Tumor de células gigantes em falange proximal com metástase pulmonar: relato de caso e revisão de literatura / Giant cell tumor in proximal phalanx with pulmonary metastasis: case report and literature review

RESUMO

Trata-se de um relato de caso de tumor de células gigantes (TCG) em falange proximal de terceiro dedo da mão esquerda com metástase pulmonar. A paciente apresentava dor no dedo sem história prévia de trauma. Foram realizados exame clínico, estudo radiográfico e ressonância nuclear magnética. Feito o estudo histológico, a partir de biópsia incisional, com hipótese de TCG. Foi submetida à amputação do dedo, confirmando o diagnóstico pela microscopia da peça. A paciente foi acompanhada devido ao risco de metástase pulmonar, evidenciada em estudo radiográfico e tomografia computadorizada de tórax, sendo submetida à toracotomia. Desde então, houve melhora dos sintomas referidos no pré-operatório e ausência de recidiva local e novas metástases.

ABSTRACT

This is a case report on a giant cell tumor in the proximal phalanx of the third finger of the left hand, with pulmonary metastasis. The patient presented pain in the finger without any previous history of trauma. Clinical examination, radiographic imaging and magnetic resonance imaging were carried out. A histological evaluation was done from an incisional biopsy, taking the hypothesis of giant cell tumor. The patient underwent amputation of the finger and the diagnosis was confirmed by means of microscopy on the specimen. The patient was followed up because of the risk of lung metastasis, which was shown by radiographic examination and computed tomography on the chest, and thoracotomy was performed. Since then, there has been an improvement of the symptoms that had been reported preoperatively, and no local recurrence or new metastasis has been found.
