Granulomatosis with polyangiitis: A case report and brief review of literature

Subglottic Stenosis as a Presentation of Antineutrophil Cytoplasmic Antibody-Associated Glomerulonephritis

Granulomatosis with polyangiitis (GPA), previously Wegener's granulomatosis, is a necrotizing vasculitic disease process affecting the small- and medium-sized blood vessels. GPA is frequently associated with damage to the respiratory tract and kidneys but often affects other organ systems including the eyes, nasopharynx, and nervous system. Due to the vague nature of presenting symptoms and the progressive nature of GPA, it is essential to keep a broad differential to mitigate the high morbidity and mortality associated with the disease. Here we introduce a case of a GPA presenting as respiratory distress, stridor, and renal injury. We also review common clinical presentations, diagnostic evaluation, and treatment options.

Childhood-Onset Granulomatosis With Polyangiitis as a Palatal Defect: A Case Report

Granulomatosis with polyangiitis (GPA) is a necrotizing systemic vasculitis of small and medium-sized vessels with renal and sinopulmonary involvement. Its symptoms include chronic sinusitis, recurrent pneumonia, glomerulonephritis, constitutional symptoms, and skin manifestations with a typical onset in the fourth to sixth decade of life. We present a rare case of GPA in a 16-year-old female who presented with facial numbness and nasal regurgitation via a palatal defect. The patient reported a several-month history of recurrent epistaxis and chronic nasal congestion accompanied by several weeks of night sweats, lower right-sided facial numbness and pain, nasal regurgitation of food and liquids, and a 30-pound weight loss. A physical exam found a 3-cm defect on the right side of her palate. CT of the sinuses showed significant sinonasal destruction and petrous apicitis. GPA was confirmed via pathognomonic chest X-ray findings and biopsy results. The patient was treated with maxillary antrostomy and anterior ethmoidectomy and a follow-up was scheduled to address sequelae of the destructive sinopulmonary lesions. This case report highlights a unique presentation of GPA with an insidious development of autoimmune sinonasal destruction in an adolescent female. This presentation is rare and highlights the importance of considering autoimmune disease in cases of tissue destruction where the etiology is not apparent, even in patients at low risk for autoimmune conditions.

Granulomatosis with polyangiitis with salivary glands involvement: Presenting a case and describing its clinical, pathophysiological, and therapeutic aspects

Granulomatosis with polyangiitis (GPA), a rare form of small vessel vasculitis, may be manifested by multisystem involvement misleading its definitive diagnosis. The involvement of salivary glands is a very rare characteristic of GPA. Herein, we described a case of GPA with submandibular salivary gland involvement followed by reviewing the literature on similar cases. The case was a 31-year-old man, a known case of seronegative peripheral arthritis that referred recently with bilateral enlargement of the parotid and submandibular glands. Pulmonary nodules were also evident in the patient's CT scan. Fine-needle aspiration under ultrasound guidance indicated the presence of degenerated squamoid cells, giant cells, and inflammatory cells with a priority of neutrophils in the submandibular gland, as well as the presence of a cyst containing fluid without the evidence of malignancy in the parotid gland. The positivity for the Anti-neutrophil Cytoplasmic Antibody (C-ANCA) marker was also revealed. The patient was treated with methotrexate, prednisolone, and rituximab which led to a gradual reduction in the size of the glands and the improvement of the patient's clinical symptoms within 1 month after the treatment. Enlargement of salivary glands in the context of inflammatory disorders can raise doubts about the existence of GPA, and therefore imaging evaluation and histopathological assessment with an ANCA test will be necessary to confirm or rule out it.

[Granulomatosis with polyangiitis with head and neck symptoms as the first clinical manifestation: clinical analysis of 28 cases]

Objective:To investigate the early clinical features and diagnosis of granulomatous polyangiitis（GPA） with head and neck symptoms as the first presentation. Methods:The data of 28 patients with GPA diagnosed in the Second Hospital of Shanxi Medical University from 2014 to 2021, whose first symptoms appeared on the head and neck, were collected. All patients underwent relevant imaging examinations, laboratory tests, endoscopy, and pathological tissue biopsies. Systemic glucocorticoid or combined immunosuppressive therapy was administered and followed up for 1-5 years. Results:Two patients refused treatment and were lost to follow-up; 26 patients were discharged with improved symptoms, complaining of nasal ventilation, resolution of supraorbital swelling, reduced dyspnoea, and renal symptoms. Five patients were repeatedly admitted to the hospital due to recurrent renal involvement. Conclusion:Although GPA often begins with head and neck symptoms, it is non-specific and can easily be confused with chronic inflammatory disease, leading to misdiagnosis. If suspicious cases are identified, they should be combined with endoscopy, pathological tissue biopsy, and special laboratory tests as early as possible to shorten the time to diagnosis, and obtain early diagnosis and treatment.

Giant cell arteritis: A case report and review of literature

Giant cell arteritis, the most common form of vasculitis in the elderly, is characterized by granulomatous inflammation of arteries, which can lead to serious, life-threatening conditions including aortic aneurysms, ruptures, and dissections as well as blindness. Since GCA can be treated by immunosuppressant therapy, such as corticosteroids, early diagnosis and treatment may reduce the risk of serious disability and morbidity. While temporal artery biopsy is considered the gold standard to diagnosis giant cell arteritis, it is intrusive with inherent risks as well as unreliable due to tissue sampling. Imaging studies, such as computerized tomography, are nonintrusive and have been shown to identify vasculitis including giant cell arteritis. We present a case of a 72-year-old male patient who was diagnosed with giant cell arteritis by temporal artery biopsy during surgery for aortic aneurysm and coronary artery bypass graft. Computerized tomography imaging studies, prior to the surgery and biopsy, were suggestive of vasculitis. This case serves to emphasize the beneficial role of imaging studies to assess vasculitis, including giant cell arteritis, that can be done prior to the progressive development of more serious debilitating and potentially fatal pathology.
