Langerhans cell hystiocytosis mimicking necrotizing ulcerative periodontitis - A case report

Abstract

Langerhans cell histiocytosis (LCH) is a rare disease characterized by abnormal proliferation of bone marrow derived histiocytes followed by their deposition in tissues elsewhere in the body causing damage. Oral manifestations of LCH can sometimes be the only presenting symptoms or the first sign of a disseminated disease. Ulcerated lesions of oral mucosa are one of the common clinical manifestations and can help in early diagnosis of the disease when presented. Since the clinical features mimics several other diseases of oral and maxillofacial region it can be misdiagnosed easily as other pathologies. This article highlights the clinicopathological features of a case of LCH in an elderly patient who has reported to our outpatient department.
