ABSTRACT
Os papilomavírus humanos (HPVs) pertencem à família Papillomaviridae e podem infectar a epiderme e os epitélios da cavidade oral, orofaringe, laringe, árvore brônquica, esôfago, bexiga, ânus e trato genital. Na boca, o HPV está relacionado com o surgimento de lesões verrucosas benignas, sendo a mais frequente o papiloma escamoso oral. Essa lesão apresenta crescimento exofítico, assintomático e normalmente solitário. Dessa forma, o presente estudo teve por objetivo relatar três casos de papiloma escamoso oral com características distintas. Nos três casos foram realizadas biópsias excisionais e os espécimes avaliados por histopatologia. Os pacientes foram acompanhados por um período mínimo de doze meses, sem histórias de recidivas. Acredita-se que o conhecimento das principais características clínicas e histopatológicas dessa lesão auxilie o dentista no processo de diagnóstico e tratamento dessa patologia.
Human papillomaviruses (HPVs) belong to the Papillomaviridae family and can infect the host's epithelial cells, generating lesions. They have more than one hundred subtypes and these can infect the epidermis and epithelium of the oral cavity, oropharynx, larynx, bronchial tree, esophagus, bladder, anus and genital tract. In the mouth, HPV is related to the appearance of benign verrucous lesions, the most frequent the oral squamous papilloma. This lesion reveal exophytic growth, asymptomatic and usually solitary. Thus, the present paper aimed to report three cases of oral squamous papilloma with different characteristics. In the three cases, excisional biopsies were performed and the specimens were evaluated by histopathology. Patients were followed for a minimum period of twelve months, with no recurrences. It is believed that the knowledge of the main clinical and histopathological characteristics of this lesion helps the dentist in the process of diagnosis and treatment of this pathology.

La papilomatosis confluente y reticulada es una dermatosis infrecuente, benigna, de curso crónico y etiopatogenia desconocida. Actualmente, se acepta que se debe a un trastorno de la queratinización. Se caracteriza por máculas y pápulas hiperpigmentadas, que coalescen en el centro y adoptan un patrón reticular en la periferia. Se la puede confundir con otras patologías, como la pitiriasis versicolor y la acantosis nigricans. Con la administración de minociclina por vía oral suelen obtenerse excelentes resultados. Se comunica el caso de un paciente con diagnóstico de papilomatosis confluente y reticulada. Se describen sus características clínicas, criterios diagnósticos y trata-miento instaurado.
Confluent and reticulated papillomatosis is an infrequent, benign dermatosis of chronic course and unknown etiopathogenesis. Currently it is accepted that this dermatosis is due to a keratinization disorder. It is characterized by hyperpigmented macules and papules that coalesce in the center and adopt a reticular pattern in the periphery. It can be confused with other pathologies such as pityriasis versicolor and acanthosis nigricans. Oral minocycline usually shows excellent results. The present work reports a case of a patient with a diagnosis of confluent and retic-ulated papillomatosis, describing its clinical characteristics, diagnostic criteria and established treatment.

La papilomatosis laríngea es la neoplasia laríngea benigna más común y está causada por el virus de papiloma humano. Se considera que la papilomatosis laríngea tiene un papel independiente como factor de riesgo de cáncer; se clasifica dentro de tres grupos de acuerdo con sus características clínicas: juvenil, adulto y recurrente. Su incidencia asociada a neoplasia maligna es del 4%. Objetivos: Determinar si existen factores de riesgo asociados al tipo de papilomatosis laríngea; y si existe relación con el tipo de papilomatosis y neoplasias asociadas. Metodología: Estudio observacional descriptivo de pacientes que acuden al servicio de Otorrinolaringología del Hospital General San juan de Dios y su caracterización. Resultados: De los 33 pacientes evaluados con papilomatosis laríngea, 51 % fueron del género masculino, la edad promedio sin incluir pacientes pediátricos fue de 23 años. La mediana de reintervenciones es de 4 veces, y la mayoría tiene pérdida del seguimiento. La papilomatosis tipo infantil es la más común con pacientes de 7 a 14 años de edad. Los pacientes con papilomatosis adulta presentaron más factores de riesgo que los pacientes con papilomatosis infantil y recurrente, p=0.01. Los pacientes presentan ronquera, disfonía y dificultad respiratoria. El diagnóstico se realiza por clínica con laringoscopía sin biopsia en la mitad de los pacientes. El 9% de los pacientes estudiados presentaron neoplasia asociada. El número de reintervenciones está asociado a un mayor riesgo de progresión a neoplasia. Conclusión: Los pacientes con papilomatosis adulta presentaron más factores de riesgo que los pacientes con papilomatosis infantil, y el 9% de los pacientes presentan una neoplasia asociada, más alta de la reportada en la literatura.(AU)
Laryngeal papillomatosis is the most common benign neoplasm and is caused by the human papilloma virus. Laryngeal papillomatosis is considered to have an independent role as risk factor. Laryngeal papillomas are classified into three groups, according to their clinical characteristics: juvenile, adult and recurrent. 4% is associated with neoplasia. Objectives: Determine if there are risk factors associated with the type of laryngeal papillomatosis and if there is a relationship with the type of papillomatosis and associated neoplasms. Methodology: Descriptive observational study of patients attending the Otolaryngology service of the General Hospital San Juan de Dios de Guatemala and their characterization. Results: Of the 33 patients evaluated with laryngeal papillomatosis, 51% were male, with an average age of 23 years. The median number of reoperations is 4, and most do not return to follow-up. Infantile type papillomatosis is the most common, with patients 7 to 14 years of age. Patients with adult papillomatosis had more risk factors than patients with infantile and recurrent papillomatosis, p= 0.01. Patients present hoarseness, dysphonia and respiratory distress upon admission. Diagnosis is made clinically with laryngoscopy without biopsy in half of the patients. 9% of the patients studied had associated neoplasia. The number of reoperations is associated with an increased risk of developing a neoplasm. Conclusion: Patients with adult papillomatosis presented more risk factors than patients with infantile papillomatosis. And 9% of the patients present associated neoplasia, higher than reported in the literature

A papilomatose laríngea é uma neoplasia benigna causada pelo papilomavírus humano (HPV), sendo os tipos 6 e 11 os mais comuns, e que ocorre em dois grupos etários, juvenil e adulto. A possível coinfecção viral tem sido sugerida em lesões de cabeça e pescoço; nesse sentido, o Epstein Barr vírus (EBV), que também apresenta tropismo por células epiteliais vem sendo estudado neste grupo de lesões. Os objetivos deste estudo foram genotipar os HPVs, investigar a presença de EBV-DNA por PCR e EBV-RNA por hibridização in situ. Além disso, associar a presença de EBV com a imunoexpressão de CD21, os resultados obtidos com a escala laringoscópica de Derkay et al. (1998) e com os dados clinicopatológicos. Oitenta casos de papilomatose laríngea, juvenil (n=36) e adulta (n=44), foram retrospectivamente analisados e subdivididos em grupos de menor e maior severidade, baseando-se na escala de Derkay. Todas as amostras foram HPV posivitas, com 49 casos HPV 6, 26 casos HPV 11, 4 casos HPV 6 e 11, e 1 caso HPV 16. A presença de EBV-DNA foi detectada em 9 amostras, entretanto EBV-RNA não foi não foi identificado em nenhuma amostra. Assim como a presença do EBV-DNA, a imunoexpressão de CD21 não se associou estatisticamente com quaisquer variáveis. A presença de HPV 6 foi mais comum em PLA e, o HPV 11 foi mais comum (p=0,02) e maior em casos de maior severidade (p=0,04), no grupo juvenil. A presença do EBV provavelmente não desempenha papel importante na progressão/severidade desta patologia(AU)
Laryngeal papillomatosis is a benign neoplasm caused by the human papillomavirus (HPV), been types 6 and 11 the most commonly related, and is divided into two groups: juvenile and adult. Viral coinfection has been suggested in head and neck lesions; in this sense, Epstein Barr virus (EBV), which also presents tropism for epithelial cells, has been studied in this group of lesions. The aims of this study are to perform HPV genotyping, investigate EBVDNA presence by PCR and EBV-RNA by in situ hybridization; and associate EBV presence with CD21 immunoexpression. Finally, the results were associated with Derkay laryngoscopic score. Eighty cases of laryngeal papillomatosis, juvenile (n = 36) and adult (n = 44) were retrospectively subdivided into low-risk and high-risk of severity based on the Derkay index. All samples were HPV-positive, with 49 cases of HPV 6, 26 cases of HPV 11, 4 cases of HPV 6 and 11, and 1 case of HPV 16. The presence of EBV-DNA was detected in 9 samples, however EBV-RNA was not identified in any sample. As the presence of EBV-DNA, the CD21 immunoexpression was not statistically associated with any variables. The presence of HPV 6 was more common in ALP, HPV 11 was more common (p = 0.02) and higher in cases of higher severity (p = 0.04) in juvenile group. The presence of EBV probably does not play an important role in the progression/severity of this pathology(AU)

ABSTRACT Oral squamous papilloma is a benign tumor whose pathogenesis has been associated with human papillomavirus infection. Thus, it is noteworthy that human papillomavirus infection is one of the risk factors associated with the development of cervical, anogenital, pharynx, larynx and oral cavity carcinomas. Oral squamous papilloma can affect any region of the oral cavity, and transmission of human papillomavirus can occur by direct contact, sexual intercourse or from mother to child during delivery. The diagnosis is clinical and histopathological, with surgical removal representing the treatment of choice. Recently, widefield optical fluorescence has been used as a complementary examination to the conventional clinical examination in the screening of oral pathological lesions and for the delimitation of surgical margins. We report a case of oral squamous papilloma with its clinical, histopathological features and, in addition, from the perspective of wide field optical fluorescence.
RESUMO O papiloma escamoso oral é um tumor benigno, cuja patogênese tem sido associada à infecção pelo papilomavírus humano. A infecção pelo papilomavírus humano é um dos fatores de risco associado ao desenvolvimento dos carcinomas cervicais, anogenitais, faríngeos, laríngeos e da cavidade oral. O papiloma escamoso oral pode acometer qualquer região da cavidade oral, e a transmissão do papilomavírus humano ocorre por contato direto, relação sexual ou de mãe para filho durante o parto. O diagnóstico é clínico e histopatológico, e a remoção cirúrgica representa o tratamento de escolha. Recentemente, a fluorescência óptica de campo amplo tem sido empregada como exame complementar ao exame clínico convencional, no rastreio de lesões patológicas orais e para delimitação de margens cirúrgicas. Relatamos um caso de papiloma escamoso oral com suas características clínicas e histopatológicas, sob a perspectiva da fluorescência óptica de campo amplo.

La papilomatosis laríngea juvenil es una enfermedad infrecuente causada por el virus del papiloma humano, principalmente, los tipos 6 y 11. Es el tumor laríngeo benigno más común en los niños. Debe pensarse, en esta patología, en todo niño con disfonía persistente y progresiva, acompañada o no de estridor y dificultad respiratoria. La laringoscopía flexible con anestesia local permite visualizar las típicas lesiones de características verrugosas. El diagnóstico se confirma mediante la anatomía patológica. El tratamiento existente es paliativo y consiste, principalmente, en la escisión quirúrgica de los papilomas para mantener la vía aérea sin obstrucción y mejorar la calidad de la voz, pero tiene una alta tasa de recidiva. Se presentan 20 pacientes con papilomatosis laríngea juvenil. Se describen las manifestaciones clínicas, el diagnóstico y el tratamiento de esta patología.
Juvenile laryngeal papillomatosis is an uncommon disease caused by human papilloma virus, mainly types 6 and 11. It is the most common benign laryngeal tumor in children. This condition should be suspected in any children with persistent and progressive dysphonia with or without stridor and respiratory distress. Flexible laryngoscopy under local anesthesia allows to visualize the typical wart-like lesions. The diagnosis is confirmed by pathological anatomy. Existing treatment is palliative and consists mainly of the surgical excision of the papillomas to maintain the airway without obstruction and to improve the quality of the voice, but it has a high rate of relapse. We present 20 patients with juvenile laryngeal papillomatosis. We describe the clinical manifestations, the diagnostic methods and the treatment of this pathology.

Biliary papillomatosis is rare, and its pathogenic mechanisms are not yet clear. Because of its high risk for malignancy transformation, surgical resection is regarded as a standard treatment. Photodynamic therapy (PDT) has been used by the intravenous administration of hematoporphyrin derivative followed by laser exposure. A photochemical process causes disturbance of the microvascular structure and degradation of membrane. Cholangitis is a major complication after PDT. A healthy 56-year-old man was diagnosed with biliary papillomatosis involving the common hepatic duct, both proximal intrahepatic bile ducts (IHD), and the right posterior IHD. After biliary decompression by endoscopic nasobiliary drainage, PDT was performed to avoid extensive liver resection and recurrence using endoscopic retrograde cholangiographic guidance. After portal vein embolization, the patient underwent extended right hemihepatectomy. Following administration of chemoradiation therapy with tegafur-uracil and 45 Gy due to local recurrence at postoperative 13 months, there was no local recurrence or distant metastases. This is the first case report on PDT for biliary papillomatosis in Korea. Preoperative PDT is beneficial for reducing the lesion in diffuse or multifocal biliary papillomatosis and may lead to curative and volume reserving surgery. Thus, PDT could improve the quality of life and prolong life expectation for biliary papillomatosis patients.

A retrospective study of 24 cases of papillomas in dogs was performed from January 2001 to March 2011. Additionally, immunohistochemistry (IHC) was used to characterize and evaluate the samples. We found that disease was observed more in mixed breed dogs, ages ranging from 6 months to 10 years (mean 3.1 years), and there was no gender predilection. The main lesion sites were the skin (75%), lips (16.7%), and eyelids (8.3%). Upon histological evaluation, we observed papillary exophytic proliferation of squamous epithelium and papillary endophytic proliferation (inverted) in 87.5% and 12.5% of cases, respectively. The tumors were characterized by spinous layer hyperplasia (87.5%) with koilocytes (70.8%) and intranuclear pale basophilic inclusions bodies (8.3%), prominent granular layer with large amounts of keratohyalin granules (95.8%), and hyperkeratosis in the stratum corneum (100%). Positive immunostaining for Papillomavirus was found in 83.3% of cases, which were distributed between the granular layer and the stratum corneum. These findings indicate the following: that papillomas in dogs are caused by Papillomavirus, the viral cytopathic effect induces epithelial lesions, viral particles are found inside the cell nuclei, and inclusions bodies are rare.
Foi realizado um estudo retrospectivo de 24 casos de papilomas em cães diagnosticados no período de janeiro 2001 a março de 2011, bem como a sua caracterização imuno-histoquímica (IHQ). Cães sem raça definida foram os mais afetados, a idade média foi de 3,1 anos, com variação de 6 meses a 10 anos e não houve predileção sexual. Quanto à localização das lesões, 75,0% estavam na pele, 16,7% no lábio e 8,3% em pálpebra. Na avaliação histológica havia proliferação papilar exofítica do epitélio escamoso em 87,5% e papilar endofítica (invertido) em 12,5%. O tumor era caracterizado por hiperplasia do estrato espinhoso (87,5%) com coilócitos (70,8%) e inclusões intranucleares basofílicas pálidas (8,3%); o estrato granular estava proeminente com grande quantidade de grânulos de querato-hialina (95,8%); e havia hiperqueratose do estrato córneo (100%). Na avaliação IHQ para Papillomavirus houve marcação nos estratos granuloso e córneo em 83,3%. Estes achados indicam que os papilomas em cães são causados por Papillomavirus, as lesões epiteliais são decorrentes do efeito citopático viral, as partículas virais estão no núcleo das células e corpúsculos de inclusão são raros.
