Summary
Systemic mastocytosis, a rare disorder, can affect the jawbone. This case highlights the first documented instance of mastocytosis involving oral-maxillofacial bone, emphasizing diagnostic and management strategies.
Area of Science:
- Hematology
- Oncology
- Oral and Maxillofacial Surgery
Background:
- Systemic mastocytosis (SM) is a rare clonal disorder of hematopoietic stem cells characterized by mast cell accumulation in various tissues.
- Typically, SM involves the skin and bone marrow, but extraskeletal manifestations can occur.
- Oral-maxillofacial bone involvement in SM is exceptionally rare, with limited documented cases.
Observation:
- A patient presented with a mandibular lesion, initially without other bone lesions detected on scintigraphy.
- Radiographic monitoring over six months revealed the emergence of an osteolytic jaw lesion.
- Histologic and electron microscopic examination confirmed the diagnosis.
Findings:
- This report details the first documented case of systemic mastocytosis involving an oral-maxillofacial bone, specifically the mandible.
- The lesion demonstrated radiographic evidence of osteolysis.
- Biopsy confirmed mast cell infiltration consistent with systemic mastocytosis.
Implications:
- This case underscores the importance of considering rare diagnoses like systemic mastocytosis in patients with unexplained oral-maxillofacial bone lesions.
- Thorough preoperative evaluation and careful clinical management are crucial to prevent life-threatening complications associated with SM.
- Further research into the presentation and management of SM in the oral-maxillofacial region is warranted.
