Non-bolded entities represent malignancies in humans only whereas bolded entities reflect malignancies reported in both humans and canines. * A neoplasm with an EATL-like morphology has been described in dogs, but an association with celiac disease has not been documented. ** In humans, TZL is considered a morphologic variant of PTCL, NOS.
