B21: Human immunodeficiency virus [HIV] disease resulting in malignant neoplasms

B21.2: HIV disease resulting in other types of non-Hodgkin lymphoma

HIV disease resulting in other types of non-Hodgkin lymphoma, coded as B21.2 in the ICD-10 WHO 2016 classification, is a specific condition where the Human Immunodeficiency Virus (HIV) - an infection that weakens the immune system - leads to the development of a variant of non-Hodgkin lymphoma, a type of blood cancer. This lymphoma is not one of the common types, but a different form that still affects the body's lymph system, a part of the immune system. Symptoms can include fatigue, fever, weight loss, night sweats, and swollen lymph nodes. HIV weakens the body's ability to fight infection and disease, potentially leading to this type of lymphoma. Progression of this condition varies widely, as it depends on the specific type of non-Hodgkin lymphoma, the individual's health, and response to treatment.
