Localized Leishmaniasis of the oral mucosa. A report of three cases.

The term leishmaniasis comprises a group of diseases caused by different species of a protozoon called Leishmania. Leishmaniasis is found worldwide, and is considered to be endemic in 88 countries. There are three main clinical forms of leishmaniasis: visceral leishmaniasis, cutaneous leishmaniasis and mucocutaneous leishmaniasis. Exclusive involvement of the mucosa is very rare. We present a series of three cases of mucosal leishmaniasis located in the oral cavity. The fact that all three cases were recorded in Spain (an area where L. infantum is endemic), suggests that the latter was the causal agent. The only manifestation of leishmaniasis disease in the described cases was the appearance of an oral lesion. Treatment was provided in the form of meglumine antimoniate in two patients, with a favorable response. One of the patients left the hospital after diagnosis, without receiving treatment, and the subsequent course is not known. A review is made of the literature on the subject.

Gingival neurofibroma in a neurofibromatosis type 1 patient.

Neurofibroma is a benign peripheral nerve sheath tumour. It is one of the most frequent tumours of neural origin and its presence is one of the clinical criteria for the diagnosis of type 1 neurofibromatosis (NF-I). Neurofibromatosis type 1 is an autosomal dominantly inherited disease due to an alteration in the long arm of chromosome 17. About 50% of NF-I patients have no family history of the disease. NF-I patients have skin lesions (cafe au lait spots and neurofibromas) as well as bone malformations and central nervous system tumours. Diagnosis is based on a series of clinical criteria. Gingival neurofibroma in NF-I is uncommon. Treatment of neurofibromas is surgical resection. The aim of this paper is to report a case of NF-I with gingival involvement and to review the literature.

Localized leishmaniasis of the oral mucosa. A report of three cases

El término leishmaniasis comprende un grupo de enfermedades causadas por diferentes especies de un protozoo llamado Leishmania. La leishmaniasis se produce en todo el mundo, considerándose endémica en 88 países. Existen tres formas clínicas principales de leishmaniasis: leishmaniasis visceral, leishmaniasis cutánea y leishmaniasis mucocutánea. La afectación de la mucosa, de manera exclusiva, por la Leishmania es muy rara. Presentamos una serie de tres casos de leishmaniasis mucosa localizados en la cavidad oral. El hecho de que todos los casos se produjeran en España, área endémica de L infantum, nos hace presuponer que éste fue el agente causal. La única manifestación de enfermedad de leishmaniasis en los casos descritos, fue la aparición de una lesión oral. Se administró tratamiento con antimoniato de meglumina en dos de ellos, respondiendo favorablemente. Uno de los pacientes abandonó el hospital tras el diagnóstico sin recibir tratamiento y se desconoce la evolución. Realizamos también una revisión de la literatura

Gingival neurofibroma in a neurofibromatosis type 1 patient. Case report

El neurofibroma es un tumor benigno, de los nervios periféricos, desarrollado a partir de la vaina neural. Representa uno de los tumores de origen neurógeno más frecuente y es uno de los criterios clínicos de diagnóstico de neurofibromatosis tipo 1 (NF-I). La NF-I es una enfermedad genética producida por una alteración en el brazo largo del cromosoma 17. La mitad de los casos tienen antecedentes familiares y el 50% son mutaciones nuevas. Los pacientes con NF-I principalmente presentan lesiones en la piel (manchas “café con leche” y neurofibromas), así como malformaciones óseas y tumores del sistema nervioso central. El diagnóstico de la enfermedad se basa en una serie de criterios clínicos. La aparición de neurofibromas en la encía en pacientes con NF-I es poco común El tratamiento de los neurofibromas es la escisión quirúrgica. El objetivo de este artículo es presentar un caso de NF-I con afectación neurofibromatosa de la encía maxilar, diagnosticado y tratado quirúrgicamente en nuestro Servicio de Cirugía Oral y Maxilofacial y realizar una revisión de la literatura
