Cocaine abuse may be associated with a destructive nasal and pharyngeal process felt to be due to ischemia secondary to vasoconstriction. This report is the first to document a necrotizing granulomatous vasculitis associated with nasal destruction and an oronasal fistula in a chronic cocaine user. Cocaine is an environmental insult that may play a role in triggering cerebral and non-cerebral vasculitis including a necrotizing granulomatous vasculitis of the respiratory tract.

Background And Purpose: Granulomatosis with polyangiitis (GPA) and eosinophilic granulomatosis with polyangiitis (EGPA) are the most common causes of chronic sinusitis from systemic granulomatous diseases. While both are small- to medium-sized vasculitis with necrotizing granulomas, they have different clinical courses and prognoses. High-density sinus opacification has been reported in allergic fungal sinusitis with eosinophilic infiltrates.

Aims: To describe the imaging features of patients presenting with soft tissue masses and a provisional diagnosis of soft tissue tumours, for whom biopsy confirmed the presence of necrotising granulomata consistent with tuberculoma.
Material And Methods: A review of the histopathology database for patients who had a diagnosis of necrotising granulomata in nonspinal sites. Patients with bone and joint-based pathology were excluded.

is a fungal pathogen that can cause lethal disease in immunocompromised patients. Immunocompetent host immune responses, such as formation of pulmonary granulomas, control the infection and prevent disseminated disease. Little is known about the immunological conditions establishing the latent infection granuloma in the lungs.
