Strawberry gingivitis: Challenges in the diagnosis of granulomatosis with polyangiitis on gingival specimens

Strawberry gingivitis as an initial presentation of granulomatosis with polyangiitis in an older adult

OBJECTIVE

To describe a rare case of granulomatosis with polyangiitis (GPA) in an older adult in light of the existing literature.

BACKGROUND

GPA is a potentially life-threatening multisystem necrotising vasculitis, characterised by a spectrum of oral mucosal lesions that present diagnostic challenges.

MATERIALS AND METHODS

A 76-year-old female patient presented with asymptomatic granular and haemorrhage swelling ("strawberry" gingivitis) affecting the upper and lower anterior and posterior gingivae. Cytoplasmic antineutrophil cytoplasmic antibody (ANCA) was positive. Concurrent kidney lesions were diagnosed.

RESULTS

Histopathological examination revealed a pseudoepitheliomatous proliferation with perivascular inflammation and a dense eosinophilic infiltrate. After a 5-year follow-up, the patient showed no signs of recurrence. A literature review performed using PubMed, Web of Science and Scopus identified 22 documented cases of GPA-related oral lesions in older adults, with equal sex distribution and 63.6% occurring in the seventh decade of life.

CONCLUSION

Early recognition and diagnosis of "strawberry" gingivitis in older adults with GPA are crucial, as these oral manifestations may be the initial presentation of the disease.

Increased frequency of oral plasma cell mucositis/plasma cell gingivitis after the COVID-19 pandemic: a 23-year retrospective analysis and review of diagnostic challenges relating to this condition

OBJECTIVE

Oral plasma cell mucositis (PCM) or localized plasma cell gingivitis (PCG) is an idiopathic inflammatory condition often associated with hypersensitivity reactions. This study aimed to evaluate the frequency and features of PCM/PCG in a large biopsy service over a time period of more than 20 years.

STUDY DESIGN

The biopsy archives at University of Florida College of Dentistry were searched from 2000 through the first quarter of 2023 for cases of oral PCM or PCG. Case data were aggregated and analyzed.

RESULTS

A total of 107 cases were included. Between 2000 and 2019, PCM/PCG was diagnosed in 0.03% of all biopsy cases. Starting in 2020 through 2023, the percentage of biopsies diagnosed as PCM/PCG increased threefold to 0.10% of all biopsy cases, and the mean patient age increased by 3 years. There were no statistically significant differences between cases diagnosed from 2000 to 2019 and those from 2020 to 2023 regarding age, sex, location, or histology.

CONCLUSIONS

A significant increase in PCM/PCG was identified in this study at one institution coinciding with the start of the COVID-19 pandemic. Further investigation is recommended to determine if this is a widespread phenomenon and identify possible etiologic mechanisms.

Oral manifestations of anti-neutrophil cytoplasmic antibody-associated vasculitis: an update and narrative review of the literature

Anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) is a multisystem disorder of small blood vessels subdivided into granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), and eosinophilic granulomatosis with polyangiitis (EGPA). Oral manifestations (OMs) have been reported to include mucosal ulceration, gingival enlargement, alveolar bone necrosis, tooth loss, oro-antral communication, palatal perforation, parotitis, and candidal infection mainly in GPA. They may appear during the course of the disease, as a disease flare-up, or as the presenting sign. These OMs are often nonspecific and can mimic an array of conditions, therefore formulating a differential diagnosis can be challenging. This review updates the OMs of GPA, and, for the first, time includes OMs of other AAVs. It provides recommendations for the overall assessment and the diagnosis and management of all AAV OMs with considerations for treatment coordination. The role of oral health care providers in multidisciplinary care is highlighted.

Oral granulomatosis with polyangiitis a systematic review

OBJECTIVE

Granulomatosis with polyangiitis is an unusual multisystemic inflammatory disease, with vasculitis of small- and medium-sized vessels, with a predilection for upper lower airways and kidneys. The etiology remains unknown although it may originate from different stimuli, in genetically susceptible patients.

MATERIALS AND METHODS

A detailed database search was performed. The variables were demographics, localization, histopathological findings, antineutrophil cytoplasmic autoantibody, cytoplasmic (c-ANCA) tests, treatment, and follow-up.

RESULTS

Fifty-two cases were identified; the mean age was 49.6 years, with a range from 6 to 87 years. It was most frequently seen in females (57.7%). The most common race was white (59.6%). The most frequent location was in the maxillary gingiva (28.8%), followed by both the upper and lower gingiva (19.2%). The most common clinical presentation was "strawberry gingivitis" (61.5%). The main symptom was pain, in 50%. Regarding the c-ANCA test, it was positive in 71.2% of cases. The most common therapy was prednisone and cyclophosphamide, utilized in 51.9%. The average follow-up was 23.6 months, and 88.5% of patients were still alive at follow-up.

CONCLUSION

The diagnosis initially was difficult to establish, an early diagnosis and treatment are mandatory. If untreated the disease can be associated with morbidity and mortality. For the oral clinician, this disease needs to be addressed in the differential diagnosis of oral lesions.

Granulomatosis with polyangiitis in gingiva: A rare case of isolated presentation

Granulomatosis with polyangiitis (GPA) is a rare autoimmune disease characterized by necrotising granulomatous inflammation of upper and lower respiratory tract, vasculitis and glomerulonephritis. This ailment may present with cough, haemoptysis, sinusitis, nasal deformity, skin lesions, malaise, fever, anorexia, and weight loss. Oral manifestation includes strawberry gingivitis, which is a pathognomonic clinical presentation. Here, we present a case of GPA in gingiva as the first manifestation. Clinical examination of the oral cavity revealed granular, erythematous gingival enlargement in the lower anterior teeth region involving papilla, marginal and attached gingiva with shiny and pebbled surface. Histopathological examination showed pseudoepitheliomatous hyperplasia with vasculitis and inflammation in the connective tissue, neutrophilic infiltration and abscess formation with haemorrhage were noted. Laboratory investigations revealed Proteinase 3 (PR3) antigen and Glomerular basement membrane (GBM) antigen were positive. Clinical, histopathological and laboratory investigations enabled the diagnosis of Granulomatosis with Polyangiitis. We present this rare case report of GPA with primary manifestation in gingiva.

Granulomatosis with polyangiitis mistaken as a temporomandibular joint disorder: A case report

INTRODUCTION

Granulomatosis with polyangiitis (GPA), is a rare systemic disease that if left untreated, it may lead to death within 6-12 months. This case report describes a 15-year-old female with a 14-month history of epiphora, nasal breathing difficulties, headaches, and jaw pain. The patient reported having various medical procedures attempted to address her symptoms. The classical presentation of strawberry gingivitis led to the diagnosis of GPA. Based on a multi-language search, this is the first reported case, that GPA is mistaken as Temporomandibular Joint Disorders (TMD).

CASE PRESENTATION

A 15-year-old female with nearly 14 months of numerous complaints, including headaches and jaw pain, was referred for an orofacial pain (OFP) consultation. The patient had completed a dental examination and was prescribed chlorhexidine for gingivitis control. The OFP examination was not consistent with signs and symptoms of TMD. However, the gingival appearance of strawberry gingivitis was suggestive of GPA. A rheumatologist confirmed the diagnosis of GPA based on the clinical interview, serology testing, and dental findings. A course of rituximab and corticosteroids, and regular dental cleanings were recommended. A 4-month follow-up visit demonstrated complete resolution of her jaw pain and headaches. Gingival tissue appeared normal.

CONCLUSION

This case emphasizes the need for familiarity with systemic diseases that can present oral manifestations. It also stresses the importance for dental professionals to be knowledgeable of differential diagnoses for TMD, headaches, and autoimmune disorders. Why is this case new information? This is believed to be the first published case mistaking GPA as TMD. This is a case in which a multidisciplinary approach and management were keys for a successful treatment outcome. What are the keys to successful management of this case? Obtain a thorough clinical history. Know the oral manifestation of systemic diseases. Know differential diagnosis of TMD and headaches. What are the primary limitations to success in this case? Having no access to the medical records during the OFP consultation. Having no awareness of differential diagnosis for gingivitis: strawberry, plaque-induced.

Oral Granulomatous Disease

Granulomatous diseases are chronic inflammatory disorders whose pathogenesis is triggered by an array of infectious and noninfectious agents, and may be localized or a manifestation of systemic, disseminated disease. As in the skin, oral manifestations of granulomatous inflammation are often nonspecific in their clinical appearance. Thus, in the absence of overt foreign material or a recognizable infectious agent, identifying the underlying cause of the inflammation can be challenging. This article highlights various conditions known to induce granulomatous inflammation within the oral soft tissues.

From strawberry gingivitis to palatal perforation: The clinicopathological spectrum of oral mucosal lesions in granulomatosis with polyangiitis

BACKGROUND

Reports of oral manifestations of granulomatosis with polyangiitis (GPA) usually refer to single-case reports; "strawberry gingivitis" has been increasingly reported.

OBJECTIVE

To study the clinicopathological findings of four patients in which the diagnosis of GPA was suspected from the observation of their oral lesions and compare these to existent data.

METHODS

Retrospective study of a case series.

RESULTS

One patient presented typical "strawberry gingivitis" with localized disease and negative ANCA results. Two patients presented rapidly growing oral ulcers associated with systemic compromise and high ANCA levels. One patient presented with a chronic granulomatous lesion that leaded to palatal perforation.

CONCLUSION

Oral manifestations of GPA may vary from rapidly evolving lesions in acutely ill patients to chronic and locally destructive lesions in slowing developing disease. These differences are also evident in the histopathological findings.
