Summary
A rare case of Langerhans cell histiocytosis (LCH) affecting the mandible is presented. Diagnosis was confirmed through histopathology and immunohistochemistry in a 34-year-old woman with jaw pain and pyorrhea.
Area of Science:
- Oral pathology
- Histiocytosis
- Oncology
Background:
- Langerhans cell histiocytosis (LCH) is a rare clonal proliferative disorder of Langerhans cells.
- Mandibular involvement of LCH is uncommon, presenting diagnostic challenges.
Observation:
- A 34-year-old female presented with a year of left mandibular gingival pain and two months of pyorrhea.
- Clinical presentation mimicked common dental pathologies.
Findings:
- Histopathological examination revealed characteristic Langerhans cell morphology.
- Immunohistochemical analysis confirmed the presence of CD1a and S100 protein, consistent with LCH.
Implications:
- This case highlights the importance of considering LCH in the differential diagnosis of persistent mandibular lesions.
- Early and accurate diagnosis is crucial for appropriate management of Langerhans cell histiocytosis.
