The correlation between SUVmax of the lesions in the subcutaneous adipose on 18F-FDG PET/CT scan and the expression of Ki-67 of the lesions in the subcutaneous adipose on immunohistochemistry was calculated by linear regression analysis, which revealed no significant correlation between them in patients with SPTCL (r = 0.19, P > 0.05) (Figure 7). The gene discussed is MKI67; the disease is subcutaneous panniculitis-like T-cell lymphoma.
