F-18 FDG uptake in subcutaneous panniculitis-like T-cell lymphoma.
A 41-year-old male presented to an outside institution complaining of a lump under the skin of his right abdomen. CT scan reported ill-defined densities with streaky inflammatory changes in the anterior abdominal wall. Excisional biopsy of the subcutaneous adipose tissues of the right anterior abdominal wall was consistent with subcutaneous panniculitis-like T-cell lymphoma. Flow cytometry demonstrated CD3+ and CD8+ population. On immunohistochemistry, most lymphoid cells were positive for CD3, CD45RO, CD5, and CD8 and negative for CD10, CD43, CD4, CD20, and CD56. The MIB-1 proliferative index was 30%. Bone marrow biopsy revealed no evidence of lymphomatous involvement.
