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.

Fibroma traumático en mucosa labial superior: Reporte de caso / Fibróide Traumática na Mucosa do Lábio Superior: Relato de Caso / Traumatic Fibroid in Upper Lip Mucosa: Case Report

Resumen El Fibroma traumático es una alteración caracterizada por una producción exagerada de tejido conjuntivo fibroso, producida por traumas crónicos. Generalmente se encuentra en mucosa oral como carrillos o lengua. En este caso en particular debido a que la paciente tiene dentición en el maxilar inferior y edentulismo total superior, se puede apreciar como progresó la lesión en la mucosa labial. La paciente de ochenta años acudió por renovación de su prótesis total superior debido a que dejo de usarla porque estaba desadaptada. Al examen clínico se observa un agrandamiento a nivel de mucosa labial superior izquierda, no dolorosa a la palpación y de coloración ligeramente blanquecina. Se decide tomar una biopsia excisional para establecer el diagnóstico definitivo debido a que existen varias lesiones con presentación clínica similar, la lesión fue compatible con un fibroma traumático, este trabajo se presenta con el objetivo de presentar las características clínicas e histopatológicas de un fibroma traumático, enfatizando la importancia de un diagnóstico temprano y oportuno para efectuar un tratamiento eficaz. Es importante considerar que, si la intervención quirúrgica no se acompaña con la rehabilitación protésica oral, pudiera aparecer una recidiva de la lesión.

Resumo Fibroma Traumático é uma alteração caracterizada por uma produção exagerada de tecido conjuntivo fibroso, produzido por traumas crónicos. É geralmente encontrada na mucosa oral, como bochechas ou língua. Neste caso particular, devido ao fato do paciente ter dentição no maxilar inferior e edentulismo total no maxilar superior, pode-se ver como a lesão na mucosa labial progrediu. A paciente de 80 anos veio para a renovação da sua prótese total superior porque deixou de a usar por ser inapta. Ao exame, foi observado um aumento da mucosa do lábio superior esquerdo, que não era doloroso à palpação e tinha uma cor ligeiramente esbranquiçada. Foi decidido fazer uma biópsia excisional para estabelecer o diagnóstico definitivo, pois existem várias lesões com apresentação clínica semelhante, a lesão era compatível com um fibróide traumático, este trabalho é apresentado com o objetivo de apresentar as características clínicas e histopatológicas de um fibróide traumático, enfatizando a importância do diagnóstico precoce e oportuno para o tratamento eficaz. É importante considerar que se a intervenção cirúrgica não for acompanhada por uma reabilitação protética oral, teria surgido uma recidiva da lesão.

Abstract Traumatic Fibroma is a disorder characterized by an exaggerated production of fibrous connective tissue, produced by chronic trauma. It is usually found in oral mucosa such as cheeks or tongue. In this particular case, due to the fact that the patient has dentition in the lower jaw and total edentulism in the upper jaw, it can be seen how the lesion in the lip mucosa progressed. The eighty year old patient came for renewal of her upper total prosthesis because she stopped using it because she was unfit. On examination, an enlargement was observed at the level of the upper left lip mucosa, which was not painful on palpation and was slightly whitish in colour. It was decided to take an excisional biopsy to establish the definitive diagnosis because there are several lesions with similar clinical presentation, the lesion was compatible with a traumatic fibroid, this work is presented with the aim of presenting the clinical and histopathological characteristics of a traumatic fibroid, emphasizing the importance of early and timely diagnosis for effective treatment. It is important to consider that if the surgical intervention is not accompanied by oral prosthetic rehabilitation, a recurrence of the injury would have appeared.

Locations of greater involvement in the mouth were upper and lower labial mucosa (representing 100%). Anatomical-pathological study revealed in all cases presence of epithelial acanthosis, papillomatosis and koilocytiosis. The greatest number of acid applications was three and four episodes with 27%, average time for lesion disappearance was 61.3 days. No relapse was observed in 100% of cases. Conclusion: Trichloroacetic acid application in focal epithelial hyperplasia cases is an effective technique which achieves rapid, atraumatic stress-free lesion resolution which did not generate fear in involved patients.

Hiperplasia epitelial focal o enfermedad de Heck. Presentación de un caso / Epithelial Focal Hyperplasia or Heck Disease. Case presentation

La hiperplasia epitelial focal o enfermedad de Heck es una enfermedad poco frecuente de la mucosa bucal. Afecta principalmente a niños, sin distinguir sexo o grupo étnico. Clínicamente se caracteriza por la presencia de pápulas blancas o de igual coloración que la mucosa oral, de pequeño tamaño, asintomáticas y con tendencia a confluir y formar lesiones papilomatosas. Esta enfermedad se ha asociado con infección por virus del papiloma humano y a factores genéticos. Se presenta el caso de una paciente de ocho años, que acudió a consulta de Dermatología en el Hospital Andino de Chimborazo, por lesiones en mucosa bucal con correspondencia clínica e histopatológica con la enfermedad de Heck.

Epithelial Focal Hyperplasia or Heck disease is an infrequent disease of the oral mucosa. It mainly affects children, without distinguishing sex or ethnic group. It is clinically characterized by the presence of white papules or of similar colour of the oral mucosa, small size, asymptomatic and with the tendency to converge and form papillomatous lesions. This disease has been associated with infection by human papilloma virus and genetic factors. A case of an eight year old girl is presented, who came to the Dermatology consultation at Andino Hospital Chimborazo Ecuador, with lesions in the oral mucosa with clinical and histopathological correspondence with Heck disease.

Papilloma of lip associated with human papilloma viruses‑32 infection in a child.

Squamous papilloma is the most common benign oral epithelial lesion, and it is well known to be associated with human papilloma virus 6 and 11. Here, we report a case of squamous papilloma associated with human papilloma viruses (HPV)‑32 in a 4‑year‑old boy who presented with a verrucous lesion on the lower lip. HPV‑32 is often associated with a rare benign condition focal epithelial hyperplasia (FEH). A limited number of lesions and the absence of characteristic histology ruled out FEH in our patient. To the best of our knowledge, the association of oral squamous papilloma with HPV‑32 is hitherto unreported.

Hiperplasia epitelial focal. Presentación de un caso / Focal Epithelial Hyperplasia. A Case Report

La hiperplasia epitelial focal, conocida también como enfermedad de Heck, es relativamente rara; ocurre en niños y adolescentes. Se presenta el caso de una paciente de 20 años que fue atendida en al Hospital Universitario Manuel Ascunce Domenech, de Camagüey, por presentar lesiones papulares de diez meses de evolución. Se descartaron otras enfermedades virales, pero se concluyó por estudios histológicos que se trataba de la enfermdedad de Heck, la cual es conocida entre los odontólogos, pero poco por pediatras, internistas y dermatólogos. Por su etiología, muchos casos tienen relación con la infección por el virus del papiloma humano. El tratamiento, cuando la enfermedad progresa, puede realizarse con excisión, tratarse con láser o crioterapia. En esta paciente se empleó el último procedimiento, con buenos resultados pues se encuentra totalmente asintomática.

Focal epithelial hyperplasia, also known as Heck’s disease, is relatively rare, occurring mostly in children and adolescents. A case of a 20 year-old female patient treated at the Manuel Ascunce Domenech University Hospital in Camagüey due to papular lesions, which had evolved for ten months, is presented. Other viral diseases were ruled out; however based on histological studies, it was concluded that she suffered from Heck disease, which is frequently treated by dentists, but little known among pediatricians, internists and dermatologists. Because of its etiology, many cases are related to human papilloma virus infection. When the disease evolves, treatment can involve excision, laser surgery or cryotherapy. The latter method was used in this patient with satisfactory results, as she is completely asymptomatic.

Focal epithelial hyperplasia arising after delivery of metal-ceramic fixed dental prosthesis

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.

Focal epithelial hyperplasia in a Brazilian family / Hiperplasia epitelial focal em uma família brasileira

Focal Epithelial Hyperplasia (FEH) or Heck’s disease is a rare and benign condition characterized by cell proliferation in the squamous epithelium, which is manifested clinically as verrucous projections. It is associated with Human Papillomavirus (HPV) subtype 13 or 32, and it is often observed in children, young adults, and middle aged individuals, as well as some ethnic groups such as Indians and Eskimos, which suggests a possible hereditary influence. Objective: knowing that FEH is a rare disease among the Brazilian population, this article reports a case of FEH in a Brazilian family. Case report: a 27 year-old woman was assisted in the Department of Dentistry of the Federal University of Rio Grande do Norte (UFRN) showing round, plane, and well-defined lesions localized in the oral cavity, with an evolution of six years. Lesions underwent incisional biopsy, and the microscopic analysis revealed epithelial changes such as epithelium hyperplasia and prominent acanthosis. These histopathologic findings were consistent with the clinical hypothesis of FEH. Final considerations: this report reinforces the need for an accurate clinical assessment, so dentists are able to recognize, diagnose, and treat FEH in their own patients.

A hiperplasia epitelial focal (HEF) ou doença de Heck é uma doença benigna, rara e caracterizada por proliferação celular no epitélio escamoso, que se manifesta clinicamente como projeções verrucosas. É associada com o papilomavírus (HPV), subtipo humano 13 ou 32, e, muitas vezes, é observada em crianças, adultos jovens e pessoas de meia-idade, bem como em alguns grupos étnicos, como os índios e esquimós, o que sugere uma possível influência hereditária. Objetivo: sabendo que a HEF é uma doença rara na população brasileira, este artigo relata um caso de HEF em uma família brasileira. Relato de caso: paciente feminina, de 27 anos de idade, foi atendida no Departamento de Odontologia da Universidade Federal do Rio Grande do Norte (UFRN), mostrando lesões bem definidas, arredondadas, planas, localizadas em cavidade oral e com uma evolução de seis anos. As lesões foram submetidas a biópsia incisional, e a análise microscópica revelou alterações epiteliais, como hiperplasia do epitélio e acantose proeminente. Esses resultados histopatológicos foram consistentes com a hipótese clínica de HEF. Considerações finais: este relatório reforça a necessidade de uma avaliação precisa da clínica, para dentistas serem capazes de reconhecer, diagnosticar e tratar HEF em seus próprios pacientes.
