Summary
Human T-cell lymphotropic virus type I-associated adult T-cell leukemia/lymphoma (ATL) can present as a smoldering form. This case report describes the first instance of smoldering ATL in a US patient, highlighting its distinct presentation.
Area of Science:
- Oncology
- Virology
- Hematology
Background:
- Human T-cell lymphotropic virus type I (HTLV-1) causes adult T-cell leukemia/lymphoma (ATL).
- ATL typically presents with rapid onset, skin involvement, hypercalcemia, and lymphadenopathy.
- Conventional chemotherapy is often ineffective against aggressive ATL.
Observation:
- A smoldering form of ATL, characterized by prolonged skin manifestations, has been primarily reported in Japan.
- This report details a case of smoldering ATL in a patient from the United States.
- The patient presented with a long-term history of cutaneous involvement.
Findings:
- The case demonstrates that smoldering ATL can occur in the United States.
- This presentation differs from the typical fulminant course observed in most US cases.
- The diagnosis was associated with Human T-cell lymphotropic virus type I infection.
Implications:
- Recognizing the smoldering ATL subtype is crucial for accurate diagnosis and management.
- This finding expands the known geographic distribution of smoldering ATL.
- Further research is needed to understand the pathogenesis and treatment of smoldering ATL in diverse populations.
