ABSTRACT
Introdução: a hiperplasia epitelial focal (HEF) ou doença de Heck, caracteriza-se por ser uma lesão benigna rara da mucosa bucal. Geralmente, está associada a proliferação do epitélio pavimentoso atribuída principalmente ao papiloma vírus humano (HPV) dos subtipos 13 e 32. Objetivo: relatar o caso de um paciente, com suspeita diagnóstica de HEF, descrever suas manifestações clínicas bucais e histopatológicas. Metodologia: homem, 38 anos, melanoderma, compareceu no Serviço Universitário com queixa de ardência em mucosa bucal. Ao exame clínico, apresentava múltiplas lesões papulares, firmes à palpação, de coloração rósea, com pápulas aglomeradas ou isoladas, localizadas em rebordo alveolares, gengiva inserida e livre da arcada superior e inferior, mucosas jugais e labiais, compatíveis com lesões causadas por HPV. Realizou-se biópsia incisional das lesões bucais, o laudo histopatológico descreveu o fragmento de mucosa bucal que estava revestida por epitélio pavimentoso estratificado paraceratinizado com acantose proeminente, projeções focais confluentes para o tecido conjuntivo, confirmando a suspeita diagnóstica clínica. Conclusão: a HEF é uma patologia rara, benigna da mucosa, indolor e que pode se resolver espontaneamente. Portanto, é necessário o diagnóstico adequado através da biopsia e laudo histopatológico.
Introduction: focal epithelial hyperplasia (FEH) or Heck's disease is characterized as a rare benign lesion of the oral mucosa. It is usually associated with proliferation of the squamous epithelium, mainly attributed to human papillomavirus (HPV) subtypes 13 and 32. Objective: to report the case of a patient with a diagnostic suspicion of HEF, to describe its oral clinical and histopathological manifestations. Methodology: hale, 38 years old, black, attended the University Service with a complaint of burning in the oral mucosa. On clinical examination, she presented multiple papular lesions, firm to palpation, pink in color, with agglomerated or isolated papules, located in the alveolar ridge, inserted gingiva free from the upper and lower arch, jugal and labial mucosa, compatible with lesions caused by HPV. An incisional biopsy of the oral lesions was performed, the histopathological report described the fragment of oral mucosa that was lined with parakeratinized stratified squamous epithelium with prominent acanthosis, focal projections confluent to the connective tissue, confirming the clinical diagnostic suspicion. Conclusion: FEH is a rare, benign mucosal pathology, painless and can resolve spontaneously. Therefore, proper diagnosis through biopsy and histopathological report is necessary.

Some genotypes of the human papilloma virus (HPV) in the oral cavity cause genetic instability that may lead to cancer. Clinical and histological diagnoses are key tools; however, molecular techniques allow predicting, detecting and monitoring the disease. Objective: To identify the frequency of four high-risk HPV genotypes and their association with lesions in the oral cavity. Materials and Methods: Descriptive cross-sectional study with a sample of 48 patients diagnosed with hyperplastic lesions and others currently classified as potentially malignant disorders (PMDs) of the oral cavity, who underwent biopsies, histopathological analysis, and HPV16, 18, 31, and 45 detection and genotyping by polymerase chain reaction (PCR). Results: Epithelial hyperplasia was the most frequent lesion found in 45.8% (n=22) of patients. Nicotine palatinus and leukoplakia were found in 8.3% and 6.2%, respectively; oral cancer in 6.2%. The total frequency of HPV was 12.5% (6/48). Oral papilloma was found in 6.1% (3/48), and nicotine palatinus and oral cancer in 2.0% each (1/48). HPV16, HPV31, and HPV45 were detected, while HPV18 was not observed. HPV16 was the most frequent genotype found (4 out of 6 patients), while HPV31 and HPV45 were found in one patient each. Only one genotype per lesion was found. The presence of HPV was associated with lesions (χ2=11.810; p=0.0375). No significant association with age and gender was found. Conclusion: High-risk HPV continues to be present in oral lesions. The HPV16 viral genotype was the most frequent in the studied lesions.

Objective: Multifocal epithelial hyperplasia (MEH) or Heck's disease is a rare benign disorder caused by Human Papilloma Virus (HPV). It is characterized by multiple soft well demarcated nodules of the oral mucosa. They are commonly seen in buccal, labial and lingual mucosa. However, tonsilar and gingival lesions have also been reported. A detailed clinical history, examination and histopahological review is needed to arrive at a diagnosis. The aim of this report is to show the successful treatment of MEH using Salicylic acid and Zinc supplement. Case Report. Two cases of a 5year old Hausa girl and 7-year-old Hausa boy with a widespread oral lesion of 8 months and 1-year duration respectively. The diagnosis of the case reported were based on clinical evaluation and histopathological investigation. The presence of multiple painless pink nodules and papules on the lips, buccal mucosa and the gingiva as well as histological presence of koliocytes and mitosoid seen on hematoxylin and eosin slide led to the diagnosis of MultifocalEpithelial Hyperplasia. Conclusion: We reported 2 cases of MEH, a rare benign oral mucosa lesion in a 5-year-old Hausa female and a 7year old Hausa male in North-West Nigeria who presented with 8 months and 1-year history of widespread oral mucosa lesion respectively and was treated successfully using salicylic acid and zinc supplement

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.

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.

Focal epithelial hyperplasia (FEH) is a human papillomavirus (HPV)-induced alteration of the oral mucosa that presents with a clinically distinct appearance. While other HPV-infected lesions such as squamous papilloma, verruca vulgaris, and condyloma acuminatum involve the skin, oral mucosa, and genital mucosa, FEH occurs only in the oral mucosa. The affected oral mucosa exhibits multiple papules and nodules with each papule/nodule being flat-topped or sessile. The affected region resembles the normal color of oral mucosa rather than appearing as a white color since the epithelial surface is not hyperkeratinized. Almost all cases present with multiple sites of occurrence. This rare, benign epithelial proliferation is related to low-risk HPV, especially HPV-13 and -32, and is not transformed into carcinoma. We report a case of FEH that arose on the attached gingiva of an East Asian male adult related to prosthesis without detection of any HPV subtype in HPV DNA chip and sequencing.

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.

Diversos virus pueden infectar la piel y las mucosas de los seres humanos, manifestándose en diferentes patologías, de acuerdo a la edad, género y estado inmunológico. Un grupo importante de éstos tiene capacidad de replicar en células epiteliales, originando cuadros clínicos en los cuales se evidencia la destrucción celular o bien la hiperplasia del tejido infectado. Gran parte de estos virus persisten en células infectadas por años y tienen la capacidad de reactivarse y de manifestar nuevamente enfermedades cutáneas o mucosas. En algunos casos, ésta sólo se expresa de manera subclínica en una excreción del virus por secreciones que son fuente de infección. En los últimos años, los avances en técnicas moleculares han permitido contar con metodologías diagnósticas cada vez más sensibles, específicas y rápidas. Así como también el progreso en el área de vacunas y antivirales nos entrega mayores herramientas profilácticas y terapéuticas.
Various viruses can infect the skin and the mucous membranes of human beings, manifesting itself in different diseases, according to age, gender and immune status. An important group has the ability to replicate in epithelial cells, causing clinical manifestations which evidenced the cell destruction either infected tissue hyperplasia. Much of these viruses persist in cells infected by years and have the ability to reactivate and again express cutaneous or mucosal diseases. In some cases, it is only asymptomatically shred in secretions that are a source of infection. In recent years, advances in molecular techniques have allowed to have increasingly sensitive, specific and rapid diagnostic methodologies. As well as, the progress in the area of vaccines and antivirals also gives us greater prophylactic and therapeutic tools.

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.
