ABSTRACT

Antecedents: Giant-cell tumors are usually solitary lesions that are typically benign; however, they can cause lung metastases in 3% of the patients. The main symptom is progressive pain initially related to physical activities, which eventually becomes more evident even while resting. Around 10 to 30% of patients with pathological fractures in the initial exploration tend to be aggressive. Radiographic findings include expansive lesions that can break the cortex; nevertheless, an intra-articular extension is rare, since the subchondral bone usually remains intact. Magnetic resonance is useful to define the extent of the lesion in both the bone and the soft tissues. The historical treatment consisted of the simple curettage of the lesion, although right now the Argon laser coagulator and cryotherapy can be used as alternative solutions, as well as bone cement to fill the cavity. Clinical case: This is the first case reported of a pelvic limb preservation surgery with internal hemipelvectomy at the «Hospital para el Niño de Toluca», which belongs to the Instituto Materno Infantil from the State of Mexico. It was performed in a nine-year-old female patient diagnosed with a giant-cell tumor in the left supra-acetabular region and ipsilateral ischiopubic branches, using external type A/O tutors.
