Abstract: Abstract: A 24-year-old man with a history of hemophagocytic lymphohistiocytosis (HLH) presented with swelling of the left foot and skin ulcer. The patient received bone marrow transplantation for HLH 3 years ago for his HLH. Biopsy of left foot skin demonstrated primary cutaneous natural killer/T-cell lymphoma: a posttransplant lymphoproliferative disorder. FDG PET/CT images demonstrated multiple foci of abnormal accumulation in the body, especially in the skin. Follow-up PET/CT after chemotherapy demonstrated that most abnormal activities disappeared except for the lesion in the left foot.<br />Competing Interests: Conflicts of interest and sources of funding: J.Y. was supported by National Key Research and Development Plan (no. 2020YFC0122000), National Natural Science Foundation of China (no. 81771860, 81971642), Beijing Natural Science Foundation (no. 7192041).
