Infiltration may refer to normal physiological processes, such as the infiltration of certain immune cells into peripheral tissues. Infiltration may also refer to pathological processes, such as malignant tumor cells infiltrating new areas of the human body, or small particles infiltrating tissues, where they may cause damage or inflammation.
Swollen gums due to infiltration by leukemia cells in a person with AML. Most signs and symptoms of AML are caused by the crowding out in bone marrow of space for normal blood cells to develop. [7] A lack of normal white blood cell production makes people more susceptible to infections. [8]
[1] [2] [3] [5] Although a diagnostic workup has not been finalized, the suggested diagnostic workup includes (1) confirming HIV infection, (2) confirming six or greater months of characteristic signs and symptoms, (3) evidence of organ infiltration by CD8+ T cells, and (4) exclusion of other autoimmune conditions.
Adrenal infiltration may be harder to appreciate given that its symptoms of orthostatic hypotension and low blood sodium concentration may be attributed to autonomic neuropathy and heart failure. [10] "Amyloid deposits occur in the pancreas of people who also have diabetes mellitus, although it is not known if this is functionally important.
Central nervous system (CNS) symptoms such as cranial neuropathies due to meningeal infiltration are identified in less than 10% of adults and less than 5% of children, particularly mature B-cell ALL (Burkitt leukemia) at presentation. [20] The signs and symptoms of acute lymphoblastic leukemia are variable and include: [21]
The disease may cause different symptoms and be caused by different processes in childhood as compared to adulthood. Some studies have shown that it is associated with either other medical conditions involving the esophagus, including gastroesophageal reflux disease and achalasia , or other inflammatory conditions such as Crohn's disease ...
Lymphangiomatosis can occur at any age, but the incidence is highest in children and teenagers. Signs and symptoms are typically present before the age of 20 and the condition is often under-recognized in adults. [2] It affects males and females of all races and exhibits no inheritance pattern.
Leukemia cutis is the infiltration of neoplastic leukocytes or their precursors into the skin resulting in clinically identifiable cutaneous lesions. [1] This condition may be contrasted with leukemids, which are skin lesions that occur with leukemia, but which are not related to leukemic cell infiltration.
