ABSTRACT

BACKGROUND: Corneal epithelium remodeling in response to changes in the anterior corneal surface (keratoconus, corneal refractive surgery) is well-documented in the literature. However, several conditions may induce a different behavior of the epithelium, in which focal areas of epithelial thickening induce irregular astigmatism. This case report presents a highly unusual case of irregular astigmatism induced by an epithelial hyperplasia of unknown etiology, which was treated by the mechanical removal of only the epithelium. CASE PRESENTATION: A 29-year-old woman underwent implantable collamer lens implantation to correct myopia. The patient provided written informed consent. The procedure was uneventful in both eyes. Twenty months later, she complained of decreased visual acuity in the left eye (uncorrected distance visual acuity (UCDVA) was 20/30; corrected distance visual acuity was 20/20 with + 1.00 -2.25 × 170). Corneal topography revealed a nasal steepening in the left eye. Although the corneal thickness map was normal, epithelial thickness mapping revealed a localized nasal area of epithelial hyperplasia in the left eye that matched the area of steepest curvature. Slit lamp examination showed a total clear cornea with no signs of abnormality. The patient´s medical history was unremarkable and a case of epithelial hyperplasia of unknown etiology, without active inflammation, was considered. The decision was made to perform a mechanical removal of the corneal epithelium after application of diluted alcohol. One month after the procedure, the topography of the epithelized cornea showed a regular bow tie pattern and UCDVA improved to 20/20. No recurrence of the epithelial hyperplasia was detected after twenty-one months. CONCLUSIONS: Focal epithelial hyperplasia may induce irregular astigmatism. Epithelial thickness mapping is a very helpful technological tool to assess cases with irregular topography. De-epithelization as an isolated procedure may be useful for the successful management of these cases. Further research is required to understand the mechanism that triggers the spontaneous development of a focal epithelial hyperplasia.

ABSTRACT

El fibroma ameloblástico es un tumor odontogénico mixto benigno de rara aparición, que constituye el 2% de todos los tumores odontogénicos, es de crecimiento lento, más común en niños y adultos jóvenes, compuesto por tejido conjuntivo fibroso embrionario y epitelio odontogénico primitivo, se caracteriza por la proliferación de tejido epitelial y mesenquimático. Aparece con más frecuencia en la mandíbula en zona de molares y premolares de pacientes jóvenes sin predilección de sexo, asociándose a veces a un diente incluido. El presente artículo tiene como objetivo describir un caso clínico de un paciente en la segunda década de vida, con aparente anodoncia en el maxilar superior, que se encontraba asintomático y en el cual fue diagnosticado fibroma ameloblástico en maxilar superior, zona de incisivos anteriores, lado izquierdo, se realiza una breve revisión de la literatura y diagnósticos diferenciales, se analizan sus características clínicas e histológicas y la actitud terapéutica a tomar. El tratamiento quirúrgico conservador con extirpación seguida de curetaje parece ser la opción terapéutica más adecuada, y teniendo presente que el porcentaje de recidiva es del 18,3% principalmente debido a escisión incompleta de la lesión, se deben realizar controles radiográficos postoperatorios 6 meses después y cada año por los siguientes 5 años (AU)


The ameloblastic fibroma is a benign mixed, rare odontogenic tumour, which accounts for 2% of all odontogenic tumours. It is slow growing, and more common in children and young adults. It is composed of embryonic fibrous connective tissue and early odontogenic epithelium, and characterised by the proliferation of epithelial and mesenchymal tissue. It appears most frequently in the jaw area of molars and premolars of young patients with no sex predilection, and is sometimes associated with an impacted tooth. This article aims to describe a clinical case of a child in the second decade of life, with apparent anodontia in the maxilla, which was asymptomatic and later diagnosed as an ameloblastic fibroma in the left side maxilla incisors area. A brief review of the literature and differential diagnoses was carried out, including an analysis of its clinical and histological features, and the therapeutic approach to take. Conservative surgical excision followed by curettage seems to be the most appropriate treatment option. It should be noted that the recurrence rate is 18.3%, mainly due to incomplete excision of the lesion. Radiographic controls should be performed six months postoperatively, and every year for the following five years (AU)

ABSTRACT

Diabetes mellitus is one of the chronic systemic disorders with major influences of the oral cavity microenvironment. Oral manifestations of diabetes are diverse; they are represented by candidose, lichen plan, recurrent aphthous stomatitis, gingivitis, salivary disorders, oral mucosa atrophy and rarely hypertrophy; a possible link between oral cancer and diabetes is suspected, both in animal models and humans. We report a case of a young woman with type 1 diabetes with class I Kennedy edentation with mobile denture prosthesis; latter in the clinical follow-up, a hyperplasic lesion of the oral mucosa with p53 expression within the epithelial nuclei was identified, p53 being the more likely pathogenic pathway involved in diabetes-related oral cancer. The approach of this patient required multidisciplinary investigations and careful follow-up.

ABSTRACT

La hiperplasia epitelial focal (HEF) es una proliferación benigna de la mucosa oral con características clínicas e histológicas bien definidas. Se ha asociado a la infección de la mucosa oral por los tipos 13 y 32 del virus del papiloma humano (VPH) y, con menor frecuencia, a otros tipos. Su evolución clínica es variable, aunque suele persistir durante unos meses o años. Se han descrito de resolución espontánea y otros de persistencia prolongada. Se presenta el caso de un niño ecuatoriano que consultó por unas lesiones en la mucosa oral compatibles con el diagnóstico de HEF, que fueron confirmadas en el estudio histológico y en las que se identificó ADN del VPH tipo 13


Focal epithelial hyperplasia (FEH) is a benign proliferation of the oral mucosa with well defined clinical and histological characteristics. It has been associated with infection of the oral mucosa by types 13 and 32 of the human papillomavirus (HPV), and to a lesser extent, with other types. Its clinical course is variable, although it usually persists for months or years; cases with spontaneous resolution have been described, as have others with prolonged persistence. We present the case of an Ecuadorian boy whose visit was motivated by lesions in the oral mucosa consistent with a diagnosis of FEH, which were confirmed in the histological study, and in which HPV type 13 DNA was identified

ABSTRACT

Objetivo: Realizar un análisis retrospectivo de los hallazgos radiológicos en lesiones no palpables detectadas por mamografía, que originan la indicación de biopsia quirúrgica con resultado histológico de mastopatía proliferativa con y sin atipia.Material y métodos: Se seleccionaron 421 mujeres con 429 biopsias con resultado histológico de mastopatía proliferativa con y sin atipia, procedentes de un total de 1.252 biopsias quirúrgicas en lesiones no palpables con resultado de benignidad en dos hospitales. En todas las pacientes se registró la edad, antecedentes personales y familiares de cáncer de mama, motivo de petición de la mamografía y signo radiológico que originó la indicación de biopsia quirúrgica.Resultados: En 347 mujeres con 354 biopsias, el diagnóstico fue de mastopatía proliferativa (hiperplasia epitelial) y en las 74 mujeres restantes, con 75 biopsias, de hiperplasia atípica, lo que representa el 28 por ciento y 6 por ciento, respectivamente, de las 1.252 biopsias con resultado de benignidad. De los 354 casos con diagnóstico histológico de hiperplasia epitelial y de los 75 casos con diagnóstico de hiperplasia atípica, en 221 (62 por ciento) y 45 (60 por ciento), respectivamente, el signo radiológico más frecuente que originó la indicación de biopsia fue un grupo de calcificaciones (p < 0,05). La distorsión parenquimatosa con o sin calcificaciones fue el segundo signo radiológico en frecuencia, mostrando en el estudio histológico una estrecha asociación de estos procesos proliferativos con la cicatriz radial.Conclusiones: Las calcificaciones son el hallazgo radiológico que más frecuentemente origina la indicación de biopsia quirúrgica por lesiones no palpables en pacientes con resultado de mastopatía proliferativa con y sin atipia (AU)
