title: Eosinophilic granulomatosis with polyangiitis complicated by cholecystitis: a case report and review of the literature.
abstract: The objectives are to report an atypical case of eosinophilic granulomatosis with polyangiitis (EGPA) associated with cholecystitis and to review the main clinical features, therapy, and prognosis of it. We present a 49-year-old male with non-classic clinical manifestations of EGPA and EGPA-related cholecystitis. EGPA was diagnosed by histology of the gallbladder after cholecystectomy. In addition, 11 cases of EGPA-associated cholecystitis have been reported and were described in details in this article. Gallbladder involvement is very uncommon in EGPA. All cases reviewed showed multiple organs involved as well as obviously elevated eosinophilic granulocyte proportion with inflammatory index, although antineutrophil cytoplasmic antibody may be negative. All patients in this cohort that showed gallbladder involvement were eventually confirmed with EGPA by histology examination after cholecystectomy. The pathological change could be infiltration of inflammatory mononuclear cells of small- and medium-sized vessels. Of the cases, 91.7% responded well to steroid and immunosuppressant therapy. Gallbladder involvement is a very rare comorbid condition in EGPA. However, it is an important symptom or secondary condition to alert physicians the diagnosis of EGPA. Moreover, timely diagnosis and correct administration in the early stage of this disease could obviously improve the prognosis.
