Resumo

Lipomas são tumores bem definidos, de tecido adiposo, presentes no tronco ou nas extremidades, e que ocorrem em pacientes adultos. Esses tumores geralmente se desenvolvem sem dor e de forma insidiosa, podendo, no entanto, comprimir estruturas adjacentes. Este trabalho objetiva descrever o caso de uma paciente do sexo feminino, de 68 anos, com lipoma gigante localizado na face hipotenar, com manifestação de compressão dos nervos digitais palmares comuns, do nervo ulnar, e do músculo abdutor do V dedo. Como sintoma, ela apresentava quadro de dor moderada na face hipotenar, sem sinal de Tinel, e sem alterações da motricidade ou sensibilidade dos dígitos inervados pelo nervo ulnar. Os lipomas podem apresentar variada gama de características histológicas, e o diagnóstico diferencial pode incluir tumores malignos. O exame de imagem pode auxiliar no diagnóstico, o qual é confirmado por meio de estudo histopatológico. Para o presente caso, conforme preconizado na literatura, foi realizado um procedimento cirúrgico para a ressecção do tumor, que resultou no controle dos sintomas.
