A patient with Adult T-cell leukemia (ATL) and tuberculosis experienced ATL transformation during TB treatment. The patient ultimately succumbed to respiratory failure, complicated by leukemic cell infiltration and cytomegalovirus infection.
Area of Science:
- Oncology
- Infectious Diseases
- Pathology
Background:
- Adult T-cell leukemia (ATL) is a lymphoproliferative malignancy.
- Tuberculosis (TB) is a significant infectious disease caused by Mycobacterium tuberculosis.
- Co-infection of ATL and TB presents complex clinical challenges.
Observation:
- A 59-year-old male presented with cervical lymphadenopathy, liver and pancreatic masses, and lung nodules.
- Initial lymph node biopsy showed tuberculous bacilli without granuloma formation.
- Diagnosis of ATL was confirmed by atypical lymphocytes and positive serology.
Findings:
- Successful TB treatment with ethambutol, isoniazid, and rifampicin preceded ATL blastic transformation.
- Pulmonary infiltrates initially improved with chemotherapy and antibiotics but recurred.
- Autopsy revealed interstitial fibrosis, leukemic cell infiltration, and cytomegalovirus (CMV) infection in the lungs.
Implications:
- This case highlights the potential for ATL to transform during treatment for opportunistic infections like TB.
- The complex interplay between ATL, TB, and secondary infections (CMV) can lead to treatment resistance and poor outcomes.
- Understanding these interactions is crucial for managing immunocompromised patients with hematologic malignancies.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...
