림프구 증식증과 유사한 형태로 말단 회장부와 대장을 침범한 만성 림프구성 백혈병 1예 = A Case of Chronic Lymphocytic Leukemia Involvement of the Terminal Ileum and Colon That Was Seen on Colonscopy as a Form of Lymphoid Hyperplasia

다국어 초록 (Multilingual Abstract)

Follicular lymphoid hyperplasia is commonly seen when performing pediatric endoscopy. But in adults, these findings can imply an underlying gastrointestinal or systemic illness, besides the normal variant. On the other hand, colonic involvement of chronic lymphocytic leukemia (CLL) is seen in about 5% to 20% of autopsy cases. However, there have been few reports on the colonoscopic appearance that corresponds to colonic involvement by CLL, and the reported colonoscopic appearances have included polyps, ulcers, granularity, submucosal nodules, erythema, the red ring sign etc. We report here on a case of CLL neoplastic lymphocyte involvement of the terminal ileum and colon as a form of lymphoid hyperplasia, and this was seen when performing colonoscopy.

국문 초록 (Abstract)

만성 림프구성 백혈병의 대장 침범은 사체부검에 의한 연구에 의하면 약 5∼20% 정도이다. 그러나 실제 침범된 대장의 내시경 소견이 보고된 경우는 드물며 용종, 궤양, 과립상, 점막하 결절, 발적, red ring sign 등의 소견들이 보고된 바 있다. 한편 림프구 증식증은 림프계 이외의 조직에 주로 림프구가 침윤하는 것으로 소아에서는 비교적 흔히 발견되고 건강한 성인에서도 발견될 수 있으며 내시경적으로 작은 무경성 용종이나 적색 반점 등으로 관찰된다. 최근 저자들은 내시경 소견상 림프구 증식증과 유사한 형태로 만성 임파구성 백혈병이 말단 회장부 및 대장을 침범한 증례를 경험하여 보고한다.
