Summary
Systemic mastocytosis was diagnosed in a woman with prior sclerosing cholangitis, presenting with abdominal pain and organomegaly. Aggressive disease progression led to unsuccessful acute myeloid leukemia chemotherapy.
Area of Science:
- Hematology
- Gastroenterology
- Oncology
Background:
- Sclerosing cholangitis is a chronic liver disease characterized by bile duct inflammation and fibrosis.
- Systemic mastocytosis is a rare disorder involving abnormal mast cell proliferation in various organs.
Observation:
- A 43-year-old woman with a history of sclerosing cholangitis presented with fever, abdominal pain, hepatosplenomegaly, ascites, cholestasis, anemia, and thrombocytopenia.
- Initial diagnosis of sclerosing cholangitis was based on liver biopsy and ERCP.
- Bone marrow biopsy and antitryptase staining of liver biopsy revised the diagnosis to systemic mastocytosis.
Findings:
- The patient exhibited aggressive systemic mastocytosis.
- Treatment with an acute myeloid leukemia chemotherapy regimen was ineffective.
Implications:
- This case highlights the importance of considering systemic mastocytosis in patients with unexplained abdominal symptoms and liver disease.
- Accurate diagnosis through bone marrow biopsy and specific stains is crucial for appropriate management.
- The aggressive nature of the disease and lack of response to standard chemotherapy underscore the need for novel therapeutic strategies.
