Leiomiossarcomas são neoplasias mesenquimais malignos geralmente encontrados no útero, no retroperitônio ou trato gastrointestinal. Porém, raramente ocorrem como tumor primário de pele. As pernas são locais mais acometidos. Descrevemos uma paciente do sexo feminino, 39 anos de idade, na qual apresentava um nódulo doloroso em perna direita há seis anos.
