Abstract
Langerhans cell sarcoma is a rare neoplastic proliferation of Langerhans cells with a poor prognosis. We report FDG PET/CT findings of Langerhans cell sarcoma in the left forearm of a 77-year-old woman who presented with progressive enlargement of the left forearm mass for over 2 months. 18 F-FDG PET/CT demonstrated a high FDG uptake by the mass along with several FDG-avid enlarged lymph nodes in the left arm and axilla. Pathology examination of the biopsied specimen from the left forearm mass led to a diagnosis of Langerhans cell sarcoma.
