Definitions
| Tumours of haematopoietic and lymphoid tissues | ||
| ICD-O-3 topography code: | C42 and C77 | |
A condition characterized by proliferation of lymphocytes at various stages of differentiation. Lymphoproliferative disorders can be neoplastic (clonal, as in lymphomas and leukemias) or reactive (polyclonal, as in infectious mononucleosis). This is not a specific disease, and is a descriptive term, rather than a diagnosis.
