Summary
A rare case of adult T-cell leukaemia lymphoma (ATLL) presented with small intestinal lymphoma in a Chilean patient. Early diagnosis and treatment led to a five-year disease-free survival, highlighting the importance of retroviral studies.
Area of Science:
- Oncology
- Virology
- Gastroenterology
Background:
- Adult T-cell leukaemia lymphoma (ATLL) is a rare malignancy associated with Human T-lymphotropic virus type 1 (HTLV-1).
- Primary gastrointestinal involvement as the initial presentation of ATLL is exceptionally uncommon.
Observation:
- A 25-year-old Chilean patient presented with primary small intestinal lymphoma, later evolving into a leukaemic phase.
- Duodenal biopsy revealed pleomorphic lymphoid cells (CD45RO+, CD20-) and circulating T-cells (CD2+, CD3+, CD4+, CD8-, CD25+, HLA-Dr+).
- HTLV-1 serology was positive, and HTLV-1 sequences were detected via PCR in tissue samples.
Findings:
- The patient achieved a five-year disease-free status following chlorambucil treatment.
- This case underscores the potential for ATLL to manifest initially as intestinal lymphoma.
Implications:
- In HTLV-1 endemic areas, retroviral studies are crucial for diagnosing T-cell lymphomas presenting in the intestine.
- Prompt diagnosis and treatment can lead to favorable outcomes even in rare presentations of ATLL.
