ABSTRACT
The objective of this investigation was to assess the prevalence of oral lichen planus (OLP) in Moroccan patients infected with hepatitis C virus (HCV) from the Hepatology service of Ibn Sina University hospital of Rabat. The study group consisted of 149 patients with HCV infection. All patients with clinical features of OLP were submitted to the service of oral surgery for confirmation. Among the 149 HCV-infected patients of the study group, 35 patients had OLP which represents a prevalence of 23.5 percent. Two out of these 35 patients with OLP-HCV association had cutaneous lichen planus (CLP) as well. Our findings indicate that there is a significant association between OLP and HCV infection especially for reticular and erosive types of OLP.

El grupo de estudio consistió de 149 pacientes con infección por el VHC. Todos los pacientes con características clínicas de LPO se presentaron al servicio de cirugía oral para su confirmación. Entre los 149 pacientes infectados por VHC del grupo de estudio, 35 pacientes presentaban LPO, una prevalencia de 23,5 por ciento. Dos de estos 35 pacientes con LPO asociado al VHC tenían también liquen plano cutáneo (LPC). Nuestros hallazgos indican que existe una asociación significativa entre la LPO y la infección por el VHC, especialmente para los tipos de LPO reticular y erosivo.

Langerhans cell histiocytosis (LCH), previously known as histiocytosis X, is a rare, proliferative disorder in which the accumulation of pathologic Langerhans cells leads to local tissue infiltration and destruction. The incidence of LCH is estimated to be one case per 200,000 children per year. The role of the dentist is important in early and accurate evaluation, staging and diagnosis of LCH, because it may mimic more common diseases, such as juvenile periodontitis and osteomyelitis. There are multiple treatment options, but the response is unpredictable. The aim of this paper is to give a short, introductory overview on current diagnostic and treatment strategies for LCH in the oral and maxillofacial region and to present a case of LCH that mimicked juvenile periodontitis and was resolved following extraction of affected teeth. The history, radiological appearance, differential diagnosis, histopathology and treatment options for the patient are discussed.
