The left panel shows a P E T slash C T image with increased F D G uptake in the right lumbar dorsal region, indicated by focal hypermetabolic activity. The right panel displays a hematoxylin and eosin (H and E)-stained tissue section showing adipose tissue infiltrated by lymphocytes (scale bar: 50 micrometers).
Imaging findings of subcutaneous panniculitis-like T cell lymphoma in P3. The FDG-PET scan demonstrated hyperaccumulation in the right lumbar dorsal region (left panel). The right panel shows HE stains of the tumor, with infiltrating lymphocytes identified as CD3+ (CD8+ > CD4+), TIA-1+, perforin+, ganzyme B+, and EBER−.
