Management of mucoid cysts of the oral cavity: Cases series and review

INTRODUCTION

A mucoid cyst is a benign lesion in the oral mucosa resulting from the rupture of a salivary gland duct and the subsequent discharge of mucin into the soft tissues. Mucoceles are more common in children and young adults, and the most common site is the lower inner lips.

CASES SERIES PRESENTATION

We describe 3 clinical cases managed in service between 2022 and 2023. Clinical cases are presented in order to detail their clinical history, paraclinical and treatment.

DISCUSSION AND CONCLUSION

In general, mucoceles tend to resolve spontaneously, but can sometimes interfere with swallowing or speech. Therefore, in such cases, these lesions must be promptly diagnosed and treated. There are various methods of managing these lesions, each with its own advantages and disadvantages. Surgical technique is preferable when the lesion is persistent, recurrent or symptomatic, and remains the most effective strategy, despite the existence of other, more modern techniques that are better tolerated by patients. But in all cases, follow-up is very important, especially when the mucocele is located in a particular area, such as the ventral side of the tongue, or in a younger population.

A giant peripheral ossifying fibroma of the mandible: A rare case report

INTRODUCTION

Peripheral ossifying fibroma (POF) is an unusual localized, reactive benign gingival growth. POF is usually small in size, it's measure <2 cm in diameter, but rarely reaches important sizes. The aim of this work was to present a rare case report of a giant peripheral ossifying fibroma of the mandible measuring >2 cm in diameter, misdiagnosed as peripheral myxoma.

CASE PRESENTATION

We present the case of a 42-year-old woman with a large peripheral ossifying fibroma in the oral cavity measuring 6 × 4 cm in diameter. The patient presented with an asymptomatic, slowly growing gingival mass in the left anterior and posterior region of the mandible. It gradually increased in size for more than two years. The patient had a mild mental deficit; however, we performed biopsy surgery, which revealed a peripheral myxoma, and then treated the tumor by excision under local anesthesia. The final histopathological examination revealed a peripheral ossifying fibroma.

CLINICAL DISCUSSION

This case report shows that POF can grow and reach unusual dimensions that may contribute to occlusal problems. The diagnosis of POF is based on clinical and radiographic features. The histopathological examination of the biopsy specimen can misdiagnose the lesion; therefore, the final diagnosis is based on the histopathological examination of the complete excised lesion.

CONCLUSION

POF is usually small, but can reach a larger size. The histopathological examination of the entire lesion is of paramount importance to make a final diagnosis.

Brown tumor of the jaw as a rare manifestation of hyperparathyroidism: Two case reports and literature review

INTRODUCTION AND IMPORTANCE

Brown tumor is a giant cell focal lesion of bone associated with hyperparathyroidism, even primary or secondary. Differential diagnosis of these lesions from others giant cell lesions of the jaw bone is mandatory for the correct treatment of the patient.

CASE PRESENTATION

We present here two cases of brown tumor affecting the jaws by describing their clinical aspects and radiographic features, diagnostic criteria and treatment of this disease.

CLINICAL DISCUSSION

Brown tumor is one of the lesions that develop in patients with hyperparathyroidism or renal failure. Skeletal bones including maxillo-facial ones can be the site of this lesion, also radiographic and histopathological exams of the jaw lesion are not sufficient to determine the diagnosis, which requires laboratory tests and radiographic examination.

CONCLUSION

Dental surgeon should be aware of oral manifestations associated with systemic diseases, hence the importance of careful physical examination and thorough investigation for the diagnosis and treatment success. This article aims to illustrate the management strategy to aid clinicians in suspected cases of brown tumor.

Traumatic ulcer of the tongue mimicking a malignant lesion: Case report

INTRODUCTION AND IMPORTANCE

The most prevalent oral ulcers are those caused by trauma, and their etiopathogenesis has been frequently obvious. Yet, oral ulcers can be misdiagnosed and managed incorrectly.

CASE PRESENTATION

A 25-year-old patient presented to our service with a painful lesion on the right lateral border of the tongue that had evolved for one week. A possible traumatic factor was identified. The ulcer completely recovered once the trauma's cause was removed. An accurate diagnosis was achieved by combining a precise physical examination with clinical follow-up.

CLINICAL DISCUSSION

Single oral ulcers have various clinical presentations that can be confusing. Some of them may mimic oral squamous cell carcinoma (OSCC), especially when accompanied by any induration. Determining the cause of oral ulceration requires a careful medical history and a clinical examination with inspection and palpation, which may be combined with other accessory investigations if necessary.

CONCLUSION

This clinical case reinforces the importance of investigating local causes before moving on to systemic ones. We present differential diagnosis and management algorithm of single oral ulcers.

Retrospective cross-sectional study of 34 cases of pernicious anemia at Mohammed V Military Training Hospital, Morocco

Introduction

pernicious anemia is an autoimmune disease characterized by atrophic gastritis due to malabsorption of vitamin B12. Certain oral manifestations, such as Hunter´s glossitis and burning mouth syndrome, may precede the onset of this anemia. The aim of this study is to describe the clinical presentation, para-clinical aspects, the treatment, and the evolution of the pernicious anemia (PA) after treatment.

Methods

retrospective study conducted at the Department of Haematology and Internal Medicine B of the Mohammed V Military Training Hospital in Rabat between January 2009 and December 2018. Thirty-four patients were enrolled with vitamin B12 deficiency, non-regenerative macrocytic anemia, a positive anti-intrinsic factor antibody and anti-parietal cell antibody and a histological diagnosis of atrophic gastritis in the presence or not of Helicobacter pylori. The qualitative variables were expressed in numbers and percentages, and the quantitative variables in mean and standard deviation. Multivariate analysis used the Fischer test; it was considered significant for a p < 0.05 value.

Results

thirty-four cases were studied; the population study consists of 56% (n=19) of men and 44% (n=15) of women. The average age was 54.88± 9.14. The clinical manifestations of pernicious anemia are dominated by megaloblastic anemia 85.3% (n=29), followed by digestive 58.8%(n=20) and oral 55.9% (n=19) signs. Neurological manifestations were rarely found in 41% (n=14). Hunter´s glossitis 37% (n=7), stomatodynia 11% (n=2) were the most common oral manifestations accompanying pernicious anemia. The evolution was favorable in 79.4% (n=27) patients under substitution therapy with vitamin B12.

Conclusion

dentists´ involvement in the diagnosis of pernicious anemia is based on changes in oral mucous membranes, which have been reported in 55.9% of all patients. These oral changes may occur in the absence of symptomatic anemia.

Numb chin syndrome revealing a mandibular metastasis: Case report

INTRODUCTION AND IMPORTANCE

Numb chin syndrome (NCS), although rare, is an important clinical finding. It may be a metastatic neurologic manifestation of malignancy, often with no clinically visible pathologic finding.

CASE PRESENTATION

A 40-year-old female, with prior history of breast cancer, presented to our service with complaint of pain and left mandibular hypoesthesia for four months. Panoramic showed several irregular osteolytic lesions of the mandibular body. CT-scan images showed a large irregular hypodense lesion and a tissue infiltration of the left mandibular body blowing the buccal cortex. Histopathology showed a neoplastic proliferation of carcinomatous cells positive for the cytokeratin AE1/AE3. A diagnosis of breast carcinoma mandibular metastasis was made. The patient was referred sent to the oncology committee. She was treated with Palbociclib and hormone therapy.

CLINICAL DISCUSSION

In the oral cavity, the mandible is the most common site for metastasis. Metastatic tumors of the oral cavity may be asymptomatic or present different non-pathognomonic. Numb chin syndrome which is considered as an important presentation of oral metastases. The consideration of malignancy as a differential diagnosis may help in early diagnosis and intervention that may affect disease prognosis.

CONCLUSION

Dentists and other oral health care providers must be aware of this condition to consider metastatic cancer in patients with unexplained facial hypoesthesia.

Recessive dystrophic epidermolysis bullosa (RDEB): Oral manifestation and management rules in oral surgery: A case report

INTRODUCTION AND IMPORTANCE

The recessive dystrophic epidermolysis bullosa is a severe form of hereditary epidermolysis bullosa characterized by deformities of the skin, blisters and erosions on the mucous membranes. Oral manifestations are frequent and extensive vary from small discrete vesicles to large bullae, associated with microstomia, ankyloglossia and a depapilled tongue. The purpose of this case report is to describe oral health status of patient with recessive-dystrophic epidermolysis bullosa, and the measures that dentists should adopt with the purpose of provide an effective dental treatment.

CASE PRESENTATION

We present a clinical case of a patient with recessive-dystrophic epidermolysis bullosa who underwent a bone regularization and whose follow-up was carried out until healing.

CLINICAL DISCUSSION

The management of patients with RDEB in oral surgery requires the adoption of an atraumatic technique and certain precautions to limit the formation of bullae and promote mucosal healing.

CONCLUSION

We can conclude that oral management of patients with recessive dystrophic epidermolysis bullosa presents a challenge for the oral surgeon and the management is generally multidisciplinary and relies essentially on the adoption of a preventive and atraumatic approach.

Late dental effects in children submitted to chemotherapy: A case report

Chemotherapy may have many effects on teeth such a microdontia, hypoplasia and V shaped roots. The incidence and severity of dental abnormalities depend on the age at the diagnosis, the type of chemotherapeutic agent used. Therefore, it is important that general and pediatric dentists be aware of the late adverse effects of cancer therapy in children, especially in the oral cavity. This article intends to document a case illustrating different dental anomalies secondary to chemotherapy in 20 years old boy who had a history of chemotherapy in childhood.

Diagnosis and Management of oro-antral fistula: Case series and review

INTRODUCTION AND IMPORTANCE

The oro-antral communication (OAC) is a pathological opening between the maxillary sinus and the oral cavity. When it does not close spontaneously or if it is not treated, it remains permeable and epithelializes to develop into an oro-antral fistula (OAF) and can cause maxillary sinusitis.

CASES PRESENTATION

The authors present through 5 clinical cases the different steps of the surgical protocols opting for the buccal fat pad flap and the advanced buccal flap to treat OAF/OAC.

CLINICAL DISCUSSION

Surgical closure of the OAC within 48 h is recommended to avoid complications. Several alternative techniques have been described over the years for the management of the OAC and OAF, with their advantages and limitations. The most commonly used surgical flaps are of two types: the advanced buccal flap and the buccal fat pad (BFP) flap.

CONCLUSION

The adequate availability of the advanced buccal flap and the buccal fat pad (BFP) flap in the majority of patients, the easy handling, the minimal donor site morbidity as well as the excellent blood supply make them perfect flaps for the closure of OAF/OAC. However, follow-up remains a key point and very important to avoid complications. The present case series was limited by the small number of patients and the authors recommend a study with larger groups.

An unusual intraoral lipoma: case report and review of the literature

Lipoma is a common tumor of soft tissue with rare occurrence in oral cavity accounting for only 1-4% of benign oral tumours. It may be noticed only during routine dental examinations. Most of them rarely cause pain, resulting in delay to seek treatment. Lipoma of the oral cavity may occur in any region. The buccal mucosa, tongue, and floor of the mouth are among the common locations. A case of large intraoral lipoma occurring in mental region in a 60-year-old female patient is reported. It was treated surgically under local anesthesia, and 6 month follow up showed excellent healing without any recurrence.

Management of oroantral fistula with displacement of the root into sinus using buccal fat pad: a case report

Oroantral fistula (OAF) refers to a permanent connection between oral cavity and maxillary sinus. The extraction of maxillary posterior teeth is the most common reason of OAF. Multiple techniques are available to repair this defect. The most used procedures involving local flaps include buccal flap, buccal fat pad (BFP), and palatal rotating flap. We here present an original technique of management of oroantral fistula with displacement of the root into sinus using BFP.

Esthetic improvement of a cutaneous sinus tract of odontogenic origin

A cutaneous sinus tract of dental origin is relatively uncommon and may easily be misdiagnosed because of its unusual occurrence and absence of dental symptoms. Extraoral drainage depends on the location of the affected tooth as well as on specific factors such as the virulence of the microorganism, resistance of the patient's body, and the relationship between anatomy and muscle facial attachments.

[Mucocele of the oral mucous membrane]

Les mucocèles buccales sont des pathologies tumorales bénignes des glandes salivaires accessoires de la muqueuse buccale. La localisation la plus fréquente de ces lésions est la muqueuse labiale. Etiologiquement, elles sont de deux types: le premier est dû à une rupture de l’épithélium de la glande déversant de la salive dans l’espace extra-glandulaire, et forment un pseudo kyste (mucocèle par extravasation); le second est causé par blocage de l’évacuation salivaire par prolifération épithéliale du conduit excréteur, réalisant un vrai kyste salivaire (kyste de rétention). Il existe diverses modalités thérapeutiques, l’exérèse chirurgicale conventionnelle reste la stratégie la plus efficace où la récidive est la moins fréquente. A travers une observation clinique, une mise au point sur cette lésion est faite, illustrée par un cas clinique pris en charge dans le Service d’Odontologie Chirurgicale, Centre de Consultation et de Traitement Dentaire (CCTD), Rabat, Maroc.

Oral disorders related to acromegaly

Acromegaly is a rare disease caused due to hyper secretion of growth hormone. Most of the cases of acromegaly are caused by pituitary adenoma which can be microadenoma or macroadenomas. This condition has a tendency toward overgrowth of the mandible, maxillary widening, tooth separation and skeletal malocclusion which compromises the aesthetics of an individual. Hence dentists have a role in diagnosing this disorder. The aim of this paper is to present a case report of acromegaly.

Low laser therapy as an effective treatment of recurrent aphtous ulcers: a clinical case reporting two locations

Apthous ulcers, commonly referred to as canker sores, are the most common ulcerative lesions of the oral mucosa. These are usually painful and are associated with redness and occasional bleeding from the affected area(s). Low Level Laser Therapy (LLLT) has shown excellent results in relieving the pain and complete remission of the oral ulcers. Through a clinical case, we report two locations of oral ulcers treated successfully with diode laser.

The Efficacy of Low-Level Laser Therapy in Treating Oral Papilloma: A Case Reporting A Lingual Location

Oral papilloma is a benign proliferation of the stratified epithelium, which results in a papillary or verrucous exophytic mass, which can be induced by human papillomavirus. These oral mucosa lesions are most often asymptomatic and have small progression. Laser-assisted surgery is common nowadays with several advantages including successful hemostasis, devoid of sutures, wound sterilization and minimal postoperative pain, and edema. The aim of this report is to present the oral papilloma in a 40-year-old female patient and its treatment with soft-tissue laser. The lesion was excised with diode laser, and the healing was uneventful in a follow-up visit after 1 month. Oral papillomas can be found in young adult patient's oral cavity, and laser dentistry can be used by dental clinicians to treat these kinds of oral lesions and should be considered as an alternative to conventional surgery.

Giant Complex Odontoma of Mandible: A Spectacular Case Report

INTRODUCTION

Odontomas are considered as benign tumors of odontogenic tissue origin and are more over non-aggressive. They can also be categorized as hamartomas and are a result of developmental malformation of odontogenic tissues. As the name suggests, they are composed of mature tooth substances. They possess limited and slow growth potential and are well differentiated. They can be ectodermal, mesodermal or mixed in origin. Mixed variety may be further divided into compound or complex depending upon their radio-graphical resemblance to the tooth. Compound odontomes are reported to be twice more common than complex odontomes. Among them, complex odontomes are asymptomatic unless they cause bony expansion of the jaws.

CASE REPORT

This paper aims to report and discuss a case of complex odontoma with unusually large size leading to gross facial asymmetry. Further this paper will highlight the important information the general dental practitioner must possess to diagnose such lesions at an early stage.

CONCLUSION

Odontomas are benign odontogenic tumors with unusually large size leading to gross facial asymmetry. The general dental practitioners must possess the knowledge and important information to diagnose such lesions at an early stage.

[Enlargement of mandibular canal and lower lip hypoesthesia revealing non-Hodgkin’s lymphoma of the mandible]

INTRODUCTION

Primary lymphoma of the mandible are rare and most often revealed by painless swelling. They are often confused with odontogenic lesions. Hence, their diagnosis is delayed. The authors report the case of an isolated mandibular lymphoma revealed by hypoesthesia of the lower lip and enlargement of the left mandibular canal.

CASE REPORT

A 35-year-old woman patient consulted for hemi-mandibular pain with episodes of left labial hypoesthesia. Clinically, we noted the presence of a vestibular tumor in front of tooth 34. A panoramic radiograph revealed that the left mandibular canal was widely enlarged, extending from the mandibular foramen to the mental foramen. The biopsy revealed a B-cell lymphoma. No other localization was found. After treatment with seven courses of a chemotherapy based on R-CHOP followed by local radiotherapy, the patient was in remission eighteen months after treatment.

DISCUSSION

Primitive lymphoma of the mandible are rare; they represent about 0.6% of extra-nodal non-Hodgkin lymphoma. They occur at any age and mainly affect males. They most often come out as a painless swelling, sometimes ulcerated in the mouth. They are often misdiagnosed as a dental problem. Treatment combines variably radiotherapy and/or chemotherapy. The prognosis of bone lymphoma is more favorable than others malignancies bone, with a survival rate of 40-50% at five years.

[Prevalence and clinical characteristics of oral bony outgrowth in a Moroccan population]

OBJECTIVES

Oral bony outgrowths (OBOs) are localized bony protuberances that arise from the cortical plate. Various types of OBOs have been described, the precise designation of which depends on anatomic location such as torus palatinus, torus mandibularis, buccal exostosis, or palatal exostosis. We had for aim to determine the prevalence and clinical characteristics of OBOs in a Moroccan population.

METHODS

This cross-sectional study was conducted between March 15 and June 30, 2011 at the Rabat-Salé teaching hospital dental consultation and treatment center, in Morocco. Three hundred and fifty-three patients (160 female and 193 male patients), 11 to 82 years of age, were examined clinically and radiologically to determine the presence of OBO.

RESULTS

Twenty-four patients (6.8%) presented with OBOs. The prevalence for exostosis, torus mandibularis, torus palatinus, and associated OBOs was 3.1%, 2%, 0.8%, and 0.9% respectively. There was a significant difference (P=0,01) between the average age for patients presenting with OBO (43.2±12 years of age) and the average age for patients without any OBO (36.5±16 years of age). The prevalence of OBOs in female patients (7.3%) was higher than in male patients (6.3%) but the difference was not significant (P=0.439). Patients with occlusal parafunctional activity presented with significantly more OBO (P=0.016).

DISCUSSION

The reported prevalence of OBO is extremely variable, according to age, gender, and ethnic group. The occurrence of OBO could be triggered by genetic factors associated with environmental factors.

[Alveolitis: review of the literature]

Alveolitis are infectious complications following the dental extraction. They appear under two forms: dry, characterized by a painful syndrome and uninhabited alveolus, and suppurative, which becomes identified by provoked pain and alveolus filled. Their etiopathogenesis remain a subject of interrogation because of the rarity of studies concerning this complication. Nevertheless, treatment is mainly favorable by a sedation of the pain and the startup of a physiological healing. From this article, we are going to review their clinical forms, their etiology as well as the followed treatment.

[Botryoid odontogenic cyst]

INTRODUCTION

The botryoid odontogenic cyst (BOC) is a developmental cyst of odontogenic epithelial origin considered as a rare multilocular variety of lateral periodontal cyst (WHO 1992). This cystic lesion site is in the periodontal space of vital teeth.

OBSERVATION

A 21-year-old woman consulted for a swelling of the anterior maxillary region. The clinical examination revealed bucal swelling extending from the left central incisor to the first left premolar. The mucosa was normal. The adjacent teeth were vital. X-ray revealed a bilocular radiolucency extending between the roots of teeth 21 and 24. The lesion was enucleated, under local anaesthesia via a vestibular approach. Histology was typical of a BOC with cystic spaces lined by squamous epithelium with thickening and clear cells. Forty-eight months after surgery, there was sign of recurrence.

DISCUSSION

BOC is known to be a recurrent odontogenic cyst. Several cases of multiple recurrences have been reported up to nine years after the initial surgery. Long-term follow-up is thus mandatory.

[Odontogenic myxoma of the maxillary]

INTRODUCTION

Odontogenic myxoma is a rare benign tumor that arises from the mesenchymal portion of the tooth germ. It has a va-riable non-specific clinical and radiological appearance, and may be confused with other lesions such as ameloblastoma.

CASE REPORT

We describe the case of a young, African male patient with a large odontogenic myxoma of the maxillary. The patient presented a painless firm swelling of the left maxillary. The radiograph showed a radiolucent lesion that was compatible with several diagnoses.

DISCUSSION

The diagnosis was based on clinical, radiographic and histopathologic features. This tumor is locally aggressive, inducing important facial deformation and tooth displacement. Radical treatment with surgery or prosthesis is needed due to the high rate of recurrence.
