Abstrakt: Langerhans cell sarcoma (LCS) is a rare high-grade neoplasm of langerhans cell phenotype having unambiguous malignant cytological features. We report such a rare case in a 20-year-old man who presented with dyspnea and high-grade fever. On evaluation, he had generalized lymphadenopathy, hepatosplenomegaly, and a large anterior mediastinal mass. Fine needle aspiration from the mediastinal mass and bone marrow aspirate showed numerous atypical cells, many of which showed grooved nuclei. In addition, the bone marrow showed prominent hemophagocytosis. The patient had a stormy hospital stay and succumbed to the illness. The autopsy revealed a rare multisystem involvement by LCS involving the lymph nodes, liver, spleen, lungs, and intestine, which harbored a BRAFV600E mutation and was associated with hemophagocytosis.
