内容紹介
Summary
A 60s woman was followed-up regularly for primary biliary cholangitis and a solitary enlarging hepatic mass in the S6 segment of her liver was discovered by ultrasonography. We diagnosed the mass as hepatocellular carcinoma by contrast ultrasonography, contrast computed tomography, and ethoxbenzyl magnetic resonance imaging and laparoscopic partial hepatectomy of S6 segment was performed. The resected specimen was histopathologicaly diagnosed as liver-reactive lymphoid hyperplasia(RLH). The patient is alive without recurrence 17 months after the surgery. Although liver RLH is a rare disease, it should be considered in the differential diagnosis of small liver tumors.
要旨
症例は60歳台,女性。原発性胆汁性胆管炎で外来経過観察中,超音波検査にて肝S6に増大傾向を示す単発の肝腫瘤を認めた。腹部造影超音波検査や腹部造影CT検査,腹部EOB-MRI検査にて肝細胞癌と診断し,腹腔鏡下肝S6部分切除術を施行した。切除標本の病理組織学的検査では肝reactive lymphoid hyperplasia(RLH)と診断された。術後17か月経過した現在,無再発生存中である。肝RLHの頻度はまれであるが,肝臓の小型腫瘍の鑑別診断として念頭に置く必要がある。
