ABSTRACT

Granulomas de células gigantes (GCCG) são lesões benignas intra-ósseas proliferativas. Estas lesões podem aparecer na região anterior da maxila ou da mandíbula, porém mais frequentemente encontradas na mandíbula. A etiopatogenia permanece desconhecida, no entanto, alguns autores consideram como uma resposta reparadora, ao invés de uma condição neoplásica. Clinicamente, o CGCG é assintomático, podendo causar expansão com desvio ou a proliferação da cortical óssea. Esta condição é geralmente unifocal. A remoção cirúrgica é, na maioria dos casos, o tratamento de escolha. Embora, os métodos de tratamento não-cirúrgicos, tais como injeções intralesionais de corticoesteróides, administração sistêmica de calcitonina e interferon foram relatados. Este artigo descreve as características radiográficas de um CGCG extenso na região anterior mandibular em um paciente de 09 anos de idade. O tratamento incluiu ressecção óssea com substituição por tíbia e aplicação de fatores de crescimento ósseo.


Central giant cell granulomas (CGCG) are benign intraosseous proliferative lesions. Usually located are at the anterior region of the maxilla ormandible, although are more frequently found in the mandible. Etiopathogenesis of these lesions has remained unknown, however, some consider them as reparative response rather than neoplastic condition. Clinically CGCG present as asymptomatic, with expansive swelling causing deviation or proliferation of cortical bone. This condition is usually unifocal. Surgical removal is often the preferred treatment. Although nonsurgical treatment methods, such as intralesional corticosteroid injections, systemic calcitonin and interferon have been reported. This article describes the radiographic features of a large CGCG in the anterior mandibular region seen in a9 year-old patient. Treatment of this lesion included resection of the anterior region of the mandible and replacement by tibia with bone growth factors.

ABSTRACT

El granuloma reparativo de células gigantes (GRCG) es un proceso reactivo agresivo, que aparece con mayor frecuencia en los sectores anteriores de la mandíbula y el maxilar, en niños y adolecentes jóvenes. Constituye el 1 por ciento de las lesiones óseas tumorales. Existe una considerable controversia acerca de si son lesiones benignas o reactivas; también desde el punto de vista de su origen, de sus características clínicas e histológicas, así como su terapéutica. En octubre de 2007 acudió un caso a consulta externa de Cirugía Maxilofacial del Hospital Pediátrico Universitario Juan M Márquez, con una lesión diagnosticada como GRCG agresivo, la cual provocó gran deformidad facial y osteólisis del cuerpo mandibular. Se realizaron exámenes físicos, complementarios e iconopatográfico. Se ejecutó tratamiento quirúrgico y análisis de la pieza. La paciente no tuvo alteraciones estéticas ni funcionales. Hubo ausencia de recidiva, luego de 30 meses de seguimiento. Se revisó la literatura más reciente en los sitios Med Line, Lilac, Google, con las palabras clave granuloma reparativo de células gigantes, en inglés y español, para comparar nuestros procederes y resultados con otros reportes(AU)


The giant cells reparative granulomas (GCRG) is a reactive and aggressive process appearing more frequently in anterior sector of mandible and maxilla in children and young adolescents accounting for the 1 percent of tumor bone lesions. There is a considerable controversy if they are benign or reactive lesions from the point of view of its origin, from its clinical and histological features as well as therapeutical. This is the case of a patient seen in external consultation of Maxillofacial Surgery of the Juán Manuel Márquez Children and University Hospital at October, 2007 in whom an extent lesion diagnosed as an aggressive GCRG provoked a facial deformity and osteolysis of mandibular body. Complementary, physical and iconopathographic examinations were made as well as surgical treatment and analysis of this sample. Patient has neither aesthetic alterations nor functional. There was no relapse after 30 months of follow-up. We made a review of more update literature in Med Line, Lilac and Google websites with the giant cells reparative granulomas as key words in English and Spanish languages, to compare our procedures and results with other reports(AU)
