ORPHA:289666Disease
Also called PBL
What it is
A rare aggressive B-cell non-Hodgkin lymphoma characterized by neoplastic cells resembling B immunoblasts or plasmablasts with a CD20-negative plasmacytic phenotype. The tumor may occur in the oral cavity, the gastrointestinal tract, or other, predominantly extranodal, sites and is typically associated with immunodeficiency or -suppression. The tumor cells are EBV-positive in most cases. Patients often present with disseminated bone involvement. Paraproteinemia may also be detected. Prognosis is generally poor.

Orphanet records these for the broader condition rather than for this specific form. They are a starting point, not a figure for this subtype — subtypes often differ, and some are defined by being rarer than the condition they sit under.
ICD-10 codes
ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
