Subcutaneous panniculitis-like T-cell lymphoma (SCPTCL) is a rare subtype of peripheral T-cell lymphoma. This case report is of a 24-years-old man presented with subcutaneous nodules on his lower abdomen and buttocks. An abdominal CT revealed multiple nodules and increased streaky densities in the subcutaneous fat layer of the abdominal wall and buttocks. In addition, multiple focal FDG uptake lesions of the subcutaneous fat layer were detected from a ^18FFDG PET/CT and the histologic diagnosis determination was SCPTCL. We report here one case of SCPTCL, determined by the CT and ^18FFDG PET/CT imaging features and a review of the relevant literature.
