説明

<jats:p>We report a 51‐year‐old female patient with adult‐onset type <jats:styled-content style="fixed-case">II</jats:styled-content> citrullinemia (<jats:styled-content style="fixed-case">CTLN2</jats:styled-content>) who had a history of pancreatoduodenectomy for duodenal somatostatinoma with metastases to regional lymph nodes at age 49 years, paying special attention to indications for liver transplantation. At age 50 years, she developed hepatic encephalopathy with elevation of plasma ammonia and citrulline levels. A diagnosis of <jats:styled-content style="fixed-case">CTLN2</jats:styled-content> was made by <jats:styled-content style="fixed-case">DNA</jats:styled-content> analysis of the <jats:italic><jats:styled-content style="fixed-case">SLC25A13</jats:styled-content></jats:italic> gene and treatment with conservative therapies was begun, including a low‐carbohydrate diet and supplementation with arginine and sodium pyruvate. However, despite these treatments, frequent attacks of encephalopathy occurred with markedly elevated plasma ammonia levels. While we were apprehensive regarding the risk of recurrence of somatostatinoma due to immunosuppressive therapy after liver transplantation, the patient was in a critical condition with <jats:styled-content style="fixed-case">CTLN2</jats:styled-content> and it was decided to perform living‐donor liver transplantation using a graft obtained from her son. Her postoperative clinical course was uneventful and she has had an active life without recurrence of somatostatinoma for 2 years. This is the first case of <jats:styled-content style="fixed-case">CTLN2</jats:styled-content> with somatostatinoma. As the condition of <jats:styled-content style="fixed-case">CTLN2</jats:styled-content> patients with rapidly progressive courses is often intractable by conservative therapies alone, liver transplantation should be considered even after surgery for malignant tumors in cases with neither metastasis nor recurrence.</jats:p>
