Primary cytodiagnosis of peritoneal extramedullary hematopoiesis
Abstract:
Cytologic examination of peritoneal fluid in a patient with known myelofibrosis and previous splenectomy revealed megakaryocytes along with erythroid and myeloid precursors. These findings were consistent with extramedullary hematopoietic (EMH) implants of the peritoneum. A few similar cases have been occasionally reported in the literature. This case represents an additional example of a primary diagnosis of peritoneal EMH in which therapy was based on the cytologic findings and sequential cytologic observations were made.
Insights
Cytologic examination revealed extramedullary hematopoietic (EMH) implants in the peritoneum of a myelofibrosis patient. This case highlights peritoneal EMH as a primary diagnosis, managed and monitored via cytology.
Area of Science:
- Hematology
- Cytopathology
Background:
- Myelofibrosis is a bone marrow disorder characterized by fibrosis and extramedullary hematopoiesis.
- Splenectomy is a common procedure in managing myelofibrosis complications.
- Extramedullary hematopoietic (EMH) implants can occur in various organs, including the peritoneum.
Observation:
- Cytologic examination of peritoneal fluid was performed in a patient with known myelofibrosis and prior splenectomy.
- The examination revealed the presence of megakaryocytes, alongside erythroid and myeloid precursors.
Findings:
- The cytologic findings were consistent with extramedullary hematopoietic (EMH) implants within the peritoneum.
- This represents a rare instance of primary peritoneal EMH diagnosis.
- Therapy was guided by cytologic findings, with sequential monitoring.
Implications:
- This case adds to the limited literature on peritoneal EMH.
- Cytology serves as a crucial tool for diagnosing and monitoring peritoneal EMH.
- Understanding EMH patterns is vital for managing myelofibrosis patients post-splenectomy.
