and there are only 10 previously reported cases in the English literature.We report a case of mucocele of the appendix due to endometriosis and provide the first review of the literature.A 43-year-old woman was admitted to the hospital because of recurrent right lower abdominal pain during her menstrual periods.Colonoscopy revealed submucosal tumorlike elevations of the appendiceal orifice.Computed tomography and magnetic resonance imaging of the abdomen suggested cystic lesions near the appendix.Consequently,mucocele of the appendix was suspected preoperatively.An open ileocecal resection was performed.Multiple cystic lesions were observed around the appendix.The cystic lesions contained mucus.Histopathological examination was consistent with a mucocele of the appendix due to endometriosis.The postoperative course was uneventful.We present the first review of the literature to clarify the clinical features.

Laparoscopic appendectomy for appendiceal mucocele in an 83 years old woman

Mucocele of the appendix is an uncommon but potentially dangerous pathological entity that presents in a variety of ways.Therefore,optimal surgical therapy is controversial;while some authors adopt a simple appendectomy,others recommend extensive resection,such as right hemicolectomy.We report the case of an 83 years old woman who presented with cystic neoformation in the right iliac fossa that was preoperatively considered an appendiceal mass.We electively performed a laparoscopic resection that histological examination defined as a mucinous cystadenoma.No recurrence was observed in the follow-up period of 9 mo.

Soft Tissue Recurrence with a Mucocele of an Intraosseous Ameloblastoma

Ameloblastoma is an odontogenic tumor of high frequency and usually occurs as an intraosseous growth. Ameloblastomas frequently recur, sometimes undergoing malignant transformation. These tumors are usually characterized as being multilocular, of the follicular type histopathologically, and invading strongly at the border region of the tumor. More than 10% p53-positive tumor cells give a prognostic indication for a tendency to recur. A recurrent ameloblastoma usually occurs in the intraosseous region near the site of the original lesion. In very rare cases, a recurrent tumor proliferates distantly from the original site in the soft tissue only. We report a rare case of recurrent ameloblastoma in the buccal mucosa with a mucocele that originated from the small salivary glands after the extirpation of an intraosseous (mandibular) ameloblastoma. We also performed a p53 immunohistochemical study of this recurrent tumor.

A Rare Cause of Abdominal Pain: Mucocele of Appendix

The mucocele of appendix or mucosecreting tumor is a rare affection defined as a cystic dilatation of the light of the appendix following the intra luminal accumulation of mucinous, translucent, gelatinous, secretion which may reach either the entire organ or a segment more often distal. The pathogenesisis is discussed;the diagnosis is more often preoperative. The therapeutic depends on the histological nature. This goes from the simple appendicectomy, whose shapes are benign to the right hemicolectomy in the malignant mucocele. We report a case collaged in the general surgical service of the 5th Military Hospital.

Bilateral congenital dacryocystoceles with intranasal mucoceles in the neonate: Case report and review of literature

Congenital dacryocystoceles with intranasal mucoceles are an uncommon entity. The overwhelming majority of reported cases are unilateral in nature. We present a rare case of a neonate with bilateral congenital dacryocystoceles with intranasal mucoceles. Management of dacryocystoceles includes medical and surgical treatment. Literature review revealed 186 reported cases of congenital dacryocystoceles with 82 associated with intranasal mucoceles. Prevalence rates ranged between 11% to 100%. Our case highlights the importance of nasal endoscopy in the work up and identification given the high prevalence rate of intranasal mucocele component in patients with congenital dacryocystoceles.

Mucocele mimicking a gallbladder in a transplanted liver:A case report and review of the literature

Biliary mucoceles after deceased donor liver transplantation are a rarity,and mucoceles mimicking a gallbladder from the recipient remnant cystic duct have not been described until this case.We describe a 48-year-old male who presented with right upper quadrant pain and was found to have a recipient cystic duct mucocele 3 mo after receiving a deceased donor liver transplant.We describe the clinical presentation,laboratory and imaging findings(including the appearance of a gallbladder),multidisciplinary approach and surgical resolution of this mucocele originating from the recipient cystic duct,and a review of the literature.

The Endonasal Endoscopic Management of Paranasal Sinuses Mucoceles

Introduction: Paranasal sinuses mucoceles are benign, epithelial lined, mucus filled lesions, causing destruction of the adjacent sinus walls, and with further gradual extension to adjacent structures, serious morbidities and mortalities may occur. Objective: To emphasize on the efficacy of endonasal endoscopic marsupialization in the treatment of paranasal sinus mucoceles. Method: Retrospective descriptive study on paranasal sinus mucocele cases operated on endoscopically by the author (AAM), in the 10-year-period from to 2009-2019. Result: Total of 23 cases were included, 16 were males and 7 females, age ranging between 14 - 76 years, with a mean age of 45 years Location of mucoceles varied between: Frontal 7 cases (30%), Fronto-ethmoidal 6 cases (26%), Isolated Ethmoidal accounted for 3 cases (13%), sphenoidal 4 cases (17%), maxillary were 3 cases (13%) all of the 23 cases underwent endonasal endoscopic complete marsupialization, none of them required combination with external approach in-spite of different locations and complications, with no recurrence in a mean follow up period of 2.4 years. Conclusion: Endonasal endoscopic approach is a safe, efficient approach in the treatment of most paranasal sinus mucocele case in their different presentations and locations.

Appendicular Mucocele: About a Case Observed in Bamako

It is a globally rare condition that can present in a variety of clinical syndromes or can occur as an incidental surgical finding. It poses the double problem of its possible malignancy and the risk of gelatinous disease of the peritoneum in the event of perforation. We report a case treated in the “A” Surgery Department of the Point-G University Hospital Center (CHU) in Mali in 2022. It was a 62-year-old woman, a housewife who presented to the department. “A” surgery at the Point G University Hospital Center for pain in the iliac fossa. As a medical history, she was hypertensive on atenolol and a known diabetic on diet and metformin-based treatment, as well as symptomatic sickle cell disease (AS) and an undocumented history of peptic ulcer disease. The biological assessments revealed hyperleukocyte with granulocyte predominance. C-reactive protein was positive at 32 mg/l. Ultrasound revealed a 27 mm cystic dilation of the appendicitis in favor of appendicular mucocele. We proceeded with the appendix. The surgical specimen containing gelatinous fluid was removed and histological examination was in favor of a mucinous adenocarcinoma of the appendix.

Mucocele formation of cystic bile duct remnant after orthotopic liver transplantation

Liver transplantation （LT） has become a common ＇method for end-stage liver disease. Although the incidence of biliary complications after LT has decreased to 8% to 20% in recent years, it is still one of the main factors affecting the life quality and long-term survival of recipients. As an uncommon complication, the mucocele formation of cystic duct remnant may compress or obstruct the common hepatic duct and result in injury to the liver graft.
