Summary
This study reports the first case of eosinophilic fasciitis in a patient with polycythemia vera. The rare association highlights potential links between myeloproliferative neoplasms and autoimmune conditions.
Area of Science:
- Hematology
- Rheumatology
- Oncology
Background:
- Polycythemia vera (PV) is a myeloproliferative neoplasm characterized by increased red blood cell mass.
- Myelofibrosis is a known complication of PV, involving bone marrow scarring.
- Eosinophilic fasciitis (EF) is a rare connective tissue disorder causing inflammation and fibrosis of the skin and subcutaneous tissues.
Observation:
- A 60-year-old woman with a history of PV post-splenectomy presented with increasing white blood cell counts.
- Cytogenetic analysis revealed trisomy 8 and 9, and bone marrow biopsy confirmed myelofibrosis.
- The patient subsequently developed symptoms of acute swelling and pain in her lower extremities.
Findings:
- Histological examination confirmed the diagnosis of eosinophilic fasciitis.
- This case represents the first documented instance of EF occurring in a patient with PV in the English literature.
- The co-occurrence suggests a potential, previously unrecognized association between these conditions.
Implications:
- This association warrants further investigation into potential shared pathogenetic mechanisms between PV and EF.
- Understanding this link may lead to improved diagnostic and therapeutic strategies for patients with PV.
- Further research could explore immune dysregulation in myeloproliferative neoplasms and their association with autoimmune diseases.
