초록

목적: 기존 안와 황색육아종이 진단되었던 환자에서 재발된 피부 황색육아종을 통하여 면역글로불린G4관련안질환이 동반 진단된 증례를 보고하고자 한다.
증례요약: 양안의 눈꺼풀 부종을 주소로 38세 남성이 내원하였다. 전안부 및 후극부에서 특이 소견이 관찰되지 않았다. 조직검사상포말조직구 및 토우튼 거대세포가 관찰되며 S100 및 CD1 염색에 음성 소견을 보여 성인황색육아종 진단하 경구 아자씨오프린과 프레드리솔론 치료를 받았다. 4년 뒤 양안의 노란색 눈꺼풀 종괴를 주소로 재내원하였다. 자기공명영상에서 양안 안와 상외측의 대칭적인연부조직 부종이 관찰되었고, 혈액검사상 immunoglobulin G (IgG) 및 IgG4 수치가 상승되었다. 조직검사 후 면역화학염색에서IgG4+/IgG+ 10-20%, IgG4+ 22/고배율시야가 확인되었으며 과거 조직을 재염색하여 IgG4+/IgG+ 40-50%, IgG4+ 59/고배율시야를확인하여 전형적인 면역글로불린G4관련안질환으로 새롭게 진단하였다.
결론: 비특이적인 눈꺼풀 부종환자에서 면역글로불린G4관련안질환을 고려해야 하며, 기존 황색육아종 환자에서도 면역글로불린G4관련안질환이 동반될 수 있다.

영어초록

Purpose: To report a case of immunoglobulin G4 (IgG4)-related ophthalmic disease associated with adult xanthogranulomatous disease.
Case summary: A 38-year-old male with a history of cholecystectomy visited our clinic for bilateral periorbital swelling.
Histopathology of the orbital biopsy showed diffuse infiltration of foamy histiocytes with Touton giant cells and lymphoid follicles, with a diagnosis of adult-onset xanthogranuloma. After excisional biopsy, he was treated with azathioprine and prednisolone.
Four years after treatment, he again visited the clinic due to bilateral, yellowish eyelid masses. Serological examinations were all nonspecific findings, except for elevation of IgG and IgG4 levels. Magnetic resonance imaging showed bilateral symmetric soft tissue enlargement with slightly heterogeneous T1/T2 isosignal intensity, with contrast enhancement at the superolateral aspect of extraconal spaces. Excisional biopsy and blepharoplasty were performed. Immunohistochemical sections showed that the IgG4+/IgG plasma cell ratio was 10-20% and the IgG4 plasma cell count was 22/high power field (HPF). His past sections of 2013 from the pathology department were again stained and showed that the IgG4+/IgG plasma cell ratio was 40-50% and the IgG4 plasma cell count was 59/HPF. Thus, he was definitely diagnosed with IgG4-related ophthalmic disease.
Conclusions: If there is recurrent eyelid swelling, IgG4-related ophthalmic disease should be considered as a differential diagnosis. And the patient with adult xanthogranulomatous disease can be diagnosed with IgG4-related ophthalmic disease.
