Bilateral pyogranulomatous otitis externa with putative cartilage destruction in a dog: A severe case of auricular chondritis?

Auricular chondritis of unknown cause was suspected in a 10-year-old male Bolognese dog with a five-month history of painful bilateral nodular and ulcerative pyogranulomatous dermatitis of the pinnae with putative auricular cartilage destruction. Pain and lesions resolved with immunosuppressive doses of prednisolone, yet the condition resulted in deformity of both pinnae and external canals.

Unveiling the clinical spectrum of relapsing polychondritis: insights into its pathogenesis, novel monogenic causes, and therapeutic strategies.

Relapsing polychondritis is a rare multisystem disease involving cartilaginous and proteoglycan-rich structures. The diagnosis of this disease is mainly suggested by the presence of flares of inflammation of the cartilage, particularly in the ears, nose or respiratory tract, and more rarely, in the presence of other manifestations. The spectrum of clinical presentations may vary from intermittent episodes of painful and often disfiguring auricular and nasal chondritis to an occasional organ or even life-threatening manifestations such as lower airway collapse. There is a lack of awareness about this disease is mainly due to its rarity. In 2020, VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome, a novel autoinflammatory syndrome, was described. VEXAS syndrome is attributed to somatic mutations in methionine-41 of UBA1, the major E1 enzyme that initiates ubiquitylation. This new disease entity connects seemingly unrelated conditions: systemic inflammatory syndromes (relapsing chondritis, Sweet's syndrome, and neutrophilic dermatosis) and hematologic disorders (myelodysplastic syndrome or multiple myeloma). Therefore, this article reviews the current literature on both disease entities.

Beyond the Earlobe: Navigating the Complexities of Relapsing Polychondritis.

A 27-year-old male with no significant past medical history presented with recurrent swelling and pain on the right superior crus of the antihelix initially misdiagnosed as a skin infection. Despite adherence to antibiotic treatment, his condition showed no improvement, leading to further investigation. The patient's detailed clinical examination, family history devoid of autoimmune disorders, and persistent auricular inflammation prompted a reconsideration of the diagnosis. A subsequent biopsy that captured cartilage revealed auricular chondritis, perichondrial inflammation, degeneration of cartilage, and infiltration by inflammatory cells, all of which have been clinically associated with relapsing polychondritis (RP). Relapsing polychondritis (RP) is a rare autoimmune disorder characterized by recurrent inflammation of cartilaginous structures, often leading to progressive anatomical deformation and functional impairment. While RP's pathogenesis involves complex autoimmune mechanisms, its diagnosis is challenging due to its varied clinical presentations. This case highlights the diagnostic challenges of atypical presentations of RP and underscores the importance of considering RP in differential diagnoses of persistent auricular inflammation. It also emphasizes the role of corticosteroids in managing RP and the potential for novel therapeutic pathways, such as Janus kinase inhibitors, in treatment. The case contributes to a deeper understanding of RP's clinical spectrum and management strategies, stressing the need for heightened clinical suspicion in similar atypical cases.

Relapsing Polychondritis in a Patient With Rheumatoid Arthritis: Improved With Pentoxifylline.

Relapsing polychondritis (RP) is a rare autoimmune condition that involves the recurrent inflammation of cartilage throughout the body, with a predilection for auricular and nasal cartilage. Given its rarity and diverse clinical presentations, RP is frequently misdiagnosed or left untreated, which can lead to significant morbidity and mortality. When it is correctly diagnosed, there are no standardized guidelines on the treatment of RP to date. Management of this disease requires a multidisciplinary approach, and about 30% of patients with RP have other autoimmune disorders, further complicating the approach to targeted treatment. Biologic agents (including TNF inhibitors) are commonly used. We present a compelling case of a 46-year-old female with rheumatoid arthritis (well-controlled on adalimumab) and hypothyroidism who presented to the dermatology clinic with recurrent episodes of painful, swollen, and erythematous ears, leading to a clinical diagnosis of relapsing polychondritis. Off-label use of oral pentoxifylline, along with topical corticosteroids, led to significant improvement in her symptoms. Dermatologists play an important role in the diagnosis of this rare disorder, as skin manifestations may be the initial presenting sign of RP. Further research into potentially effective treatments is needed. Timely identification and management of RP may prevent the progression of cartilage destruction, thus improving patients' long-term prognosis and overall quality of life.

Pediatric-Onset Relapsing Polychondritis With Otolaryngeal Manifestations.

Relapsing polychondritis (RP) is a rare autoimmune disease that can present with various clinical manifestations. Among the affected sites, the ear, nose, and throat cartilages are frequently involved, often leading to subtle and episodic symptoms that can be challenging to diagnose. A high index of suspicion is necessary for the early identification of these subtle signs, which can aid in early diagnosis and prompt management. In this report, we present a rare case of pediatric-onset relapsing polychondritis that was initially misdiagnosed as laryngotracheobronchitis.

Relapsing polychondritis in systemic sclerosis: A rare vasculitic mimic.

Introduction: Relapsing polychondritis is a rare, immune-mediated disease characterised by inflammation of cartilaginous structures. Auricular chondritis, sparing the fatty lobule, is the most typical feature, followed by nose and laryngotracheal involvement. Albeit rare, neurologic involvement is reported with relapsing polychondritis. Cranial nerve involvement is the most frequent neurologic manifestation and is probably due to an underlying vasculitic process. Approximately one-third of relapsing polychondritis patients can overlap with other systemic diseases, including other autoimmune connective tissue diseases, but association with systemic sclerosis has very rarely been described. Case description: A 63-year-old woman presented with acute new-onset severe dysphagia, accompanied by hoarseness and preceded by pain, swelling and erythema of the left pinna, unresponsive to antibiotics. She had a history of long-standing limited cutaneous systemic sclerosis. Cranial nerve examination revealed right-sided palatal palsy, and left vocal cord palsy was found on fibreoptic nasendoscopy. Magnetic resonance imaging of the head and neck showed bilateral enhancement of an extracranial segment of the glossopharyngeal and vagus nerves. Clinical features and imaging findings were consistent with relapsing polychondritis, which successfully responded to high-dose steroids. Conclusions: This is a case of relapsing polychondritis mimicking progression of systemic sclerosis, showcasing its challenging features. It emphasises the importance of early diagnosis and prompt management with potential impact on the outcome, while highlighting the complex interplay between these two disease entities and vasculitic mechanisms, which may reflect the shared network of genetic predisposition across autoimmune rheumatic diseases.

Relapsing Polychondritis in a Patient With Auricular Chondritis and Inflammatory Bowel Disease: A Case Report With Literature Review.

Relapsing polychondritis (RP) most commonly presents as inflammation and degeneration of cartilaginous tissue in the auricles, nasal septum, and lungs (in severe instances). RP is a rare autoimmune condition associated with other autoimmune diseases in 30% of cases. The prevalence of gastrointestinal involvement with RP is tenuous; however, there is a growing collection of case studies associating auricular chondritis with concomitant inflammatory bowel disease (IBD), including both ulcerative colitis and Crohn's disease. We report the case of a 35-year-old patient presenting with autoimmune pancreatitis, with a past medical history of Crohn's disease, primary sclerosing cholangitis (PSC), and suspected RP. Although RP is rare, the disease's multiple clinical presentations and recurrent episodic nature can cause significant diagnostic delays and are often overlooked by physicians. Thus, low disease prevalence may be due to under-recognition and under-reporting of disease symptoms. As RP is a clinical diagnosis, increased awareness of the disease presentation and clinical characteristics may increase disease recognition and improve treatment outcomes.

Robust humoral immune response after boosting in children with Multisystem Inflammatory Syndrome in Children.

The exact pathogenesis of Multisystem Inflammatory Syndrome in Children (MIS-C) is unknown. Reports on response to vaccination in children who had MIS-C are lacking. Using prospectively enrolled children, we report on humoral immune responses prior to and after SARS-CoV-2 immune rechallenge. Recurrent auricular chondritis was also noted in one child.

Case Report: Coexistence of Multiple Myeloma and Auricular Chondritis in VEXAS Syndrome.

Vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic (VEXAS) syndrome is an inflammatory disorder caused by somatic UBA1 variants, which are sometimes associated with hematological disorders, including myelodysplastic syndrome (MDS). VEXAS syndrome often overlaps with rheumatic diseases, including relapsing polychondritis. Here, we describe a case of VEXAS syndrome with auricular chondritis and exceptional multiple myeloma (MM). An 83-year-old man was diagnosed with MM, which was treated once by lenalidomide hydrate obtaining a partial response, but the patient did not desire further aggressive therapy. Although the treatment was effective, progressive macrocytic anemia and inflammation of both the ears emerged over the following 2 months. The histological examination of the auricle skin revealed that the perichondrial area was infiltrated by inflammatory cells, leading to the diagnosis of auricular chondritis. He was treated with oral prednisolone 40 mg/day, and his symptoms rapidly resolved. The re-evaluation of the histopathological bone marrow findings revealed vacuoles in the myeloid precursor cells without myelodysplasia-related changes. Sanger sequencing of UBA1 was performed using genomic DNA from peripheral blood leukocytes and revealed a somatic variant (c.122T>C:p.Met41Thr) consistent with VEXAS syndrome. This demonstrates that patients with chondritis can have complications with MM despite the absence of underlying MDS. A strong association exists between UBA1 variants and the risk of MDS; however, it remains elusive whether somatic UBA1 variants contribute to the development of plasma cell dyscrasia without MDS. Hence, we discuss the possible relationship between auricular chondritis and MM on a background of VEXAS syndrome.

Ocular Involvement in Relapsing Polychondritis.

Relapsing polychondritis (RPC) is a rare systemic immune-mediated disease characterized by recurrent inflammation of cartilaginous and proteoglycan-rich tissues throughout the body. Auricular, nasal, tracheal, and articular chondritis and arthritis are common systemic symptoms in patients with RPC. Ocular tissues are also targets of inflammation in RPC, and a variety of ocular symptoms are observed in approximately half of the patients with RPC. Scleritis/episcleritis, uveitis, and conjunctivitis are common symptoms associated with RPC. Less frequently, keratitis, retinopathy, optic neuropathy, muscle palsy, and orbital inflammation are also observed. Ocular inflammation could also be the first manifestation of RPC. Although RPC is a potentially fatal and sight-threatening disease, the rarity of the disease and its protean clinical presentation may lead to delayed diagnosis or misdiagnosis. Given the high prevalence of ocular involvement in RPC, to avoid misdiagnosis, physicians should be suspicious of RPC when they see patients with recurrent ocular inflammatory conditions and various systemic symptoms. In this article, we provide a comprehensive review of ocular manifestations associated with RPC.

Relapsing polychondritis: state-of-the-art review with three case presentations.

BACKGROUND: Relapsing polychondritis (RPC) is a complex immune-mediated systemic disease affecting cartilaginous tissue and proteoglycan-rich organs. The most common and earliest clinical features are intermittent inflammation involving the auricular and nasal regions, although all cartilage types can be potentially affected. The life-threatening effects of rpc involve the tracheobronchial tree and cardiac connective components. Rpc is difficult to identify among other autoimmune comorbidities; diagnosis is usually delayed and based on nonspecific clinical symptoms with limited laboratory aid and investigations. Medications can vary, from steroids, immunosuppressants, and biologics, including anti-tnf alpha antagonist drugs. METHOD: Information on updated etiology, clinical symptoms, diagnosis, and treatment of rpc has been obtained via extensive research of electronic literature published between 1976 and 2019 using PubMed and medline databases. English was the language of use. Search inputs included 'relapsing polychondritis,' 'polychondritis,' 'relapsing polychondritis symptoms,' and 'treatment of relapsing polychondritis.' Published articles in English that outlined and reported rpc's clinical manifestations and treatment ultimately met the inclusion criteria. Articles that failed to report the above and reported on other cartilaginous diseases met the exclusion criteria. RESULT: Utilizing an extensive overview of work undertaken in critical areas of RPC research, this review intends to further explore and educate the approach to this disease in all dimensions from pathophysiology, diagnosis, and management. CONCLUSION: RPC is a rare multi-systemic autoimmune disease and possibly fatal. The management remains empiric and is identified based on the severity of the disease per case. The optimal way to advance is to continue sharing data on RPC from reference centers; furthermore, clinical trials in randomized control groups must provide evidence-based treatment and management. Acquiring such information will refine the current knowledge of RPC, which will improve not only treatment but also diagnostic methods, including imaging and biological markers.

Relapsing Polychondritis: An Updated Review.

Relapsing polychondritis is an immune-mediated systemic disease characterized by recurrent episodes of inflammation of cartilaginous and proteoglycan-rich tissues, resulting in progressive anatomical deformation and functional impairment of the involved structures. Auricular and nasal chondritis and/or polyarthritis represent the most common clinical features, but potentially all types of cartilage may be involved. Because of the pleomorphic nature of the disease, with non-specific symptoms at the onset, the diagnosis of relapsing polychondritis is often delayed. In this review article we provide a comprehensive look into clinical presentation, laboratory and instrumental investigations, diagnostic criteria, and therapeutic options.

Hypertrophic Pachymeningitis as an Early Manifestation of Relapsing Polychondritis: Case Report and Review of the Literature.

Neurological involvement in relapsing polychondritis (RP) is relatively rare. We describe the case of an 80-year-old man who presented with hypertrophic pachymeningitis (HP) together with arthritis as the first manifestation of RP. Auricular chondritis, which subsequently determined the diagnosis of RP, occurred a few weeks after the detection of HP. The neurological symptoms, as well as arthritis, were promptly improved by treatment with corticosteroids. It is generally difficult to diagnose RP in the absence of typical cartilaginous involvement; however, the present case suggests that HP may occur as an early clinical manifestation of RP.

Policondritis recidivante / Relapsing polychondritis

La policondritis recidivante, es una infrecuente enfermedad inflamatoria del tejido conjuntivo, de etiología desconocida. Se caracteriza por inflamación episódica y progresiva de tejido cartilaginoso, principalmente del pabellón auricular, nariz y árbol traqueo-bronquial. Se presenta el caso de una paciente femenina de 58 años, que consulta por enrojecimiento y dolor en pabellón auricular derecho, con episodios previos similares en ambos oídos y nariz, además de estudio por poliartritis simétrica. Al examen físico destaca: eritema, edema y dolor local en pabellón auricular, respetando lóbulo. Con exámenes complementarios normales y presencia de tres criterios característicos de McAdam, se diagnostica policondritis recividante, iniciando prednisona oral, con respuesta favorable. Pese a ser una enfermedad poco frecuente, es importante considerarla en casos recurrentes de eritema y dolor local en regiones cartilaginosas, principalmente en pabellón auricular y nariz, de tal forma de lograr un diagnóstico precoz, para suprimir las crisis y mejorar el pronóstico de estos pacientes.

Relapsing Polychondritis (RP) is a rare inflammatory connective tissue disease of unknown etiology. It is characterized by episodic and progressive inflammation of cartilage tissue, especially ear, nose and tracheobronchial tree. We report the case of 58 year old Chilean female patient, who consulted for redness and pain in the right ear, with similar previous episodes in both ears and nose; along with symmetric polyarthritis study it is presented. Physical examination highlighted erythema, edema and local pain in ear, respecting lobe. With normal complementary examinations and presence of three diagnostic criteria of McAdam y col. relapsing polychondritis diagnosed, initiating oral prednisone, with favorable response. Despite being a rare disease, it is important to consider in recurrent cases of erythema and local pain in cartilaginous regions, mainly in ear and nose, so to achieve early diagnosis, to suppress the crisis and improve the prognosis of these patients.

Clinical and prognostic characteristics of 158 cases of relapsing polychondritis in China and review of the literature.

This work is aimed to study the clinical and prognostic features of relapsing polychondritis (RP) in China. A total of 158 RP cases from 1985 to 2013 in China were included and compared with international case series in terms of clinical features, systemic involvement, differential diagnosis and prognosis. (1) The average age at the onset was 45.3 years old, the average age for initial symptoms was 14.4 months, female/male ratio was 0.7:1 and misdiagnosis rate was 47 %. (2) The incidence of arthritis was lower than that in Caucasians. The incidences of auricular chondritis (68 %: 84-95 %), ocular inflammation (44 %: 49-65 %) and renal involvement (3 %: 7-26 %) were lower, and laryngotracheal symptoms (69 %: 31-67 %), skin (46 %: 4-38 %) and neurological involvement (12 %: 2-8 %) were higher during the follow-up period. The proportion of associated autoimmune disease and systemic vasculitis were 5 and 3 %, respectively, similar to that in Japanese (4 and 2 %), but less than that in Caucasians (12-31 and 8-18 %) except the Francès's study (7 and 3 %). The primary death cause is respiratory failure due to RP, followed by lung infections and cardiovascular events. (3) Juvenile RP (onset ≤18 years) was more severe than adults, similar to results from the Caucasians. However, Chinese juvenile RP had more severe ocular inflammation (57 %: 40-47 %), arthritis (100 %: 71-90 %), cardiovascular (14 %: 3-10 %) and skin involvement (20 %: 10-11 %) than Caucasian juvenile RP. Although sharing most of the clinical features with case series in previous literature, Chinese patients with RP have its unique characteristics.

Policondrite recidivante / Relapsing polychondritis

JUSTIFICATIVA E OBJETIVOS: A policondrite recidivante (PR) é uma doença multissistêmica, caracterizada por inflamação e destruição das cartilagens auriculares, nasais, laringotraqueais e articulares. Ocasionalmente, há o acometimento de outros tecidos. Com poucos relatos na literatura mundial, a PR é uma doença rara, com maior frequência na quarta década de vida. Sua etiologia permanece desconhecida, no entanto, fortes evidências sugerem patogênese autoimune. A PR pode ter curso grave ao comprometer o trato respiratório e levar à sua obstrução, ocasionando o óbito. O objetivo deste estudo foi rever os diversos aspectos clínicos da PR, como sua patogênese, quadro clínico, diagnóstico e tratamento, visando a ampliação do diagnóstico diferencial na clínica médica. CONTEÚDO: Através dos bancos de dados LILACS, Medline/Pubmed e Scielo foram selecionados 61 artigos, sendo estes de pesquisa, revisão de literatura e relato de caso. Utilizaram-se os descritores: policondrite recidivante, policondrite recorrente. O período considerado englobou 87 anos (1923-2010). CONCLUSÃO: A PR é uma doença pouco prevalente com dados restritos na literatura mundial, mas de potencial gravidade. Seus achados clínicos são sugestivos e incluem condrite auricular, nasal e poliartrite. O tratamento estipulado é empírico, e utiliza-se de anti-inflamatórios não esteroides (AINES), glicocorticóides, imunossupressores e em casos refratários, os agentes anti-TNF-α. Devido à possibilidade de evolução grave, a PR deve ter sua suspeita clínica sempre considerada em qualquer faixa etária acometida, visando um diagnóstico precoce e tratamento adequado de acordo com a atividade da doença.

BACKGROUND AND OBJECTIVES: Relapsing polychondritis (RP) is a multisystemic disease characterized by inflammation and destruction of auricular, nasal, laryngotracheal and junction cartilages. Ocasionally, other tissues are affected. With few reports in the world literature, RP is a rare disease, being more prevalent in the fourth decade of life. Its etiology remains unknown. However, strong evidences suggest an autoimmune pathogenesis. The RP may show a severe evolution when the respiratory tract is affected, and could lead to obstruction, causing patient's death. The objective of this study was to perform a literature review about the general clinical aspects of RP, such as its pathogenesis,clinical presentation, diagnosis and treatment, aiming at expanding the differential diagnosis in clinical medicine.CONTENTS: Through the LILACS, Medline/Pubmed and Scielo databases, 61 articles were selected. Among them, there where research articles, literature review and case reports. We used the following keywords: relapsing polychondritis, recurrent polychondritis. The considered period encompassed 87 years (1923-2010). CONCLUSION: RP is a barely prevalent disease, with restricted data in the world literature, but potentially severe. The clinical findings are suggestive of RP, including auricular and nasal chondritis, and polyarthritis. The prescribed treatment is empirical,with drugs such as non-steroid anti-inflammatories (NSAIDs), glucocorticoids, immunosuppressants and, in refractory cases,the anti-TNF-α agents. Due to the possibility of severe outcome of the RP, its clinical suspicion must be always considered in any age group, thus aiming at an early diagnosis and appropriate treatment according to the disease activity.

Changes in peripheral anterior chamber depth of a case of relapsing polychondritis with recurrent secondary angle closure glaucoma section sign.

A case of relapsing polychondritis showed IOP elevations three times during the follow-up due to the angle-closure mechanism. The peripheral anterior chamber depth (ACD) showed a good correlation with IOP elevation, but central ACD did not. The peripheral ACD could be more related to IOP elevation than central ACD.

A Case of Relapsing Polychondritis / 대한이비인후과학회지

Relapsing polychondritis is a rare disorder that involves a multisystem characterized by recurrent inflammation, degeneration of cartilage and connective tissue. The following tissues, in the order of decreasing frequency, may be involved: auricules, joint, nose, eyes, respiratory tract, heart valve and skin. The cause is unknown but an autoimmune mechanism has been thought to be the causative factor. Authors have recently experienced a case of relapsing polychondritis in a 71 year old man diagnosed by direct immunofluoroscene and auricular chondritis.
