Langerhans cell histiocytosis of the jawbone: A comprehensive review and report of a case with spontaneous regression

Langerhans cell histiocytosis (LCH) is a rare disease of unknown pathogenesis that involves clonal proliferation of Langerhans cells and can affect multiple human body systems. LCH’s presentation in the jaws is often mistaken for severe periodontal disease because of the bone loss pattern and attendant tooth mobility mimicking that of periodontal disease. The purpose of this article is to review the literature to highlight current diagnostic and therapeutic strategies for LCH in the jawbone. In addition, a case with spontaneous regression of an apparent isolated focal presentation of LCH in the mandible of a young man is presented. After performing a diagnostic biopsy, a conservative “wait and see” approach for treating LCH in jaws is suggested. Based on the available clinical evidence, monitoring of similar cases for a longer period is reasonable before drawing further conclusions.

Educational objectives

Upon completion of this course, the dental professional should be able to:

  1. Identify the dental and systemic clinical features of Langerhans cell histiocytosis
  2. Distinguish LCH from periodontal and endodontic lesions
  3. Describe the different modalities utilized for the management of involved teeth
  4. Identify the team members who should be involved in treating such cases
