Oral Langerhans Cell Histiocytosis in Two Pediatric Patients.
Journal of dentistry for children (Chicago, Ill.)(2021)
摘要
We report two cases of Langerhans cell histiocytosis (LCH) in the oral cavity of children. An 11-month-old girl was referred for evaluation of a nodular and sessile lesion in the alveolar ridge covering the primary left mandibular central incisor. The second patient was a seven-year-old boy with an ulcerated lesion in the gingiva covered by necrotic areas, extending to the sulcus of the vestibule. The patients underwent incisional biopsies and histopathological exams showed a proliferation of Langerhans and eosinophil cells, suggesting a diagnosis of LCH, which was confirmed by positive immunohistochemical expression of S100 and CD1.
