摘要
A 47-year-old woman presented with a 2-month history of subcutaneous nodules, erythema, and fever. 18F-FDG PET images demonstrated inverted FDG uptake pattern corresponding to the subcutaneous lesion against lymph nodes. The specimen of the inguinal lesion showed massive infiltration of small lymphocytes in the adipose tissue with rimming adipocytes, whereas very few tumor cells infiltrated the lymph nodes. Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) was diagnosed. SPTCL normally shows quite interesting distribution of tumor cells, that is, lymph node involvement is usually absent. Therefore, this case highlighted the importance of the inverted accumulation pattern on FDG PET to suspect SPTCL.
