Giant Cell Tumor is a benign but aggressive osteolytic neoplasm, richly vascularized and with numerous giant cells with osteoclastic activity. It often occurs in long bone epiphyses and rarely affects the ribs (about 1% of cases). The presentation of this tumor in the anterolateral portion of the costal arch is extremely rare compared to the posterior region. The present report describes the case of a patient who had a painful tumor on the left anterolateral chest wall, of insidious growth. Imaging exams revealed an insufflating lesion in the 10th left costal arch (4.2 x 3.5 cm), with areas of interior calcification. The patient underwent surgical treatment, with wide resection of the tumor, comprising 9th, 10th and 11th ribs and a portion of the diaphragm. The definitive diagnosis of giant cell tumor was made by immunohistochemistry of the surgical specimen. This report provides a basis for studying the therapeutic possibilities of this pathology in atypical locations, reinforcing that the block excision with wide margins of these tumors promotes a lower chance of local recurrence.
