We present a rare manifestation in a male patient, 51 years old, with clinical and radiographic examinations presenting a pathological fracture of the mandible on the right side (Figure 1), due to a radiolucent lesion of approximately 2.5cm, that was circumscribed and well delimited, and the presence of another lesion in the symphysis region that was approximately 0.5cm in diameter.
Histological exam. (A) Eosin and hematoxylin; (B-C) Positive reaction to immunohistochemistry by CD-1a, CD207 (Langerin) and Protein S100.

The histological finding was consistent with the infiltration of Langerhans cells, macrophages, lymphocytes, eosinophils, granulocytes and giant cells, that positively reacted to immunohistochemistry for CD-1a, CD207 (Langerin) and Protein S100 (Figure 2A - C).
