This category probably encompasses several biological subgroups that are still undefined. Because PTCL, NOS is a diagnosis of exclusion, it requires an expert pathologic review with an exhaustive workup. A recent study highlighted that the diagnosis of PTCL, NOS is challenging and poorly reproducible, with an overall concordance of 63.4% between referral and expert pathologists.
