Resumo: Langerhans cell histiocytosis (LCH) is a rare disorder characterized by abnormal proliferation and infiltration of histiocytic cells. The jawbones are involved in about 20-30% of all skeletal cases. A 27-year-old female patient presented multiple lesions in the maxilla and mandible from 2012 to 2021. Radiographically the lesions appear in a lytic form. An incisional biopsy was performed and confirmed the diagnosis of LCH, showing proliferation of large, round to oval mononuclear cells with an epithelioid shape, with eosinophilic cytoplasm and a grooved nucleus. The treatment adopted consisted in intralesional corticosteroid therapy, a surgical approach, and chemotherapy. The last recurrence was diagnosed 5 months ago and the patient is on the way to being submitted to another surgical treatment.
