Overview
Based on both the clinical presentation and laboratory findings, adult T-cell leukemia may be classified into either an acute variant, chronic variant, smoldering variant, or an adult T-cell lymphoma variant.
Classification
- Based on both the clinical presentation and laboratory findings, adult T-cell leukemia may be classified into either an acute variant, chronic variant, smouldering variant, or an adult T-cell lymphoma variant.[1][2]
- The table below lists the adult T-cell leukemia clinical classification details:
| Clinical Variant | Description |
|---|---|
| Acute adult T-cell leukemia |
|
| Chronic adult T-cell leukemia |
|
| Smoldering adult T-cell leukemia |
|
| Adult T-cell lymphoma |
|
