A case of sarcoidosis mimicking Wegener’s granulomatosis

Simultaneous Occurrence of Sarcoidosis and Anti-neutrophil Cytoplasmic Antibody in a Patient presented with chronic sinusitis

“…Paraclinical data included hypercalciuria, high levels of ACE, and negative ANCA. This patient had sarcoidosis that mimicked GPA [5]. Petri et al described a 24-year-old woman with a history of sarcoidosis with pulmonary and hepatic involvement followed by foot drop, uveitis, eosinophilia, leg ulcers, and sinus opacification.…”

“…Sarcoidosis may mimic or follow granulomatosis with polyangiitis vasculitis [4][5][6][7][8]. Nazemi et al reported a 41-year-old man presenting with violaceous plaques, dyspnea, recurrent sinusitis, nasal bleeding, and asthma.…”

“…Sarcoidosis and GPA are granulomatous diseases with major expressions in common sites, such as the respiratory tract, kidneys, skin, nervous system, eye and orbit, musculoskeletal system, and heart [3]. The two diseases may mimic or, rarely, follow each other [4][5][6][7][8]. We report an unusual case of a patient presenting with sarcoidosis that remitted with therapy who developed granulomatosis with polyangiitis vasculitis three years later.…”
