Objective : Spectrum of hepatic presentation in Langerhans cell histiocytosis (LCH) varies from asymptomatic hepatomegaly to secondary sclerosing cholangitis leading to cirrhosis with or without decompensation. Conventional chemotherapy may be counterproductive in a patient with LCH and hepatic decompensation. We analysed the outcomes of our patients with hepatic presentation of LCH, including their post liver transplant (LT) follow up. Methods: A retrospective analysis was performed on patients with hepatic presentation of LCH referred to our unit. Their clinical profile, chemotherapy protocol, details of LT and survival were analysed. A management algorithm based on the outcomes was proposed. Results: Five of 8 patients were male. Median age of diagnosis was 25(9-48) months. 8(100%) patients had portal hypertension with 4(50%) having decompensated cirrhosis. 6 (75%) patients underwent LT of which 2 had acute decompensation and 4 had sclerosing cholangitis with portal hypertension. Of the two remaining patients, 1 did not tolerate chemotherapy and succumbed, whereas 1 patient after first cycle of chemotherapy was lost to follow up. As their liver disease was worsening during chemotherapy (after 8 & 20 weeks of chemotherapy), two patients underwent urgent LT followed by continuation of chemotherapy. After median follow-up of 30.5 (10.5-50) months, all patients were alive with stable graft function and no disease recurrence. Conclusion: As shown in our series, an algorithmic approach to patient and treatment selection for LCH patients with liver involvement combined with newer chemotherapeutic agents and an optimized immunosuppression can result in excellent outcomes for a hitherto unfamiliar disease.
