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

Overlap syndromes in sarcoidosis: Unveiling the masquerader

As a multi system granulomatous disease, clinical presentations of sarcoidosis are highly variable. In the absence of a stereotypical clinical presentation such as asymptomatic bilateral hilar adenopathy, Lofgren's syndrome, or lupus pernio, a diagnosis of sarcoidosis typically requires 1) compatible clinical presentation, 2) histologic evidence of granulomatous inflammation, and 3) the exclusion of other causes. The clinical presentation of sarcoidosis is often nonspecific and a variety of other causes of granulomatous inflammation can make diagnosing sarcoidosis a challenge for clinicians. "Overlap syndromes" are often used to describe clinical presentations of sarcoidosis that share histologic and clinical features of other diseases, or when the diagnosis of sarcoidosis is made in association with the coexistence of another diagnosis with similar clinical or histologic findings. Because of the risk of diagnostic delay and diagnostic errors, it is vital for clinicians to be familiar with overlap syndromes in sarcoidosis. The coexistence of sarcoidosis with other diseases can also significantly impact disease management and outcomes. This article will review the most current published data on overlap syndromes in sarcoidosis to aid clinicians in diagnosing and managing these complex patients.

Granulomatous cheilitis: differential diagnosis in patients with macrocheilia

Macrocheilia, or lip enlargement, has a varied aetiology, but granulomatous conditions, both infective and non-infective, comprise a significant proportion of patients. Diagnosis starts with clinical investigations while histological examination is required for a definitive diagnosis. In the case presented, a young man presented with painless swelling of upper lip over the past 3 months. Given the clinical history and biopsy results, the diagnosis of granulomatous cheilitis was made which is considered a rare manifestation of metastatic Crohn's disease. Treatment options remain debated, though in the situation presented a conservative approach was adopted, consisting of antibiotics and corticosteroid therapy, which resulted in significant remission in lip swelling without recurrence after a 3-month follow-up.

Granulomatous Sarcoidosis Mimics

Many granulomatous diseases can mimic sarcoidosis histologically and in terms of their clinical features. These mimics include infectious granulomatous diseases, granulomatous reactions to occupational and environmental exposures, granulomatous drug reactions, vasculitides and idiopathic granulomatous conditions. It is important to distinguish sarcoidosis from these mimics, as a misdiagnosis of these diseases may have serious consequences. This manuscript reviews numerous sarcoidosis mimics and describes features of these diseases that may allow them to be differentiated from sarcoidosis. Distinguishing features between sarcoidosis and its mimics requires a careful review of the medical history, symptoms, demographics, radiographic findings, histologic features, and additional laboratory data. Understanding the clinical characteristics of sarcoidosis and its mimics should lead to more accurate diagnoses and treatment of granulomatous disorders that should improve the care of these patients. As the diagnostic criteria of sarcoidosis are not standardized, it is possible that some of these sarcoidosis mimics may represent varied clinical presentations of sarcoidosis itself.

Pathological and Immunohistochemical Characteristics of Granuloma and Lymphatics in Cheilitis Granulomatosa

ABSTRACT

Cheilitis granulomatosa (CG) is an idiopathic, rare, and chronic granulomatous disorder involving the lips. We characterized the pathological and immunohistopathological findings of these granulomas and their relationship with the lymphatic vessels. Pathologically confirmed cases of primary CG from 2001 to 2016 were collected. Cases of inflammatory cheilitis without the presence of granuloma were included in the control group. Demographic data, clinical presentation, response to therapy, and pathological differences were compared. Periodic acid-Schiff and acid-fast stains excluded patients having infections. CD68, CD163, and D2-40 stains demonstrated features of granuloma, macrophage polarization, and the relationship between granuloma and lymphatic vessels. Thirteen patients diagnosed with CG were enrolled. Thirteen people were enrolled in the control group. The granulomas were either mononuclear or sarcoidal. They were predominantly positive for CD68 but negative for CD163. Perilymphatic granulomas were found in all patients. Intralymphatic histiocytosis and lymphatic dilatation were more commonly observed in patients diagnosed with CG than those in controls (54% vs. 15%, P = 0.03 and 92% vs. 23%, P < 0.01). TH1 immune response due to CD68+ M1 macrophages results in CG. Perilymphatic aggregation of macrophages and intralymphatic histiocytosis were important pathological clues for diagnosis.

Oral and Maxillo-Facial Manifestations of Systemic Diseases: An Overview

Many systemic (infective, genetic, autoimmune, neoplastic) diseases may involve the oral cavity and, more generally, the soft and hard tissues of the head and neck as primary or secondary localization. Primary onset in the oral cavity of both pediatric and adult diseases usually represents a true challenge for clinicians; their precocious detection is often difficult and requires a wide knowledge but surely results in the early diagnosis and therapy onset with an overall better prognosis and clinical outcomes. In the current paper, as for the topic of the current Special Issue, the authors present an overview on the most frequent clinical manifestations at the oral and maxillo-facial district of systemic disease.

Clinical Profile of Melkersson-Rosenthal Syndrome/Orofacial Granulomatosis: A Review of 51 Patients

BACKGROUND

Melkersson-Rosenthal syndrome (MRS) is a rare disease characterized by the triad of granulomatous cheilitis, fissured tongue, and facial paralysis. Publications concerning large series are rare in the literature.

OBJECTIVES

To describe the clinical and histopathological characteristics of patients with complete and oligosymptomatic forms of MRS.

METHODS

A retrospective records review was performed for the diagnoses of Melkersson-Rosenthal syndrome, granulomatous cheilitis, and orofacial granulomatosis at oral Diseases Clinic of the Department of Dermatology, University of São Paulo, Brazil (2003, 2017).

RESULTS

A total of 51 patients were included, mean age at presentation 35.69 years. Four patients were younger than 18 years. The complete triad of was observed in 10 patients. The rare findings of granulomatous blepharitis, gingivitis and palatitis are presented. Comorbidities included Crohn's disease (5 patients), migraine headaches (1 patient) and convulsions (2 patients). Granulomatous inflammatory infiltrate was detected in 31 biopsies. Medical therapies included included oral and intralesional steroids, thalidomide, dapsone, azathioprine, tetracycline, methotrexate, and surgery, with variable responses.

CONCLUSIONS

Our report meant to draw attention to the clinical spectrum of this rare disorder, mainly to oligosymptomatic forms and rarer presentations.

Histopathologic features of noninfectious granulomatous disorders involving the skin

Granulomatous dermatoses may represent primary skin inflammation or can serve as the harbinger of a multitude of underlying systemic disorders or drug reactions. Taken together with clinical findings, the microscopic features from skin biopsy can allow recognition of various patterns and facilitate a precise diagnosis. Accurate classification of entities in this category of inflammatory dermatoses may prompt clinicians to investigate for underlying systemic problems, thereby allowing the pathologist to add considerable value in the care of affected patients. This review article categorizes clinical and microscopic features of common and uncommon causes of noninfectious dermal and subcutaneous granulomatous inflammation.

British Society of Gastroenterology consensus guidelines on the management of inflammatory bowel disease in adults

Ulcerative colitis and Crohn's disease are the principal forms of inflammatory bowel disease. Both represent chronic inflammation of the gastrointestinal tract, which displays heterogeneity in inflammatory and symptomatic burden between patients and within individuals over time. Optimal management relies on understanding and tailoring evidence-based interventions by clinicians in partnership with patients. This guideline for management of inflammatory bowel disease in adults over 16 years of age was developed by Stakeholders representing UK physicians (British Society of Gastroenterology), surgeons (Association of Coloproctology of Great Britain and Ireland), specialist nurses (Royal College of Nursing), paediatricians (British Society of Paediatric Gastroenterology, Hepatology and Nutrition), dietitians (British Dietetic Association), radiologists (British Society of Gastrointestinal and Abdominal Radiology), general practitioners (Primary Care Society for Gastroenterology) and patients (Crohn's and Colitis UK). A systematic review of 88 247 publications and a Delphi consensus process involving 81 multidisciplinary clinicians and patients was undertaken to develop 168 evidence- and expert opinion-based recommendations for pharmacological, non-pharmacological and surgical interventions, as well as optimal service delivery in the management of both ulcerative colitis and Crohn's disease. Comprehensive up-to-date guidance is provided regarding indications for, initiation and monitoring of immunosuppressive therapies, nutrition interventions, pre-, peri- and postoperative management, as well as structure and function of the multidisciplinary team and integration between primary and secondary care. Twenty research priorities to inform future clinical management are presented, alongside objective measurement of priority importance, determined by 2379 electronic survey responses from individuals living with ulcerative colitis and Crohn's disease, including patients, their families and friends.

Non-infectious Granulomatous Lesions of the Orofacial Region

Granulomatous lesions of the orofacial region are a heterogeneous group of disorders characterized by a granulomatous reaction to a variety of stimuli. Infectious agents, foreign material, systemic inflammation and metabolic disorders can all be associated with granulomatous inflammation. In the orofacial region primary causes of granulomatosis include foreign body reaction, delayed hypersensitivity to topical agents and idiopathic orofacial granulomatosis. Secondary causes of granulomas include infectious agents, sarcoid, and Crohn disease. For this review, infectious causes of orofacial granulomatosis (OFG) including bacteria, parasites and fungi will not be discussed.

Synchronous Orofacial Granulomatosis in a Patient with Brain Cavernous Hemangioma

Orofacial granulomatosis is a rare granulomatous inflammatory disease, characterized by recurrent orofacial swelling. Infectious, genetic, and immunologic etiologies are suggested, but not fully understood. Herein, we report a case of synchronous orofacial granulomatosis with brain cavernous hemangioma in a 44-year-old female patient, which may be considered paraneoplastic syndrome.

Idiopathic macrocheilia

A 13-year-boy presented with painless swelling of upper and lower lips accompanied with gingival enlargement. The aetiology for these symptoms included vast pathological varieties but none of them could fit in. Clinical features were similar to orofacial graulomatosis but histopathological examination revealed chronic non-specific infection. Therefore, the final diagnosis was made as idiopathic macrocheilia through exclusion criteria. Management with intralesional triamcinolone acetonide 40 mg, twice a week for 3 weeks, resulted in significant remission in lip swelling without recurrence after a 6-month follow-up.
