Summary
A patient initially diagnosed with megakaryocytic myelosis was found to have reactive thrombocytosis due to severe tuberculosis. This case highlights the importance of considering infections in differential diagnoses for myeloproliferative disorders.
Area of Science:
- Hematology
- Infectious Diseases
- Pathology
Background:
- A 66-year-old female presented with weight loss and fatigue, exhibiting thrombocytosis and leukocytosis.
- Initial bone marrow examination showed increased megakaryocytes, suggesting megakaryocytic myelosis.
Observation:
- The patient underwent busulfan chemotherapy for suspected megakaryocytic myelosis.
- Sepsis developed during treatment, ultimately proving fatal.
- Autopsy revealed disseminated caseous tuberculosis (septic tuberculosa gravissima).
Findings:
- Bone marrow was atrophic, and lymphoid organs showed no myeloproliferative disorder.
- The initial diagnosis was revised to megakaryocytic pseudomyelosis, a reactive thrombocytosis secondary to tuberculosis.
Implications:
- This case underscores the critical need to differentiate reactive thrombocytosis from myeloproliferative neoplasms.
- Infections, particularly tuberculosis, can mimic myeloproliferative disorders, necessitating thorough etiological investigation.
- Accurate diagnosis is crucial for appropriate patient management and treatment strategies.
