ABSTRACT
Lichen sclerosus is a chronic inflammatory mucocutaneous disease, rarely involving the mouth. There are only 20 well-documented cases of oral lichen sclerosus reported in the English-language literature. This report describes the clinicopathological features of 6 cases of oral lichen sclerosus; 5 in women. There were 12 lesions, mainly on the lips (50%) and buccal mucosa (25%). The affected areas appeared as irregular whitish patches, harder than the surrounding tissue. Half of the patients were symptomatic and presented with no associated skin and/or genital lesions. All cases were biopsied, and histopathological features were evaluated using hematoxylin-eosin and Verhoeff's stains, S-100 immunohistochemical reaction and transmission electron microscopy. Management of the oral lesions consisted of surgical excision, intralesional triamcinolone acetonide, oral colchicine, and regular follow-up. There is no effective curative treatment, but there are some options for patient management; and colchicine may be considered an additional choice.

Mandibular torus fracture as a result of accidental trauma has not been reported to date in the dental literature. This study describes the case of a young adult male who suffered multiple fractures affecting the teeth and mandibular torus secondary to chin area trauma due to a bicycle accident; the first manifestation of bone damage being left unilateral paraesthesia of the lip. An occlusal x-ray study of the affected area was made to evaluate possible fracture, as unlike centred periapical x-rays and orthopantomography, it is able to reveal the existence of a fracture line of the alveolar wall. In the associated presence of paraesthesia, a computed tomographic study is advisable.

La hiperplasia fibrosa es una lesión exofítica circunscrita y formada por tejido conectivo fibroso denso, cubierto por un epitelio escamoso estratificado. Se localiza con más frecuencia en la mucosa yugal, encía, lengua y paladar blando, generalmente zonas donde se produce mayor roce, ya que su etiopatogenia parece estar relacionada con factores irritativos crónicos o traumáticos repetidos. El tratamiento consiste en la extirpación quirúrgica y la eliminación de los factores irritantes locales. Presentamos un caso de tumoración unilateral de aspecto fibroso de diez años de evolución localizada en mucosa yugal izquierda, que incluía la carúncula de desembocadura del conducto de Estenon. El tratamiento consistió en la canalización del conducto para preservar su integridad, extirpación quirúrgica de la lesión con bisturí frío y colocación de un drenaje activo intraoral. El estudio histopatológico de la muestra confirmó el diagnóstico de hiperplasia fibrosa. Tras un año de seguimiento, el paciente no ha presentado ninguna recidiva, y el drenaje de la glándula parótida izquierda se mantiene normal (AU)
The fibrous hyperplasia is an exofitic injury circumscribed and formed by dense fibrous conective weave, covered by epithelio squamous stratified. lt is located with more frequency in the buccal mucosa, gingiva, tongue and soft palate, generally zones where greater rubbing takes place, since his etiopathogenia seems to be related to chronic irritatives or traumatic repeated factors. The treatment is based in the surgical extirpation and the elimination of the local irritating factors. We present a case of unilateral tumor of fibrous aspect of ten years of evolution located in left buccal mucosa, that included caruncula of opening of Estenon's duct. The treatment consisted of the canalization of the duct to preserve its integrity, surgical extirpation of the injury with cold scalpel and positioning of an active intraoral drainage. The histopathologic study of the sample confirmed the diagnosis of fibrous hyperplasia. After one year follow-up, the patient has not presented any recurrence, and the drainage of the left parotid gland is functioning normally (AU)
