Atypical Pathogen

Leukocytoclastic small-vessel vasculitis of the skin (with or without systemic involvement) is often preceded by infections such as common cold, tonsillopharyngitis, or otitis media. Our purpose was to document pediatric (≤18 years) cases preceded by a symptomatic disease caused by an atypical bacterial pathogen. We performed a literature search following the Preferred Reporting of Systematic Reviews and Meta-Analyses guidelines. We retained 19 reports including 22 cases (13 females and 9 males, 1.0 to 17, median 6.3 years of age) associated with a Mycoplasma pneumoniae infection. We did not find any case linked to Chlamydophila pneumoniae, Chlamydophila psittaci, Coxiella burnetii, Francisella tularensis, or Legionella pneumophila. Patients with a systemic vasculitis (N = 14) and with a skin-limited (N = 8) vasculitis did not significantly differ with respect to gender and age. The time to recovery was ≤12 weeks in all patients with this information. In conclusion, a cutaneous small-vessel vasculitis with or without systemic involvement may occur in childhood after an infection caused by the atypical bacterial pathogen Mycoplasma pneumoniae. The clinical picture and the course of cases preceded by recognized triggers and by this atypical pathogen are indistinguishable.

Diffuse alveolar haemorrhage related to an anti-neutrophil cytoplasmic antibody (ANCA)-associated small vessel vasculitis is an extremely rare form of presentation of breast cancer. Here we report the case of a 77-year-old woman with a histological diagnosis of a papillary ductal carcinoma of the breast presenting with a diffuse alveolar haemorrhage secondary to a perinuclear ANCA-associated vasculitis. To our knowledge, this is the first case ever reported of a diffuse alveolar haemorrhage related to an ANCA-associated small vessel vasculitis as a form of presentation of breast cancer. The therapeutic approach of this paraneoplastic vasculitis included the use of corticosteroids and plasmapheresis, a very useful technique to remove endothelial aggressors (circulating antibodies) as a strategy to earn time for a proper therapeutic decision specifically directed for disease modification, but that can also be associated with several severe adverse effects, which are illustrated in our case.

Vasculitis is defined by histologic evidence of inflammation that involves the blood vessels. The diagnosis of a specific primary vasculitic disorder depends on the pattern of organ involvement, the histopathology, the size of affected blood vessels, and the exclusion of diseases that can cause “secondary” vasculitis. This review presents an approach to the patient suspected of having vasculitis, and goes on to discuss small vessel vasculitis, granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis, microscopic polyangiitis, polyarteritis nodosa, Kawasaki disease, large vessel arteritis, and Behçet disease. Figures show classification of the systemic vasculitis syndromes, the relationships among the causes of small vessel (“hypersensitivity”) vasculitis, palpable purpura of the distal extremities, saddle nose deformity, the nodular infiltrates of the lung in granulomatosis with polyangiitis shown on plain radiograph as well as computed tomography, necrotizing scleritis, livedo reticularis, and angiograms of a patient with Takayasu arteritis. Tables list selected laboratory tests for patients with multisystem disease and possible vasculitis, practical comments on immunosuppressive therapies for vasculitis, features of vasculitis, diagnostic criteria for Kawasaki disease, and giant cell arteritis. This review contains 8 highly rendered figures, 5 tables, and 59 references.
