Insights
Central diabetes insipidus (DI) can be an early indicator of acute myeloid leukemia (AML). This case highlights a rare association between AML with a t(3;12) translocation and DI.
Area of Science:
- Hematology
- Endocrinology
Background:
- Acute myeloid leukemia (AML) is a heterogeneous hematologic malignancy.
- Central diabetes insipidus (DI) is characterized by inadequate antidiuretic hormone secretion.
Observation:
- A 52-year-old woman presented with polyuria and polydipsia, indicative of central DI.
- The central DI was the initial clinical manifestation of AML.
Findings:
- Cytogenetic analysis revealed a novel balanced translocation, t(3;12)(q26;p12), in the AML cells.
- The patient experienced disease relapse and deep venous thrombosis despite initial chemotherapy and vasopressin treatment.
Implications:
- This case represents the first reported association between AML with the t(3;12) translocation and central DI.
- Understanding the pathogenesis of DI in AML is crucial for early diagnosis and management.
- Further research into rare AML-DI associations may reveal new diagnostic and therapeutic strategies.
Abstract:
A 52-year-old woman presented with polyuria and polydipsia. A diagnosis of central diabetes insipidus (DI) was made, which turned out to be the first sign of acute myeloid leukemia (AML). Cytogenetic analysis revealed a balanced translocation between chromosome 3 and 12 t(3;12)(q26;p12). The patient was treated with standard induction chemotherapy and vasopressin. Before consolidation chemotherapy could be administered, deep venous thrombosis was diagnosed and leukemia relapsed. Rescue chemotherapy was started. This is the first report of an association between AML with t(3;12) and DI. Its possible pathogenesis is discussed with a review of the literature.
