Prevalencia de lesiones en mucosa bucal y su relación con condición sistémica, edad y sexo / Prevalence of lesions in the oral mucosa and its relationship with systemic condition, age and gender

Este estudio tiene la finalidad de analizar la prevalencia de variantes de la normalidad y patología en la mucosa de la cavidad bucal por zona anatómica, de una población controlada en una clínica estomatológica universitaria de pregrado en el Estado de México. Se trata de un estudio transversal, descriptivo y observacional de 542 pacientes, de los cuales el 62.7% (340) pertenecen al sexo femenino y 37.3% (202) al masculino; la edad se distribuyó en un rango de dos a 85 años con una media de 28 años y fue categorizada en cinco grupos etarios: 2 a 12, 13 a 18, 19 a 35, 36 a 69 y > 70 años. En este estudio participaron una especialista en patología bucal, un especialista en odontopediatría y una pasante de la licenciatura de estomatología quien fungió como ayudante de investigación. Fueron identificadas 13 variantes de la normalidad y 52 lesiones en total, mismas que son reportadas por zona anatómica, por rangos de edad y por sexo. El número de condiciones y lesiones diagnosticadas por paciente varió de una a cinco en 87.27% y en el restante 12.73% no se detectó ninguna. Las variantes de la normalidad o condiciones más frecuentes fueron lengua fisurada con 12.17%, apéndice mucoso en frenillo vestibular con 11.25% y gránulos de Fordyce con 10.88%. Las lesiones más prevalentes por zona anatómica fueron: nevo intradérmico con 2.39% en labio externo superior e inferior; queilitis simple con 11.43% en la interfase de piel y mucosa de los labios (borde bermellón); úlcera traumática con 3.87% en mucosa labial; absceso de origen dental con 1.42 en encía; frenillo con inserción baja 1.84% en frenillos; úlcera traumática con 5.53% en mucosa bucal; candidiasis atrófica crónica con 5.53% en paladar; amígdalas hipertróficas con 8.11% en zona amigdalina; lengua pilosa con 1.66% en lengua; úlcera traumática con 3.69% en piso de boca; granuloma piógeno con 0.18% en proceso alveolar; y por último, hipertrofia de glándulas salivales labiales con 0.55% asociadas a presencia de aparatología ortodóntica. Finalmente se llevó a cabo una prueba de χ2 de Pearson para establecer correlación entre variables dependientes e independientes, encontrando significancia estadística de p < 0.000 entre lesiones de lengua y condición sistémica y edad en relación a lesiones de lengua, paladar y labios con p < 0.000 (AU)

The purpose of this study is to analyze the prevalence of variants of normality and pathology in the mucosa of the oral cavity by anatomical area in a controlled population in a university undergraduate stomatological clinic in the state of Mexico. This is a cross-sectional, descriptive and observational study of 542 patients, of which 62.7% (340) belonged to the female gender and 37.3% (202) to the male gender, the age was distributed in a range of two to 85 years with a mean of 28 years and was categorized in five age groups: 2 to 12, 13 to 18, 19 to 35, 36 to 69 and > 70 years. A specialist in oral pathology, a specialist in pediatric dentistry and an intern in stomatology who served as a research assistant participated in this study. Thirteen variants of normality and 52 lesions in total were identified and reported by anatomical area, age range and gender. The number of conditions and lesions diagnosed per patient ranged from one to five in 87.27% and none were detected in 12.73% of the population studied. The most frequent variants of normality or conditions were fissured tongue with 12.17%, mucous appendage in the vestibular frenulum with 11.25% and Fordyce granules with 10.88%. The most prevalent lesions by anatomical area were: intradermal nevus with 2.39% in upper and lower external lip; simple cheilitis with 11.43% in the interphase interface of skin and mucosa of the lips (vermilion border); traumatic ulcer with 3.87% in labial mucosa; abscess of dental origin with 1.42 in gingiva; frenulum with low insertion 1.84% in frenulum; traumatic ulcer with 5. 53% in buccal mucosa; chronic atrophic candidiasis with 5.53% in palate; hypertrophic tonsils with 8.11% in tonsillar area; hairy tongue with 1.66% in tongue; traumatic ulcer with 3.69% in floor of mouth; pyogenic granuloma with 0.18% in alveolar process and finally; hypertrophy of labial salivary glands with 0.55% associated with the presence of orthodontic appliances. Finally, a Pearson's χ2 test was carried out to establish correlation between dependent and independent variables, finding statistical significance of p < 0.000 between tongue lesions and systemic condition and age in relation to tongue, palate and lip lesions with a p < 0.000 (AU)

Granuloma piógeno en el dorso lingual: caso clínico / Pyogenic granuloma in the lingual dorsum: a clinical case

El granuloma piógeno es una lesión benigna en la cavidad bucal, no neoplásica. Es una entidad fre- cuentemente asociada a la expansión de los tejidos blandos de la cavidad bucal. Se presenta, con mayor frecuencia, en individuos del género femenino, con edades comprendidas entre la segunda y cuarta década de vida. El tratamiento es mediante escisión quirúrgica con un pequeño margen de seguridad, y los agentes irritantes deben extraerse concomitan- temente para la curación de la lesión. Este trabajo tuvo como objetivo informar un caso de granuloma piógeno en el dorso de la lengua en una paciente del género femenino de 69 años. Los autores destacaron la importancia del conocimiento de la patología bucal por parte del Cirujano Dentista para poder realizar un correcto diagnóstico diferencial de otras lesiones, con el fin de realizar el tratamiento adecuado (AU)

Pyogenic granuloma is a quite common non-neoplasic benign lesion in the oral cavity. It is one of the entities most frequently associated with the soft tissues' expansion of the oral cavity, specifically in females, in the age group between the second and the fourth decade of life. The treatment is by surgical excision with a small margin of safety. For the healing of the lesion irritants should be concomitantly removed. This study aimed to report a case of pyogenic granuloma on the lingual dorsum of a 69-year-old female patient. The authors concluded highlighting the importance of the knowledge of oral pathology by the Dental Surgeon, to perform a correct differential diagnosis of other lesions to perform the appropriate treatment (AU)

Frecuencia de Patologías y Condiciones de Lengua Observadas en Población Pediátrica / Frequency of Pathologies and Conditions of Tongue Observed in Pediatric Population

Las patologías y condiciones linguales constituyen una proporción considerable del total de lesiones de la mucosa oral. Los estudios epidemiológicos que describen su frecuencia en la población pediátrica son escasos y variables. El objetivo de este estudio fue establecer la frecuencia de patologías y condiciones de lengua en niños atendidos en la Facultad de Odontología de la Universidad de Chile. Se realizó un estudio observacional, descriptivo y de corte transversal donde se examinaron pacientes pediátricos de 4 a 13 años de ambos sexos. De un total de 179 pacientes, un 53 % presentó al menos una patología o condición lingual. El rango etario de 11 a 13 años presentó un mayor OR de presentar lesiones y/o condiciones linguales al ser comparado con los otros rangos etarios (valor p<0,05). La patología o condición lingual más frecuente fue la lengua saburral (39 %), seguida por la lengua fisurada (15 %), la hipertrofia de papilas linguales (5 %) y la lengua geográfica (3 %). La ubicación más frecuente fue la base lingual con un 59 % del total de ubicaciones registradas. En base a la escasa evidencia que existe y a la alta frecuencia encontrada en esta investigación, se debe destacar la importancia del conocimiento de las patologías y condiciones linguales en niños. A través de este estudio, se sientan bases para futuras investigaciones que ayuden a odontólogos a reconocer, diagnosticar y tratar estas condiciones cuando sea necesario.

Lingual pathologies and conditions constitute a considerable proportion of the total lesions of the oral mucosa.The epidemiological studies that describe its frequency in the pediatric population are limited and variable. The objective of this study was to establish the frequency of pathologies and lingual conditions in children attended at the Faculty of Dentistry of the University of Chile. An observational, descriptive and cross-sectional study was carried out where pediatric patients between 4 and 13 years of both sexes were examined. Of a total of 179 patients, 53 % had at least one pathology or lingual condition. The age range of 11 to 13 years presented a higher OR of presenting lesions and/or lingual conditions when compared with the other age ranges (p value <0.05). The most frequent pathology or lingual condition was coated tongue (39 %), fast due to the fissured tongue (15 %), the hypertrophy of the lingual papillae (5 %) and the geographic tongue (3 %). The most frequent location was the lingual base with 59 % of the total frequency registered. Based on the little evidence that exists and the high frequency found in this research, the importance of knowledge of pathologies and lingual conditions in children should be highlighted. Through this study, foundations are laid for future investigations that help dentists recognize, diagnose, and treat these conditions when necessary.

Ulceración por trauma crónico: una lesión simuladora. Informe de un caso clínico / Oral traumatic ulceration: a mimic lesion. Report of a case

Objetivo: Describir la importancia del reconocimiento oportuno del trauma crónico de la mucosa bucal producido por un elemento dentario que generó una lesión erróneamente diagnosticada como neoplasia maligna. Caso clínico: Una paciente de sexo femenino, de 79 años de edad, realizó una consulta estomatológica por una lesión lingual con un diagnóstico presuntivo de cáncer. Tras la inspección de la cavidad bucal y el estudio anatomopatológico se diagnosticó úlcera asociada a trauma dentario. La intervención terapéutica odontológica (eliminación del trauma) resolvió el cuadro cínico. Conclusión: El trauma crónico en la mucosa bucal puede generar lesiones sobre mucosa sana o bien complicar una patología preexistente. En el presente caso, la inspección de la cavidad bucal con la identificación y la eliminación del trauma lograron la reparación de la lesión. El estudio anatomopatológico precisó el diagnóstico de ulceración asociada a trauma dentario (AU)

Aim: The aim of this case report is to show the importance of the early diagnosis of a traumatic lesion of the oral mucosa arising from a posterior broken tooth that was initially misdiagnosed as oral cancer. Case report: A 79-year-old female attends an appointment with the oral medicine specialist for a lesion on the lateral side of the tongue with a presumptive diagnosis of oral cancer. The examination of the oral cavity and the anatomopathological diagnosis confirmed the presence of an ulcer associated with dental trauma. The lesion healed completely with the elimination of the trauma. Conclusion: Chronic trauma in the oral cavity can produce lesions in the oral mucosa or exacerbate preexisting lesions. In this case report a thorough oral examination showed a broken tooth as the cause of trauma and after its removal the lesion healed completely. The result of the biopsy confirmed the diagnosis of an oral ulcer associated with dental trauma (AU)

RESUMEN: Las papilas fungiformes pigmentadas de la lengua, cuyas siglas son PFPT, del inglés Pigmented fungiform papillae of the tongue, es una condición asintomática, no progresiva que se presenta en personas de piel oscura, en las cuales las papilas fungiformes cambian de su color rosado natural, a una gama de café a negro. El objetivo de nuestro estudio es reportar y describir las caractetísticas clínicas, dermatoscópicas e histológicas de la PFPT por primera vez en una serie de pacientes ecuatorianos. Estudio prospectivo simple en el Centro de Especialidades Dermatológicas Garzón, período de dos años. El criterio de inclusión fue cambio de coloración a nivel lingual, se recolectaron datos demográficos, clínicos; fotografías, dermatoscopía, y biopsia, para tinción con hematoxilina-eosina y Fontana-Mason. Examinamos 8.640 pacientres, 15 (12 mujeres, 3 varones) fueron diagnosticados de PFPT. La edad promedio fue 31 años, todos fueron mestizos, con fototipo de piel predominante III y IV. El tiempo de evolución promedio en años fue 5,8. Ninguno tuvo antescedentes familiares o personales relacionados a la patología. La evaluación clínica demostró que el patrón de distribución de acuerdo a la clasificación de Holzwanger en la gran mayoría fue tipo II (13/15). En todos los casos la dermatoscopía y la histología fueron específicas demostrando hallazgos típicos y comprobatorios de PFPT.

ABSTRACT: The pigmented fungiform papillae of the tongue, whose acronyms are PFPT, of the English Pigmented fungiform papillae of the tongue, is an asymptomatic, nonprogressive condition that occurs in dark-skinned people, in which the fungiform papillae change their color natural pink, to a range of brown to black. The aim of our study is to report and describe the clinical, dermatoscopic and histological characteristics of the PFPT for the first time in a series of Ecuadorian patients. A simple prospective study at the Garzón Dermatological Specialty Center, a two-year period. The inclusion criteria was lingual change of color, demographic, clinical data were collected; photographs, dermatoscopy, and biopsy, for staining with hematoxylin-eosin and FontanaMason. We examined 8,640 patients, 15 (12 women, 3 men) were diagnosed with PFTP. The range of age was 31 years, all were mestizos, with skin phototype predominant III and IV. The range of evolution time in years was 5.8. None had family or personal precedents related to the pathology. The clinical evaluation showed that the pattern of distribution according to the Holzwanger classification in the great majority was type II (13/15). In all cases, the dermatoscopy and histology were specific, demonstrating typical and evidential findings of PFPT.

Necrosis lingual como forma de presentación de arteritis temporal / Lingual necrosis as a form of presentation of temporary arteritis

La arteritis de células gigantes es una vasculitis sistémica que compromete arterias de mediano y gran calibre, principalmente la arteria aorta y sus ramas. Su prevalencia es mayor en mujeres a partir de los 50 años, típicamente se manifiesta con fiebre, claudicación mandibular, cefalea, hiperestesia del cuero cabelludo y pérdida de la visión con neuropatía óptica isquémica anterior, en una minoría de casos aparecen síntomas menos frecuentes que dificultan y retrasan el diagnóstico. Se presenta el caso de una mujer de 76 años que consultó por dolor en la cavidad bucal con edema lingual y en cuello de 48 horas de evolución asociado a cefalea el mes previo. En el examen físico presentaba signos clínicos de isquemia lingual, por lo que se consideró como diagnóstico presuntivo compromiso isquémico por arteritis de células gigantes, e inició tratamiento con corticoides sistémicos realizándose una biopsia de arteria temporal que evidenció infiltrado linfocitario panparietal con engrosamiento de la túnica íntima y hallazgos compatibles con panarteritis. La arteritis de células gigantes debe ser sospechada en pacientes con manifestaciones de isquemia lingual, iniciándose en forma precoz el tratamiento para evitar complicaciones irreversibles.

Giant cell arteritis is a systemic vasculitis that affects arteries of medium and large caliber, mainly the aorta artery and its main branches. It is more frequent in women older than 50 years. The most common symptoms are fever, jaw claudication, headache, hyperesthesia of the scalp and loss of vision with anterior ischemic optic nerve disease. But, in a minority of cases, less frequent symptoms are observed that delay and make more difficult the diagnosis. Here, we present the case of a 76-year-old woman who came to our consultation having pain in the oral cavity and presenting tongue and neck edema for 48 hours. She had also suffered from headaches during the previous month. Because the physical examination showed clinical signs of lingual ischemia, a presumptive diagnosis of ischemic involvement due to giant cell arteritis was considered. She started a treatment with systemic corticosteroids and a temporal artery biopsy was performed. We conclude, that giant cell arteritis should be suspected in patients presenting lingual ischemia symptoms in order to start the specific treatment early enough to avoid irreversible complications.

Relationship Between Glycemic Control and Coated Tongue in Type 2 Diabetes Mellitus Patients with Xerostomia

Abstract Objective: To examine the relationship between the level of glycemic control and coated tongue in type 2 diabetes mellitus patients with xerostomia. Material and Methods: This study was an analytical survey and involved 64 type 2 diabetes mellitus patients, aged between 17 to 65 years old with 34 males and 30 females. Diagnosis of diabetes mellitus was determined from the patient's medical records. The level of glycemic control was obtained from the patient's last blood sugar examination. Xerostomia was diagnosed with a questionnaire, while coated tongue diagnosis based on clinical features and the severity of coated tongue was assessed using the Kojima index Results: There was a significant relationship between the level of glycemic control and coated tongue (p=0.0026) in type 2 diabetes mellitus patients with xerostomia. Moreover, there was a significant relationship between the level of glycemic control and the severity of the coated tongue (p=0.001). Specifically, poor glycemic control was associated with a higher occurrence of the coated tongue as well as more severe tongue coating Conclusion: There was a significant relationship between the level of glycemic control in and coated tongue in type 2 diabetes mellitus patients with xerostomia. Therefore, diabetes mellitus patients should control their level of glycemic control to prevent the oral complication of the disease.

Repercussão da anquiloglossia em neonatos: diagnóstico, classificação, consequências clÍnicas e tratamento / Repercussion of ankyloglossia in neonates: diagnosis, classification, clinical consequences and treatment

Introdução: A anquiloglossia é uma anomalia congênita que envolve alterações morfofuncionais no frênulo lingual e que pode estar atrelada às condições genéticas; apresentando-se em maior frequência no sexo masculino; e caracteriza-se por limitar os movimentos linguais. Com isso, pode contribuir na disfunção do sistema estomatognático, desencadear prejuízos na amamentação e comprometer o desenvolvimento craniofacial do neonato. Objetivo: As divergentes opiniões encontradas promovem um quadro de incerteza na escolha do protocolo de avaliação ou na intervenção, impulsionando assim a realização deste artigo. O presente artigo objetivou revisar a literatura de modo a desenvolver o conhecimento nos protocolos de avaliação para o diagnóstico da anquiloglossia, analogamente verificar as interferências condicionadas por esta anomalia no sistema estomatognático e observar as formas de tratamento para liberação do frênulo lingual. Materiais e Métodos: Foi realizada uma revisão de literatura de estudos anteriores com acesso possibilitado pelo PubMED/Medline, Lilacs, Scielo, Scopus; estabelecido o critério de artigos recém-publicados, no intervalo de 2015-2019. Conclusão: Assim, a ausência de um método de identificação que se enquadre em um padrão ouro revela a necessidade de realização de mais estudos sobre um protocolo mais eficaz para diagnóstico e classificação dessa anomalia, pois um método com maior nível de exatidão evitará intervenções inoportunas, e promoverá o conhecimento básico para realização do tratamento adequado para cada quadro de anquiloglossia.

Introduction: Ankyloglossia is a congenital anomaly involving morphofunctional changes in the lingual frenulum and which may be linked to genetic conditions; presenting more frequently in males; it is characterized by limiting lingual movements, which can contribute to the dysfunction of the stomatognathic system, triggering losses in breastfeeding and compromising the craniofacial development of the newborn. Objective: The divergent opinions found promote a picture of uncertainty in the choice of the evaluation protocol or intervention, thus driving the realization of this article. This article aimed to review the literature in order to develop knowledge in the assessment protocols for the diagnosis of ankyloglossia, similarly to verify the interferences conditioned by this anomaly in the stomatognathic system and to observe the forms of treatment for release of the lingual frenulum. Materials and Methods: A literature review of previous studies with access made possible by PubMED / Medline, Lilacs, Scielo, Scopus; the criterion for newly published articles in the 2015-2019 range was established. Conclusion: Thus, the absence of a gold-standard identification method reveals the need for further studies on a more effective protocol for diagnosing and classifying this anomaly, as a more accurate method will avoid inappropriate interventions, and will promote the basic knowledge for carrying out the appropriate treatment for each ankyloglossia picture.

Manejo Quirúrgico de Múltiples Condilomas de la Mucosa Oral en Paciente Bajo Terapia Antirretroviral de Gran Actividad / Surgical Management of Multiple Condylomas in the Oral Mucosa in Patient Undergoing Highly Active Antiretroviral Therapy

RESUMEN: El objetivo de este estudio fue reportar un caso clínico donde se realizó el manejo quirúrgico de múltiples condilomas de la mucosa oral en un paciente infectado por Virus de Inmunodeficiencia Humana (VIH) bajo Terapia Antirretroviral de Gran Actividad (TARGA). Hombre de 58 años en tratamiento por infección con VIH en TARGA hace 17 años, que acude al Servicio de Cirugía Maxilofacial del Hospital Barros Luco-Trudeau con múltiples lesiones verruciformes ubicadas en margen y cara dorsal de lengua, cara interna de ambas mejillas y labio inferior. Se realizó escisión quirúrgica de las lesiones de labio, cara dorsal de lengua y cara interna de mejilla del lado derecho, obteniéndose el diagnóstico histopatológico de condiloma. Tras 2 meses de realizar la cirugía se obtuvo recurrencia. La recurrencia de las lesiones puede originarse por la recrudescencia del virus latente adyacente al lecho quirúrgico y, por ello, deben considerarse otras alternativas de tratamiento. Por el impacto en la función, estética, potencial de contagio y malignización, es necesario su tratamiento.

ABSTRACT: The objective of this study was to report a clinical case in which surgical management of multiple condylomas in the oral mucosa was performed in a patient infected by Human Immunodeficiency Virus (HIV) who is under highly active antiretroviral therapy (HAART). A 58-yearold man, under HAART for 17 years for HIV infection, was admitted at the Maxillofacial Surgery Service at the Hospital Barros Luco-Trudeau as he was experiencing multiple verrucous lesions located on the lateral margin and dorsum of the tongue, as well as on the inner face of both cheeks and the lower lip. A surgical excision of the lesions on the lip, dorsum of the tongue and inner face of the right cheek was performed, where the histopathological diagnosis of condyloma was obtained. There was a recurrence two months after surgery. Recurrence of the lesions may be due to the recrudescence of the latent virus adjacent to the surgical bed and, therefore, other treatment alternatives should be considered. Treatment is necessary due to the impact on the function, aesthetics, and the potential to become contagious and malignant.

Tongue lesions and anomalies in a sample of Yemeni dental patients: a cross-sectional study

Background: Tongue examination helps considerably in diagnosing the underlying health state of the patient, especially in the cases of chronic diseases. The aim of this study is to determine the prevalence and association of tongue lesions with risk factors among Yemeni dental patients. Materials and methods: An oral medicine specialist examined all 713 patients attending the dental polyclinics at the University of Sciences and Technology (Sana’a, Yemen). The examination sheet was designed to include information related to patient characteristics, medical history, dental history, habits, and tongue lesions. Results: The prevalence of tongue lesions among the examined participants was 76.5 percent. The prevalence rate was 83.4 percent for males and 69.2 percent for females. Fissured tongue was the most common condition. Logistic regression analysis indicated that older age (p<0.001), gender (p=0.007), khat chewing (p<0.001), and smoking (p=0.001) were associated with fissured tongue; gender (p<0.001), khat chewing (p<0.001), and smoking (p<0.001) were associated with hairy tongue; and older age (p<0.001), khat chewing (p=0.001), and smoking (p=.021) were associated with coated tongue. Conclusion: The prevalence of tongue lesions among this sample of Yemeni population was 76.5 percent; fissured tongue and hairy tongue were the most prevalent lesions. Khat chewing, smoking, and older age were the associated risk factors for many of studied lesions and anomalies.

Coexistence of resistance to thyroid hormone and ectopic thyroid: ten-year follow-up

SUMMARY Resistance to thyroid hormone (RTH) coexisting with ectopic thyroid is rare. Here we report a case of RTH with ectopic thyroid. A ten-year-old girl had been misdiagnosed as congenital hypothyroidism and treated with levothyroxine since she was born. Ten-year follow-up showed that the elevated thyrotropin was never suppressed by levothyroxine and no signs indicating hyperthyroidism or hypothyroidism despite elevated FT3 and FT4 levels. Therefore the girl developed no defects in physical and cognitive development. Pituitary adenoma was excluded by magnetic resonance imaging. Ultrasonography did not find the thyroid gland in the normal place, while the thyroid scan found a large lingual thyroid gland. The octreotide inhibition test showed a reduction in thyrotropin by 41.98%. No mutation was detected in the thyroid hormone receptor (THR) β, THRα, thyrotropin receptor (TSHR), and GNAS1 genes. To our knowledge, it is an interesting RTH case coexisting with lingual thyroid.

Case report: tongue gangrene and oropharyngeal carcinoma

Gangrene of the tongue is a condition rarely described in the literature. It generally occurs in association with temporal arteritis and other vasculitides. We described a rare case of tongue necrosis associated with oropharyngeal carcinoma. A 67-male patient, previously submitted to exclusive radiotherapy for a squamous cell carcinoma of the tonsillar region, was admitted to our service with high dysphagia. Computed tomography showed circumferential swelling of the oropharynx, with areas of diffuse contrast uptake and significant reduction of the vascular flow at this level, especially venous return. About 6 months after the onset of symptoms, he was submitted to an urgent tracheostomy for airway obstruction. Then, about 1 month after tracheotomy, the neck skin became ecchymotic, congested, and he started with profuse oropharyngeal bleeding and congestion and thrombosis signs in the tongue. To our knowledge, this entity has not been yet described in the literature (AU)

Rendu-Osler-Weber syndrome: dermatological approach

The Rendu-Osler-Weber syndrome is a rare systemic fibrovascular dysplasia, recognized by mucocutaneous telangiectasias, arteriovenous malformations, epistaxis and family history. Recurrent bleeding, hypoxemia, congestive heart failure, portosystemic encephalopathy, and symptoms related to angiodysplasia of the central nervous system may occur. Since the treatment is based on supportive measures, early recognition is of utmost importance. This article reports the case of a 53-year-old male patient who presented telangiectasias on fingers, oral cavity and nasal mucosa for 10 years, with a history of recurrent epistaxis of varying severity since childhood. Mother, sister and daughter have similar lesions.
