ABSTRACT
Dentro de las neoplasias más frecuentes de tejidos blandos mesenquimáticos, el lipoma es el de mayor frecuencia. A nivel de cabeza y cuello, su incidencia es inferior, siendo de 2 a 4 por ciento. En la cavidad bucal, la ubicación más usual es en la lengua. Histológicamente, se observan adipocitos separados por tabiques fibrosos. El diagnóstico diferencial se realiza con tumor de células granulares, neurofibroma, fibroma traumático y malformaciones de las glándulas salivales. En el siguiente artículo se describirá un caso clínico con su técnica quirúrgica.
Among the most frequent neoplasms of soft mesenchymal tissues, lipoma is the most frequent. At head and neck level, the incidence is lower, being 2 to 4 percent. In the oral cavity, the most usual location is on the tongue. Histologically, adipocytes are seen separated by fibrous septa. The differential diagnosis is made with granular cell tumor, neurofibroma, traumatic fibroma and malformations of the salivary glands. The following article will describe a clinical case with its surgical technique.

INTRODUÇÃO: Os lipomas são os tumores mesenquimais benignos mais frequentes na população. Para ser considerado gigante, deve apresentar pelo menos 10 cm em uma de suas dimensões ou pesar ao menos 1.000g. O objetivo do trabalho é analisar uma série de casos de lipomas gigantes atendidos em nosso serviço. MÉTODO: Análise retrospectiva de prontuários e registros anatomopatológicos dos diagnósticos de lipomas submetidos a tratamento cirúrgico no período de janeiro 2003 a janeiro 2010. RESULTADOS: Foram avaliados 14 pacientes, com média de idade de 52,3 anos (33-72) e tempo médio de evolução até o tratamento de 4,4 anos (seis meses - 20 anos); 64% dos casos não apresentavam sintomas. Todos os pacientes foram submetidos à ressecção cirúrgica da neoplasia. O peso médio das peças foi de 3,8 kg (512 g - 22 kg) e o tamanho médio no maior eixo foi de 27,5 cm (15-66 cm). Foram observadas complicações pós-operatórias em 42% dos casos. CONCLUSÃO: Observamos períodos prolongados de evolução até o tratamento, mesmo em casos com lesões de grande volume. A exérese cirúrgica aberta deve ser considerada o tratamento de eleição para estes tumores.
INTRODUCTION: Lipomas are the most common benign mesenchymal tumors worldwide. To be considered giant, they must be at least 10 cm in one of its dimensions or weigh at least 1,000 g. The objective of this study is to analyze a series of cases of giant lipomas seen in our practice. METHOD: We conducted a retrospective analysis of the medical and anatomopathological records of patients diagnosed with lipomas who underwent surgery between January 2003 and January 2010. RESULTS: We evaluated 14 patients with a mean age of 52.3 years (range, 33-72 years) and a mean evolution time until treatment of 4.4 years (range, 6 months to 20 years); 64% of cases presented no symptoms. All patients underwent surgical tumor resection. The average weight of the pieces was 3.8 kg (range, 512 g to 22 kg), while the average length of the longest axis was 27.5 cm (range, 15-66 cm). Postoperative complications were observed in 42% of cases. CONCLUSION: We observed prolonged periods of evolution until treatment, even in cases of large-volume lesions. Open surgical excision should be considered the treatment of choice for these tumors.

Allodynia is the sensation of pain due to non-painful stimuli. It usually occurs due to destructive lesions of the spinal cord or peripheral nerves. Allodynia following intradural lipoma surgery has been reported previously. We herein report a case of allodynia developed after microsurgical caudal lipoma excision without associated spinal cord injury.

Introdução: Contrastando com o fato de que os lipomas são tumores mesenquimais muito comuns, a variante subfascial é bastante rara. Esta é subdividida em intermuscular eintramuscular. O tipo intermuscular é o menos comum. Os lipomas gigantes também são raramente encontrados e são caracterizados por medir, no mínimo, 10 centímetros em uma dasdimensões ou pesar ao menos 1000 gramas. Relato do caso: No presente artigo, relatamos o caso de uma paciente apresentando um lipoma intermuscular gigante localizado na coxa.
Introduction: Despite the fact that lipomas are very common mesenchymal tumors, the subfascial variant is quite rare. It is subdivided into intermuscular and intramuscular. The intermuscular type is less common. Giant lipomas are also rarely found and are characterizedby measuring at least 10 centimeters in one dimension or weigh at least 1000 grams. Case report: In this article, we describe the case of a patient presenting a giant intermuscular lipoma located in the thigh.
