Lysosomal enzyme abnormalities in preleukaemic Sweet's disease: case report
Journal of Clinical Pathology
|January 1, 1987
Summary
Biochemical analysis of marrow enzymes detected abnormalities suggestive of acute myeloid leukemia in a patient with Sweet's disease one year before her leukemia diagnosis. This suggests enzyme testing may identify high-risk patients.
Area of Science:
- Hematology
- Oncology
- Biochemistry
Background:
- Sweet's disease is an inflammatory condition that can be associated with hematologic abnormalities.
- Preleukaemic conditions can precede the development of acute myeloid leukemia (AML).
- Lysosomal enzymes play a role in cellular function and their abnormalities can indicate disease states.
Observation:
- A patient with Sweet's disease and monocytosis exhibited quantitative and qualitative abnormalities in marrow lysosomal enzymes.
- These enzymatic abnormalities were detected 12 months prior to the patient's presentation with acute myelomonocytic leukemia (AMML).
Findings:
- The observed lysosomal enzyme abnormalities in marrow cells were indicative of acute myeloid leukemia.
- The findings suggest a potential preleukaemic state in this patient.
Implications:
- Biochemical characterization of blood and marrow cell extracts may serve as an early diagnostic tool.
- Identifying patients with Sweet's disease and other preleukaemic conditions at high risk for developing leukemia is crucial for timely intervention.
- This approach could lead to earlier diagnosis and management of leukemia in at-risk individuals.
