Abstract

ABSTRACT: A retrospective study was performed to describe the demographic and clinicopathological characteristics of cases of vascular anomalies in a Brazilian population. The data of cases diagnosed as vascular anomalies over a period of 46 years, were retrieved from the archives of the Pathological Anatomy Service of the Department of Dentistry of Federal University of Rio Grande do Norte. Information about sex, age, race, diagnosis, location, and clinical characteristics was extracted. A database was created for analysis in the SPSS system and description of the results. The sample consisted of 597 cases categorized as follows: pyogenic granuloma (n = 454), infantile hemangioma (n = 57), vascular malformation (n = 37), lymphangioma (n = 20), hemangiolymph angioma (n = 10), vascular thrombus (n = 7), hemangio endothelioma (n = 5), angiofibroma (n = 1), hemangioendothelio sarcoma (n = 1), and Kaposi sarcoma (n = 5). Overall, there was a predominance of females (64.2 %), white race (54.2 %), and patients in the 3rd and 4th decades of life. Most cases affected the gingiva/ ridge (44.75 %), had a red/reddish color (60.07 %), sessile implantation (52.4 %), soft consistency (52.7 %) and nodular appearance (53, 9 %), and were non-hemorrhagic (51.3 %) and asymptomatic (76.6 %). The demographic and clinicopathological findings obtained for most of the vascular lesions analyzed are similar to those reported in published studies involving other populations. Knowledge of the particularities of these disorders is important for appropriate diagnosis and treatment decision.

RESUMEN: Se realizó un estudio retrospectivo para describir las características demográficas y clínico-patológicas de casos de anomalías vasculares en una población brasileña. Los datos de los casos diagnosticados como anomalías vasculares durante un período de 46 años, fueron obtenidos de los archivos del Servicio de Anatomía Patológica del Departamento de Odontología de la Universidade Federal de Rio Grande do Norte. Se analizó la información de sexo, edad, raza, diagnóstico, ubicación y características clínicas, y se creó una base de datos para análisis en el sistema SPSS y descripción de los resultados. La muestra consistió de 597 casos categorizados de la siguiente manera: granuloma piógeno (n = 454), hemangioma infantil (n = 57), malformación vascular (n = 37), linfangioma (n = 20), hemangiolinfangioma (n = 10), trombo vascular (n = 7), hemangioendotelioma (n = 5), angiofibroma (n = 1), hemangioendoteliosarcoma (n = 1) y sarcoma de Kaposi (n = 5). En general predominaron las mujeres de raza blanca (64,2 %), (54,2 %), y pacientes en la 3ª y 4ª década de la vida. La mayoría de los casos afectaban la encía / cresta (44,75 %), tenían un color rojo / rojizo (60,07 %), implantación sésil (52,4 %), consistencia blanda (52,7 %) y apariencia nodular (53,9 %), no hemorrágicos (51,3 %) y asintomáticos (76,6 %). Los hallazgos demográficos y clínico-patológicos de la mayoría de las lesiones vasculares analizadas son similares a los reportados en la literatura de otras poblaciones. El conocimiento de las particularidades de estos trastornos es importante para el diagnóstico y la decisión de tratamientos adecuados.

Hemangiomas and vascular malformations in infants and children: a classification based on endothelial characteristics.

J Mulliken, J Glowacki (1982)

Forty-nine specimens from a variety of vascular lesions were analyzed for cellular characteristics. Two major categories of lesions emerged from this investigation: hemangiomas and vascular malformations. This classification and its implications are justified by several considerations. Hemangiomas in the proliferating phase (n = 14) were distinguished by (1) endothelial hyperplasia with incorporation of [3H]thymidine, (2) multilaminated basement membrane formation beneath the endothelium, and (3) clinical history of rapid growth during early infancy. Hemangiomas in the involuting phase (n = 12) exhibited (1) histologic fibrosis and fat deposition, (2) low to absent [3H]thymidine labeling of endothelial cells, and (3) rapid growth and subsequent regression. The endothelium in hemangiomas had many characteristics of differentiation: Weibel-Palade bodies, alkaline phosphatase, and factor VIII production. Vascular malformations (n = 23) demonstrated no tritiated thymidine incorporation and normal ultrastructural characteristics. These lesions were usually noted at birth, grew proportionately with the child, and consisted of abnormal, often combined, capillary, arterial, venous, and lymphatic vascular elements. This cell-oriented analysis provides a simple yet comprehensive classification of vascular lesions of infancy and childhood and serves as a guide for diagnosis, management, and further research.

Oral pyogenic granuloma: a review.

Hamid Jafarzadeh, Majid Sanatkhani, Nooshin Mohtasham (2006)

Pyogenic granuloma is one of the inflammatory hyperplasias seen in the oral cavity. This term is a misnomer because the lesion is unrelated to infection and in reality arises in response to various stimuli such as low-grade local irritation, traumatic injury or hormonal factors. It predominantly occurs in the second decade of life in young females, possibly because of the vascular effects of female hormones. Clinically, oral pyogenic granuloma is a smooth or lobulated exophytic lesion manifesting as small, red erythematous papules on a pedunculated or sometimes sessile base, which is usually hemorrhagic. The surface ranges from pink to red to purple, depending on the age of the lesion. Although excisional surgery is the treatment of choice for it, some other treatment protocols such as the use of Nd:YAG laser, flash lamp pulsed dye laser, cryosurgery, intralesional injection of ethanol or corticosteroid and sodium tetradecyl sulfate sclerotherapy have been proposed. Because of the high frequency of pyogenic granuloma in the oral cavity, especially during pregnancy, and necessity for proper diagnosis and treatment, a complete review of published information and investigations about this lesion, in addition to knowledge about new approaches for its treatment is presented.

Prospective study of infantile hemangiomas: demographic, prenatal, and perinatal characteristics.

K Horii, , Anne W Lucky … (2007)

To characterize demographic, prenatal, and perinatal features of patients with infantile hemangiomas and to determine the importance of these factors in predicting rates of complication and treatment. We conducted a prospective study at 7 U.S. pediatric dermatology clinics. A consecutive sample of 1058 children, aged 12 years and younger, with infantile hemangiomas was enrolled between September 2002 and October 2003. A standardized questionnaire was used to collect demographic, prenatal, perinatal, and hemangioma-specific data. National Vital Statistic System Data (NVSS) was used to compare demographic variables and relevant rates of prenatal events. In comparison with the 2002 United States National Vital Statistics System birth data, we found that infants with hemangiomas were more likely to be female, white non-Hispanic, premature (P < .0001) and the product of a multiple gestation (10.6% versus 3.1%; P < .001). Maternal age was significantly higher (P < .0001), and placenta previa (3.1%) and pre-eclampsia (11.8%) were more common. Infants with hemangiomas are more likely to be female, white non-Hispanic, premature, and products of multiple gestations. Prenatal associations include older maternal age, placenta previa, and pre-eclampsia. No demographic, prenatal, and perinatal factors predicted higher rates of complications or need for treatment.
