Granulomatous cheilitis and Borrelia burgdorferi: polymerase chain reaction and serologic studies in a retrospective case series of 12 patients

Identification of Putative Bacterial Pathogens for Orofacial Granulomatosis Based on 16S rRNA Metagenomic Analysis

Orofacial granulomatosis (OFG) is a chronic inflammatory disease characterized by nontender swelling of the orofacial tissues, the underlying cause of which remains unknown. Our previous study demonstrated that tooth apical periodontitis (AP) is involved in the development of OFG. To characterize the AP bacterial signatures of OFG patients and identify possible pathogenic bacteria that cause OFG, the compositions of the AP microbiotas in OFG patients and controls were compared using 16S rRNA gene sequencing. Pure cultures of putative bacterial pathogens were established by growing bacteria as colonies followed by purification, identification, and enrichment and then were injected into animal models to determine the causative bacteria contributing to OFG. A specific AP microbiota signature in the OFG patients was shown, characterized by the predominance of phyla Firmicutes and Proteobacteria, notably members of the genera Streptococcus, Lactobacillus, and Neisseria, were found. Streptococcus spp., Lactobacillus casei, Neisseria subflava, Veillonella parvula, and Actinomyces spp. from OFG patients were isolated and successfully cultured in vitro and then injected into mice. Ultimately, footpad injection with N. subflava elicited granulomatous inflammation. IMPORTANCE Infectious agents have long been considered to play a role in the initiation of OFG; however, a direct causal relationship between microbes and OFG has not yet been established. In this study, a unique AP microbiota signature was identified in OFG patients. Moreover, we successfully isolated candidate bacteria from AP lesions of OFG patients and assessed their pathogenicity in laboratory mice. Findings from this study may help provide in-depth insights into the role of microbes in OFG development, providing the basis for targeted therapeutic approaches for OFG.

A case of complete Melkersson-Rosenthal syndrome: Possibly associated with Mycolicibacterium fortuitum from odontogenic origin

Melkersson-Rosenthal syndrome (MRS) is a neuromucocutaneous disease of unknown pathogenesis. With this communication, we describe a case of a 26-year-old woman with complete MRS in whom Mycolicibacterium fortuitum was detected in the swelling lip biopsy by next- generation sequencing. The patient's symptoms were slightly improved after intralesional corticosteroid injection combined with broad-spectrum antibiotics, while they were significantly improved after further treatment of dental caries and removal of the residual root. This case provides insight into the possible microbial infection pathogenesis of MRS, and M. fortuitum was speculated to be related to granulomatous and neuronal disorders, most probably from odontogenic origin.

Offense and Defense in Granulomatous Inflammation Disease

Granulomatous inflammation (GI) diseases are a group of chronic inflammation disorders characterized by focal collections of multinucleated giant cells, epithelioid cells and macrophages, with or without necrosis. GI diseases are closely related to microbes, especially virulent intracellular bacterial infections are important factors in the progression of these diseases. They employ a range of strategies to survive the stresses imposed upon them and persist in host cells, becoming the initiator of the fighting. Microbe-host communication is essential to maintain functions of a healthy host, so defense capacity of hosts is another influence factor, which is thought to combine to determine the result of the fighting. With the development of gene research technology, many human genetic loci were identified to be involved in GI diseases susceptibility, providing more insights into and knowledge about GI diseases. The current review aims to provide an update on the most recent progress in the identification and characterization of bacteria in GI diseases in a variety of organ systems and clinical conditions, and examine the invasion and escape mechanisms of pathogens that have been demonstrated in previous studies, we also review the existing data on the predictive factors of the host, mainly on genetic findings. These strategies may improve our understanding of the mechanisms underlying GI diseases, and open new avenues for the study of the associated conditions in the future.

Melkersson-Rosenthal syndrome with coeliac and allergic diseases

A 45-year-old man presented with a 10-year history of relapsing oedema of the lips. Moreover, he exhibited recurrent facial nerve palsy since the age of 10 years, coeliac disease since the age of 12 years, atopic eczema, allergic rhinitis and asthma. Physical examination revealed lip swelling and lingua plicata. Thus, he presented the classic triad of Melkersson-Rosenthal syndrome which includes recurrent orofacial oedema, facial nerve palsy and fissured tongue. A lip biopsy confirmed our clinical diagnosis.This case is particularly rare, as the classic triad is seen only in a minority of the cases. Moreover, allergic and coeliac diseases were observed concomitantly. This paper illustrates a potential pathophysiological interconnection between these pathologies in which interferon gamma could play a key role. To our knowledge, this is the first case report in which Melkersson-Rosenthal syndrome has been observed concurrently with coeliac disease.

Streptococcus Salivarius: A Potential Salivary Biomarker for Orofacial Granulomatosis and Crohn's Disease?

BACKGROUND

Orofacial granulomatosis (OFG) is a rare disease characterised by chronic, noncaseating, granulomatous inflammation primarily affecting the oral cavity. Histologically, it is similar to Crohn's disease (CD), and a proportion of patients have both OFG and CD. The cause of OFG remains elusive, but it has been suggested that microbial interactions may be involved. The aim of this study was to compare the salivary microbial composition of subjects with OFG and/or CD and healthy controls.

METHODS

Two hundred sixty-one subjects were recruited, of whom 78 had OFG only, 40 had both OFG and CD, 97 had CD only with no oral symptoms, and 46 were healthy controls. Bacterial community profiles were obtained by sequencing the V1-V3 region of the 16S rRNA gene.

RESULTS

There were no differences in richness or diversity of the salivary bacterial communities between patient groups and controls. The relative abundance of the Streptococcus salivarius group was raised in patients with OFG or CD only compared with controls, whereas that of the Streptococcus mitis group was lower in CD compared with both OFG and controls. One S. salivarius oligotype made the major contribution to the increased proportions seen in patients with OFG and CD.

CONCLUSIONS

The salivary microbiome of individuals with OFG and CD was similar to that found in health, although the proportions of S. salivarius, a common oral Streptococcus, were raised. One specific strain-level oligotype was found to be primarily responsible for the increased levels seen.

Orofacial granulomatosis: A case report of three cases may be caused by apical periodontitis

RATIONALE

Orofacial granulomatosis (OFG) is a rare disease characterized by noncaseating granulomatous inflammation. The most common clinical presentation is persistent swelling of the soft tissues in the oral and maxillofacial regions. The precise cause of OFG is unknown. Corticosteroids are the first-line and best treatment, but there is lack of uniform treatment prescription and standard. It is important to identify the pathogen in order to improve treatment specificity.

PATIENT CONCERNS

Three patients presented with recurring lip swelling and cobblestone formation on buccal mucosa, complained of toothache or dental caries for many years. They had very similar and characteristic clinical signs, especially the corresponding location with infected teeth, which suffered from apical periodontitis.

DIAGNOSES

The three patients were all diagnosed with typical clinical signs and non-caseating epithelioid cell granulomas histologically.

INTERVENTIONS

The teeth with apical periodontitis were extracted or treated and corticosteroids were prescribed locally or/and systematically.

OUTCOMES

A complete resolution of lip swelling and cobblestone formation were shown after treatment.

LESSONS

This is the first report to highlight that apical periodontitis may intrigue the pathogenesis of OFG, which suggested that dental infection may be the direct and initial etiology of OFG. Removal of infected teeth should be performed as soon as possible in order to reduce the dosage of corticosteroids and occcurence rate of OFG.

A Diagnostic Approach to Recurrent Orofacial Swelling: A Retrospective Study of 104 Patients

OBJECTIVE

To identify patients evaluated in an outpatient setting at our institution with a presentation of recurrent orofacial swelling and to review the spectrum of causes to outline a diagnostic approach.

PATIENTS AND METHODS

A retrospective study of 104 patients with more than 1 episode of orofacial swelling lasting for more than 5 days identified through a keyword search of the electronic health record from January 2, 2000, through July 5, 2011.

RESULTS

Patients were categorized according to final cause of orofacial swelling: idiopathic orofacial granulomatosis, solid facial edema due to rosacea and acne vulgaris, Crohn disease, contact dermatitis, sarcoidosis, exfoliative cheilitis, lichen planus, actinic cheilitis, cheilitis glandularis, lymphedema, miscellaneous, and multifactorial. Granulomatous inflammation was noted on biopsy in 40 of 85 patients (47%). Oral involvement was associated with Crohn disease (P<.001), and facial and periorbital swelling was associated with solid facial edema in the setting of rosacea and acne vulgaris (P<.001).

CONCLUSION

The broad range of diagnoses responsible for recurrent orofacial swelling underscores the diagnostic challenge and importance of a thorough multidisciplinary evaluation to identify underlying causes.

Orofacial Granulomatosis

Orofacial granulomatosis (OFG) is an uncommon chronic inflammatory disorder of the orofacial region. It is characterized by subepithelial noncaseating granulomas and has a spectrum of possible clinical manifestations ranging from subtle oral mucosal swelling to permanent disfiguring fibrous swelling of the lips and face. Etiopathogenesis is unknown. A range of systemic granulomatous disorders, including Crohn disease and sarcoidosis, may cause orofacial manifestations that cannot be distinguished from those of OFG. Treatment of OFG has proven difficult and unsatisfactory, with no single therapeutic model showing consistent efficacy in reducing orofacial swelling and mucosal inflammation.

Orofacial granulomatosis: clinical signs of different pathologies

Orofacial granulomatosis (OFG) is an uncommon disease characterized by persistent or recurrent soft tissue enlargement, oral ulceration and a variety of other orofacial features. It could be an oral manifestation of a systemic disease. For a correct differential diagnosis, local and systemic conditions characterized by granulomatous inflammation should be excluded using appropriate clinical and laboratory investigations. In fact, the diagnosis of OFG may be confirmed only by histopathological identification of noncaseating granulomas. The literature from 1943 to 2014 was reviewed with emphasis on the etiology of OFG and on clinical manifestations of systemic pathologies associated with OFG. The precise cause of OFG is still unknown, although several theories have been suggested, such as infection, hereditary factors and allergy. OFG is a disease that has a wide spectrum of presentation, which may include the oral manifestation of a systemic condition such as Crohn's disease, sarcoidosis, granulomatosis with polyangiitis and Melkersson-Rosenthal syndrome.

Granulomatous cheilitis: successful treatment of two recalcitrant cases with combination drug therapy

Granulomatous cheilitis is a rare, idiopathic, inflammatory disorder which usually affects young adults. It is characterized by persistent, diffuse, nontender, soft-to-firm swelling of one or both lips. Various treatment modalities have been suggested. In spite of the best treatment, recurrence of the disease is very common. We report two cases of granulomatous cheilitis treated with a combination of steroids, metronidazole, and minocycline with no signs of relapse at one-year follow-up.

Melkerrson-Rosenthal Syndrome, a rare case report of chronic eyelid swelling

Abstract

Melkerrson-Rosenthal syndrome is a rare disorder of unknown etiology. The classical triad of recurrent facial paralysis, swelling of the face, lips and deep furrowed tongue (Lingua Plicata) is seen in very few cases, majority of the patients often present with one or two symptoms only, which often leads to misdiagnosis and mismanagement. Clinically these symptoms vary from days to years, which further delay the definitive diagnosis and symptoms may eventually become permanent. The cause of this entity is not very well understood, but thought to be attributable to multiple entities including genetic and Infectitious. As this entity has been associated with numerous other clinical entities, diagnosis often remains an exclusion process. Methods: A middle age male with a chronic history of heavy eyelids with skin indurations predominately around left eye was presented to ophthalmology clinic. Physical examination revealed a deep furrowed tongue. The skin biopsy from left eyelid revealed a non-specific granulomatous lesion. The clinical correlation of facial swelling and deep plicated tongue prompted the differential of MRS Results: Histologically a non-specific granulomatous lesion was seen in dermis. As a rule, other causes of granulomatous diseases were ruled out especially Crohn’s disease and sarcoidosis. Polarization failed to reveal any foreign body. Conclusions: The finding of granulomatous lesion and clinical picture led to the definite diagnosis of Melkerrson-Rosenthal syndrome. Association with rosacea was other findings. Clinically his sign and symptoms are under control and no occurrence of symptoms has been noted so far.

Cheilitis granulomatosa: a review

Cheilitis granulomatosa (CG) is a cosmetically disturbing and persistent idiopathic lip swelling. It is one manifestation of orofacial granulomatosis (OFG), which is a clinical entity describing facial and oral swelling in the setting of non-caseating granulomatous inflammation and in the absence of systemic disease such as Crohn's disease and sarcoidosis. CG can occur by itself or as part of the Melkersson-Rosenthal syndrome, which includes facial palsy and a plicated tongue. Other proposed causes of OFG include dietary allergens such as cinnamon and benzoates. Similar orofacial swelling may be an early manifestation of Crohn's disease or sarcoidosis, and so clinical history is important in diagnosis. The cause of CG has not been wholly elucidated, but a current hypothesis holds that a random influx of inflammatory cells is responsible. Other granulomatous and edematous causes of lip swelling must be investigated prior to diagnosis. Options for treatment include dietary modifications, antibiotics, systemic or intralesional corticosteroids, and surgery, although treatment is not always necessary. CG should be considered in the differential of persistent lip swelling.

Cheilitis granulomatosa: a case report with review of literature

Cheilitis granulomatosa (CG) is a chronic swelling of the lip due to granulomatous inflammation. It is a rare inflammatory disorder first described by Miescher in 1945. It is a monosymptomatic form or an incomplete variant of Melkersson-Rosenthal syndrome; a triad of recurrent orofacial edema, recurrent facial nerve palsy and fissuring of the tongue. As the etiology remains unknown, treatment of CG is challenging. We present a case of CG in a 43-year-old female patient secondary to allergy to certain food items. The present case highlights the importance of thorough investigations in the diagnosis of this lesion as the findings mimic many other granulomatous conditions.

Orofacial granulomatosis: A case report with review of literature

Orofacial granulomatosis (OFG) encompasses conditions characterized by non-necrotizing granulomatous inflammation of the oral and maxillofacial region that present clinically as labial enlargement, perioral and/or mucosal swelling, oral ulcerations, and gingivitis. The unifying term “OFG” has been introduced to integrate the spectrum of various disorders, including Melkersson-Rosenthal syndrome and granulomatous cheilitis (which is sometimes considered to be a monosymptomatic form of Melkersson-Rosenthal syndrome), and has been shown to be associated with Crohn's disease, sarcoidosis, and infectious diseases such as tuberculosis. Although various etiological agents such as food substances, food additives, dental materials, and various microbiological agents have been implicated in the disease process, its precise pathogenesis is yet to be elucidated. Delayed type of hypersensitivity reaction appears to play a significant role, although the exact antigen inducing the immunological reaction varies in individual patients. However, evidence for the role of genetic predisposition to the disease is sparse. The underlying immunological mechanism appears to show some similarities between OFG and Crohn's disease, emphasizing the need for more comparative studies of the two entities. The aim of this article is to report a case of OFG, along with a detailed literature review of the facts and variations associated with its nomenclature, clinical presentation, and etiology. It also projects the challenges that a professional has to face in the diagnosis and treatment planning of such cases.

Orofacial granulomatosis--a 20-year review

Orofacial granulomatosis (OFG) is the presence of persistent enlargement of the soft tissues of the oral and maxillofacial region, characterized by non-caseating granulomatous inflammation in the absence of diagnosable systemic Crohn's disease (CD) or sarcoidosis. Over 20 years have passed since OFG was first described and an extensive review of the literature reveals that there is no consensus whether OFG is a distinct clinical disorder or an initial presentation of CD or sarcoidosis. Furthermore, the precise cause of OFG is still unknown although several theories have been suggested including infection, genetic predisposition and allergy. The clinical outcome of OFG patients continues to be unpredictable. Current therapies remain unsatisfactory. Regular clinical review is indicated to identify the development of gastrointestinal or systemic involvement. The aim of this review was to analyse the developments in our understanding of the aetiology, pathogenesis and treatment protocols, with particular emphasis on management and outcomes of OFG since this entity was first described in 1985.

Orofacial granulomatosis: review on aetiology and pathogenesis

Orofacial granulomatosis (OFG) is considered as an uncommon disease and nomenclature of the disease was subjected to debate for a long time. Although various aetiological agents such as food substances, food additives, dental materials and various microbiological agents have been implicated in the disease process its precise pathogenesis is yet to be elucidated. Delayed type of hypersensitivity reaction appears to play a significant role, although the exact antigen inducing the immunological reaction varies in individual patients. However, evidence for the role of genetic predisposition to the disease is sparse. The underlying immunological mechanism appears to show some similarities between OFG and Crohn's disease, emphasizing the need for more comparative studies of the two entities. Therefore, we propose the term idiopathic OFG as a better term for those cases restricted to oral region without any identifiable known granulomatous disease and the diagnosis should not be changed until the patient develops systemic manifestations of a specific granulomatous condition. This review attempts to discuss the role of different aetiological agents and certain aspects of pathogenesis of OFG.

Granulomatous cheilitis resulting from a tuberculide

Granulomatous cheilitis (GC) is a chronic granulomatous inflammation of the lips of unknown etiology. The possible relationship with tuberculosis has been described although most of the studies excluded infectious agents as potential causes of the granulomatous response. To our knowledge only one case of granulomatous cheilitis resulting from a tuberculide has been reported in the literature but accompanying internal involvement has not been previously described. We report a case of GC resulting from a tuberculide. Investigations showed pulmonary involvement compatible with tuberculosis and improvement following antituberculous chemotherapy for 3 months.

Possible role of Mycobacterium tuberculosis complex in Melkersson-Rosenthal syndrome demonstrated with Gen-Probe amplified Mycobacterium tuberculosis direct test

Melkersson-Rosenthal (MRS) syndrome is characterized by a classical triad of recurrent or persistent orofacial swelling, peripheral facial nerve paralysis and lingua plicata. Granulomatous cheilitis (GC) is regarded as a monosymptomatic form of MRS. The exact aetiologies of MRS and GC are unknown. In this study we investigated the possible role of mycobacteria in these two conditions. A ribosomal RNA amplification-based Gen-Probe amplified Mycobacterium tuberculosis direct test was used to investigate the presence of M. tuberculosis complex in paraffin-embedded skin biopsy specimens from five patients with MRS and one patient with GC. Three of the six specimens were shown to be positive using this system; one of the positive specimens also showed positive Ziehl-Neelsen staining. These results suggest a possible mycobacterial aetiology for MRS and GC.
