Melkersson-Rosenthal syndrome: a form of pseudoangioedema

Wenn es kein Angioödem ist, was dann? Diagnostisches Vorgehen bei Gesichtsödemen

Gesichtsödeme sind ein relativ häufiges Symptom bei Patienten allergologischer und dermatologischer Kliniken. Die Differentialdiagnose ist breit gefächert und die endgültige Diagnose kann manchmal eine Herausforderung für den Kliniker sein. Das faziale Angioödem selbst umfasst verschiedene Ätiopathologien (histaminerg, bradykinininduziert und weitere), die von anderen Ursachen des Gesichtsödems differenziert werden sollten, etwa allergischer Kontaktdermatitis, granulomatösen Erkrankungen, inflammatorischen Ursachen, Infektionen, Neoplasmen oder paraneoplastischen Syndromen, Autoimmunerkrankungen und anderen Entitäten, die hier als „Sonstige“ bezeichnet werden. Um die richtigen Untersuchungen anzuordnen und eine gezielte Therapie zu verordnen, ist ein angemessener diagnostischer Ansatz ausschlaggebend. Diese Übersicht konzentriert sich auf Entitäten, die mit Gesichtsödem einhergehen, und fasst ihre klinischen Charakteristika zusammen.

If not angioedema, what is it? Diagnostic approach to facial edema

Facial edema is a relatively frequent clinical presentation encountered in patients seen in allergology and dermatology clinics. The differential diagnosis is broad, and sometimes the definitive diagnosis can be a challenge for the clinician. Facial angioedema itself encompasses different etiopathologies (histaminergic, bradykinergic, etc.) that must be distinguished from other causes of facial edema, such as allergic contact dermatitis, granulomatous conditions, inflammatory causes, infections, neoplasms or paraneoplastic syndromes, autoimmune diseases, among other entities hereby referred as miscellanea. A proper diagnostic approach is essential to order the appropriate tests, as well as to prescribe a targeted treatment. This review focuses on entities that present with facial edema and summarize their characteristic clinical features.

Orofacial granulomatosis: Clinical and therapeutic features in an Italian cohort and review of the literature

BACKGROUND

Orofacial granulomatosis (OFG) is characterized by granulomatous inflammation of the soft tissues of maxillofacial region. We explored OFG patients from 10 different Italian centers and summarized the most recent literature data.

METHODS

A review of patients with OFG was carried out. An extensive online literature search was performed to identify studies reporting diagnosis and management of OFG.

RESULTS

Thirty-nine patients were recruited between January 2018 and February 2020. Most of them (97.4%) displayed involvement of the lips, and 28.2% suffered from Melkersson-Rosenthal syndrome. Two patients received diagnosis of CD and one patient of sarcoidosis, suggesting secondary OFG. Oral aphthosis and cervical lymphadenopathy were also described. The mean diagnostic delay was 3.4 years. Histological evaluation was performed in 34/39 patients (87.2%); non-caseating granulomas were found in 73.5% of them. Neurological symptoms (28.2%), gastrointestinal symptoms in absence of overt inflammatory bowel disease (IBD) (20.5%), and atopy (35.9%) were also identified. Therapeutic approaches varied among the centers. Steroids (51.3%) were used with good or partial results. Anti-TNF-α and anti-IgE monoclonal antibodies were used in 6 (15.4%) and 1 (2.6%) patients, respectively, with variable results. Surgery was the choice for 2 patients with good response.

CONCLUSIONS

OFG is a rare and neglected disease showing multiple clinical phenotypes. While early diagnosis is crucial, management is difficult and highly dependent on the expertise of clinicians due to the lack of international guidelines. There is a need to establish registry databases and address challenges of long-term management.

Recurrent granulomatous cheilitis associated with Crohn's disease successfully treated with ustekinumab: case report and literature review

Granulomatous cheilitis, characterized by persistent inflammation of the lips and a granulomatous histology, is sometimes associated with Crohn's disease and is a therapeutic challenge. Reported evidence indicates treatment with an anti-TNF agent (mainly infliximab) is the most recommended therapeutic option after failure of conventional treatments. The clinical case reported the effectiveness of ustekinumab, a monoclonal antibody against interleukins 12/23, to induce the remission of severe and recurrent granulomatous cheilitis in a patient with Crohn's disease.

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.

Angioedema Masqueraders

Angioedema is a common reason for referral to immunology and allergy specialists. Not all cases are in fact angioedema. There are many conditions that may mimic its appearance, resulting in misdiagnosis. This may happen when a clinician is unfamiliar with conditions resembling angioedema or when there is a low index of clinical suspicion. In this article, we explore a list of differential diagnoses based on body parts, including the lips, the limbs, periorbital tissues, the face, epiglottis and uvula, as well as the genitalia, that may pose as a masquerader even to an experienced eye.

Isolated angioedema: An overview of clinical features and etiology

Angioedema can occur in isolation, accompanied by urticaria, or as a feature of anaphylaxis in mast cell-mediated disorders, bradykinin-mediated disorders, as well as in others with unknown mechanisms, such as infections, rare disorders, or idiopathic angioedema. In mast cell-mediated angioedema, other signs and symptoms of mast cell-mediator release are frequently seen. However, clear evidence of mast cell degranulation may be absent in histaminergic angioedema. Bradykinin-induced angioedema is not associated with urticaria or other symptoms of type I hypersensitivity reactions. For many of the known triggers of angioedema, the mechanism is unclear. While mast cell and bradykinin-mediated angioedema are relatively well defined in terms of diagnostic and therapeutic approach, angioedema with unknown mechanisms represents a challenge for patients and clinicians alike. Elucidating the clinical pattern and the possible causes of isolated angioedema is the key to a correct diagnosis. This review summarizes the causes, and clinical features of angioedema, with a focus on isolated angioedema.

Treatment of orofacial granulomatosis: a case report

BACKGROUND

Orofacial granulomatosis is a relatively recent term coined by Wiesenfield et al. in 1985 to define granulomatous lesions of oral mucosa without intestinal involvement. When it presents in a triad encompassing facial nerve palsy, lip swelling, and fissured or furrowed tongue it is called Melkersson-Rosenthal syndrome while monosymptomatic or oligosymptomatic forms are referred to as granulomatous cheilitis. It is an uncommon clinicopathologic entity which is distinct from classic Crohn's disease. The NOD2 variant which is commonly associated with Crohn's has not been shown to have any association with orofacial granulomatosis.

CASE PRESENTATION

We present a case of a 31-year-old white man who had painful swelling of the lip with oral ulcers and difficulty eating for 2 to 3 years. He was diagnosed as having granulomatous cheilitis based on characteristic biopsy findings. There was serologic evidence of Crohn's disease with anti-Saccharomyces cerevisiae antibodies. However, he was not found to have any gastrointestinal involvement based on computed tomography enterography, and upper and lower endoscopies. He failed to respond to nonsteroidal anti-inflammatory drugs, steroids, and dapsone therapy but responded well to high doses of infliximab.

CONCLUSIONS

Our case questions whether granulomatous cheilitis really exists or is it simply a variant of Crohn's disease with only oral presentation. Our patient did not have symptoms of Crohn's disease; moreover, endoscopic studies and computed tomography enterography were unremarkable for evidence of intestinal involvement. Our case is also the first reported case where high-dose infliximab alone has been used with sustained response for approximately 8 months. In conclusion, more research is needed to assess the underlying pathology as well as ideal treatment options for patients with orofacial granulomatosis. We propose that high-dose infliximab should be considered in patients who do not respond to traditional therapies.

Molecularly targeted agents in oculoplastic surgery

PURPOSE OF REVIEW

Significant advances have been made in oncology and rheumatology with the introduction of molecularly targeted agents (MTAs). MTAs consist of monoclonal antibodies and small molecule inhibitors. The purpose of this manuscript is to review the recent applications of MTAs to orbital, lacrimal, and eyelid disease.

RECENT FINDINGS

The use of monoclonal antibodies has been described in the treatment of orbital vascular lesions, lymphoma, and squamous cell carcinoma. Inflammatory conditions treated with monoclonal antibodies include thyroid eye disease, IgG4 disease, and granulomatosis with polyangiitis. Immunotherapy with checkpoint inhibitors has also found applications to orbital disease. Use of small molecule inhibitors has been described in the treatment of basal cell carcinoma, squamous cell carcinoma, and Erdheim-Chester disease. There are many orbital, lacrimal, and eyelid side effects of MTAs with which the oculoplastic surgeon should be familiar, including hypertrichosis, edema, and orbital and eyelid inflammation.

SUMMARY

MTAs represent the future of treatment of oncologic and inflammatory conditions. Application of these agents to orbital, lacrimal, and eyelid disease will continue to expand. Elucidating the molecular mechanisms of oculoplastic disorders will facilitate additional potential pathways that could be targeted for therapy.

Biological agents: what they are, how they affect oral health and how they can modulate oral healthcare

Biological agents - biologics, biologicals or biopharmaceuticals - are any medicinal product manufactured in, or extracted from, a biological source. They are often generated by DNA recombinant biotechnology and several dozen therapeutic monoclonal antibodies (mAbs) are now marketed for a variety of indications, increasingly in the management of inflammatory immune-mediated disorders, transplantation rejection and cancer treatments. Immunomodulatory mAbs are expensive, must be given by injection or infusion and can have adverse effects but are increasingly used and can be highly effective agents. This paper reviews these agents and their increasing relevance to oral science and healthcare.

An extraordinary form of the Melkersson-Rosenthal syndrome successfully treated with the tumour necrosis factor-α blocker adalimumab

Melkersson-Rosenthal syndrome (MRS) is a rare granulomatous inflammatory disease characterised by the triad of orofacial oedema, facial nerve palsy and furrowed tongue. We describe the case of a 29-year-old patient suffering from an oligosymptomatic form of the disease with orofacial oedema, cobblestone pattern on the buccal mucosa and swelling of the tongue, accompanied by intermittent fatigue, influenza-like symptoms, intermittent tinnitus and acute hearing loss. An increase of several autoimmune-associated antibodies was also detected. Treatment with prednisolone, azathioprine or methotrexate failed to adequately control all symptoms in the long term. In the absence of a specific and well-established therapy for MRS, treatment with adalimumab was administered. Under adalimumab, total remission of all symptoms was achieved, indicating that tumour necrosis factor-α blockers are a promising therapeutic option for patients with Melkersson-Rosenthal syndrome.
