Insights
A cat diagnosed with chronic myelomonocytic leukemia (CMMoL) showed signs of feline leukemia virus (FeLV) infection. This feline leukemia diagnosis highlights similarities to human myelodysplastic syndrome (MDS).
Area of Science:
- Veterinary Medicine
- Hematology
- Oncology
Background:
- Feline leukemia virus (FeLV) is a significant pathogen in cats.
- Myelodysplastic syndromes (MDS) are a group of clonal hematopoietic stem cell disorders.
Observation:
- A 1-year-old cat presented with anorexia and weight loss.
- Hematologic findings revealed nonregenerative anemia, neutropenia, and monocytosis.
- Bone marrow smears showed dysgranulopoiesis with increased blast cells.
Findings:
- The cat tested positive for feline leukemia virus (FeLV) antigen.
- Diagnosis of chronic myelomonocytic leukemia (CMMoL) was established based on blood and bone marrow findings.
- The feline CMMoL case may represent a subtype analogous to human myelodysplastic syndrome (MDS).
Implications:
- This case underscores the importance of considering FeLV in cats with hematologic abnormalities.
- Feline CMMoL may serve as a model for studying human MDS.
- Further research into feline leukemia and related myelodysplastic disorders is warranted.
Abstract:
A 1-year-old spayed domestic short-haired cat was referred with anorexia and weight loss. Hematologic findings indicated nonregenerative anemia, severe neutropenia and monocytosis. The feline leukemia virus (FeLV) antigen test was positive reaction by enzyme-linked immunosorbent assay. Dysgranulopoiesis with slight increase in blast cells were observed in bone marrow smears. On the basis of blood and bone marrow findings, the cat was diagnosed as chronic myelomonocytic leukemia (CMMoL), which possibly corresponds to a kind of the subtypes in human myelodysplastic syndrome (MDS).
