ABSTRACT

La hiperplasia epitelial focal (HEF) o enfermedad de Heck es una patolog¡a poco frecuente de la mucosa oral, caracterizada por una proliferaci¢n benigna del epitelio debida a la infecci¢n por el papilomavirus humano (PVH) tipos 13 y 32. El nombre enfermedad de Heck deriva del nombre del m‚dico que evalu¢ al primer paciente, en M‚xico, en 1961. Sin embargo, una revisi¢n de la literatura latinoamericana revela publicaciones previas realizadas por Estrada, en 1956, quien observ¢ esta entidad en indios colombianos. Algunos a¤os despu‚s, Soneira y Fonseca realizaron la primera descripci¢n completa de la enfermedad, y se¤alaron sus caracter¡sticas cl¡nicas e histol¢gicas y, adem s, sugirieron el posible origen viral. Finalmente, en 1965, Archard y col. la denominaron HEF, aunque en la actualidad se sugiere utilizar el nombre de hiperplasia multifocal del epitelio, que describe mejor las caracter¡sticas cl¡nicas y microsc¢picas de la enfermedad. La HEF, aunque.


The focal epithelial hyperplasia (HEF) or Heck's disease is a rare disease of the oral mucosa, characterized by benign epithelial proliferation due to infection with human papillomavirus (HPV) ttypes 13 and 32. The disease name derives Heck the name of the doctor who evaluated the first patient in Mexico in 1961. However, a review of Latin American literature reveals previous publications by Estrada, in 1956, who observed this entity in Colombian Indians. Some years later, Soneira and Fonseca made the first complete description of the disease, noting their clinical and histological features and also suggested the possible viral origin. Finally in 1965, Archard et al. HEF called it, although at present it is suggested to use the name multifocal epithelial hyperplasia, which best describes the clinical and microscopic features of the disease. The HEF is presented with a clear predominance of Americans, Eskimos and Indians some communities in South Africa, although isolated cases in other ethnic groups. In South America it is more common in the Amazon basin of Peru, Venezuela, Colombia, Bolivia, Brazil and Paraguay.

ABSTRACT

La hiperplasia epitelial multifocal es una enfermedad benigna que se caracteriza por la presencia de múltiples pápulas en la mucosa de la cavidad bucal, asociada con el virus del papiloma humano 13 y 32. En el presente trabajo se describen tres casos con características clínicas similares, donde se evidencian múltiples pápulas no dolorosas localizadas en mucosa bucal y lengua, mostrando un curso lento y benigno las cuales no habían sido diagnosticadas previamente por dentistas de práctica general. Se llevó a cabo el diagnóstico basado en las características clínicas patognomónicas de las lesiones, historia familiar y evolución; se les dio información a los pacientes acerca de su padecimiento y se mantienen periódicamente en observación. El objetivo de este trabajo es mostrar las características clínicas de la hiperplasia epitelial multifocal y hacer una revisión de la literatura en cuanto a la etiología de las lesiones su evolución, diagnóstico diferencial y tratamiento.


Multifocal epithelial hyperplasia is a benign disease characterized by the presence of multiple papules in oral cavity mucosa. It is as-sociated with HPV 13 and 32. In this paper, we describe three cases with similar clinical features, involving the presence of multiple painless papules localized in the oral mucosa and on the tongue, and displaying a slow and benign course. The condition had not been previously diagnosed by general dental practitioners. We made our diagnosis based on the pathognomonic clinical features of the lesions, family history, and evolution of the condition. The patients concerned were provided with information about their disease and kept under regular observation. The aim of this article is to describe the clinical features of multifocal epithelial hyperplasia and present a review of the literature on the etiology of the lesions, their evolution, differential diagnosis, and treatment.

ABSTRACT

Background: Oral lesions caused by human papillomavirus (HPV), share morphological features which may complicate their diagnosis. Aim: To analyze the usefulness of Toki's morphological criteria for the diagnosis of HPV lesions in cervix, in the diagnosis of oral lesions. Materials and Methods: Retrospective study of 355 oral lesions by HPV. The pathologic evaluation was carried out three times by the same examiner with a Kappa coefficient of 0.780 (p = 0.01). Toki's criteria scored the presence of acanthosis as 1, dyskeratosis as 1, koilocytosis as 4, basilar hyperplasia as 1, bi or multinucleated cells as 2 and papillomatosis as 1. The information was analyzed using χ² and binary logistic regression. Results: Fifty eight percent of cases (207) corresponded to Verruca Vulgaris (VV), 23% (80) to Multifocal Epithelial Hyperplasia (MEH), and 19% (68) to Condyloma Acuminatum (CA). According to Toki's criteria, 76/80 MEH lesions, 195/207 of VV and 67/68 of CA, had a score equal or greater than six. A logistic regression showed that dyskeratosis suggests the presence of MEH. The presence of acanthosis and dyskeratosis in HPV oral lesions are not useful criteria for the diagnosis of VV. No significant associations with CA were found. Conclusions: The morphological criteria studied do not predict their possible viral etiology and do not allow a differential diagnosis of the lesions. Therefore, polymerase chain reaction studies are required to identify high-risk HPVs or sexually transmitted viral lesions.

ABSTRACT

La Hiperplasia Epitelial Focal es una patología que se caracteriza por la presencia de múltiples pápulas en la mucosa de la cavidad oral, producida por subtipos del papiloma virus humano 13 y 32, normalmente se presenta en niños y adolescentes, las lesiones se encuentran con mayor frecuencia en las mucosas labial, yugal y Iingual. Entre las diferentes alternativas de tratamiento se encuentra la quirúrgica, criocirugía, vitamina A, ablación con laser. El ácido tricloroacético es utilizado en el tratamiento de infecciones con virus del papiloma humano como condiloma, papiloma, verrugas vulgares en la mucosa vaginal arrojando buenos resultados presentándose resolución de las lesiones y mucosa vaginal en buen estado. Se reportan dos casos de pacientes femeninas pediátricas, remitida al servicio de estomatología y cirugía bucal de la universidad de Cartagena para el manejo y diagnóstico de múltiples lesiones en mucosa bucal. Se establece diagnóstico de hiperplasia epitelial focal y se decide implementar terapéutica con la aplicación de acido tricloroacético al 95%, observándose resolución de las lesiones con dos aplicaciones tópicas


Focal epithelial hyperplasia is a condition that is characterized by the presence of several papules on the oral cavity mucous membrane, It`s of viral etiology caused by human papilloma virus subtypes 13 and 32, usually occurs in children and adolescents rarely affects adults, injuries are more frequently found in the labial mucosa, buccal and Iingual. Among the various treatment alternatives include surgery, cryosurgery, vitamin A, laser ablation. Trichloroacetic acid is used in the treatment of infections with human papilloma virus as condyloma, papilloma, warts in the vaginal mucosa showing good results, successful resolution of the lesions and vaginal mucosa and in good condition. We report two cases of female patient, referred to the department of stomatologic and oral Surgery of Cartagena University for further management and diagnosis of multiple lesions in the oral mucosa. Diagnosis of focal epithelial hyperplasia is established and decided to implement therapeutic application of trichloroacetic acid 95%, observing resolution of lesions with two topical applications

ABSTRACT

Aim: To study oral hyperplastic epithelium, dysplastic epithelium and squamous cell carcinoma to determine (1) the prevalence of p53 protein immunoreactivity, (2) number of p53 positive cells, and (3) the area of localization of p53 protein immunoreactivity. Methods: Two contiguous sections from 30 tissue specimens (10 each from oral hyperplastic epithelium, dysplastic epithelium and squamous cell carcinoma) were subjected to hematoxylin and eosin (H/E) staining forhistopathological diagnosis and immunohistochemical (IHC) staining for demonstration of p53. p53 positivity was looked for in each IHC stained slide and the number of positive cells amongst 1,000 epithelial cells were recorded. The localization of these p53 positive cells within the strata (i.e.basal/suprabasal, spinous and superficial layers) of epithelium between 3 groups, and also with ineach group according to histological grades was recorded. Results: Higher p53 positive cell counts were demonstrated in oral squamous cell carcinoma compared to hyperplastic and dysplastic tissues. The expression of p53 in epithelial hyperkeratosis was mainly localized to basal epithelialcells whereas in epithelial dysplasia, it was predominantly localized to spinous epithelial cells. Conclusions: Qualitatively p53 is not a specific marker for malignancy of oral epithelium. However the quantitative analysis of p53 positive cells and their localization in oral epithelium is of importance as a marker for oral squamous cell carcinoma.

ABSTRACT

La Hiperplasia Epitelial Multifocal (HEM) es una enfermedad caracterizada por múltiples pápulas en la mucosa bucal. Ha sido reportada en indígenas, así como en grupos de esquimales y su etiología se relaciona a la infección por VPH. Las lesiones afectan principalmente niños y son de carácter autolimitado y benigno. Se realizó un estudio en seis comunidades indígenas pertenecientes a la etnia Pemón en la Gran Sabana Estado Bolívar en Venezuela, con el objetivo de determinar la presencia de HEM, caracterizar dicha enfermedad y finalmente tratarla. 250 niños fueron evaluados clínicamente en un rango de edades entre 3 y 13 años, de los cuales 18 presentaban HEM (7.2 por ciento). La enfermedad se presentó con predilección 2:1 por el sexo femenino en un promedio de 8 años de edad. Las lesiones fueron más frecuentes en los labios, del mismo color de la mucosa, aunque algunas mostraron una superficie blanquecina, posiblemente producto del roce o mordedura. El estudio histopatológico mostró características de HEM en todos los casos, incluyendo características consistentes con infección por VPH. Las lesiones fueron tratadas exitosamente con criocirugía


Multifocal epithelial hyperplasia (MEH) is a disease characterised by multiple papules on the oral mucosal. MEH has been reported in American Indigenous, as well as in Eskimos and its aetiology has been related to HPV infection. Lesions typically appear in children and show a limited and benign course. The present study was carried out in six Venezuelan Indigenous communities of Gran Sabana, Bolivar State. The aim of the study was to determine the presence of MEH, describe it and eventually treat the disease. 250 children were evaluated and 18 showed HEM features (7.2%). A female predilection was observed (2:1) and the mean of age was 8 years old. Lesions were the same colour of the mucosa or slightly whiter, probably due to chewing or trauma. Lips were more frequently affected. All cases showed histopathological characteristics of MEH, including features consistent with HPV infection. Patients were successfully treated by cryosurgery.

ABSTRACT

O objetivo deste trabalho é estabelecer a relação entre a infecção pelo vírus do papiloma humano (HPV) e o desenvolvimento de lesões malignas (carcinoma epidermóide) e benignas (hiperplasia epitelial papilomatosa e papiloma) de cavidade bucal e orofaringe. MÉTODOS: Estudo retrospectivo de 66 lâminas e blocos de parafina com tecido biopsiado e fixado com formalina. Esse material, colhido no ano de 2002, refere-se a uma casuística de 44 homens (66,7 por cento) e 22 mulheres (33,3 por cento) com idades que variavam entre 11 e 100 anos. O diagnóstico foi confirmado em 38 casos de carcinoma epidermóide, 20 casos de hiperplasia epitelial papilomatosa e oito casos de papilomas. Utilizamos a imunohistoquímica para analisar este material e determinar a possível presença do DNA viral nas amostras citadas. RESULTADOS: Detectamos a presença do DNA viral (HPV) em 16 dos 38 casos de carcinoma (42,5 por cento), 19 em 20 casos de hiperplasia (95 por cento) e em todos os oito casos de papilomas (100 por cento). CONCLUSAO: Este estudo demonstrou que as lesões papilomatosas e hiperplásicas da boca e orofaringe estão associadas ao HPV, ao contrário do carcinoma espinocelular que não apresentou correlação estatística significante com este agente infeccioso.
