Summary
Arsenic intoxication can mimic myelodysplastic syndromes, a rare but critical diagnosis. Early detection and treatment with British anti-Lewisite (BAL) can resolve hematological issues, though neurological symptoms may persist.
Area of Science:
- Toxicology
- Hematology
- Internal Medicine
Background:
- Myelodysplastic syndromes (MDS) are a group of clonal hematopoietic stem cell disorders.
- Differential diagnosis of MDS can be challenging, especially in atypical presentations.
Observation:
- A 41-year-old woman presented with a 6-month history of gastrointestinal and neurological symptoms, along with pancytopenia.
- Bone marrow aspirate showed dysmyelopoietic changes across all cell lines.
- Urine analysis revealed significantly elevated arsenic levels.
Findings:
- The patient was diagnosed with arsenic intoxication presenting as MDS.
- Treatment with British anti-Lewisite (BAL) led to the resolution of gastrointestinal and hematological abnormalities.
- Neurological complications, however, continued to progress despite treatment.
Implications:
- This case highlights the importance of considering heavy metal intoxication, specifically arsenic, in the differential diagnosis of myelodysplastic syndromes.
- Atypical clinical features accompanying hematological abnormalities warrant thorough investigation for environmental or toxic exposures.
- Prompt identification and chelation therapy can improve hematological outcomes in arsenic-induced MDS.
