Description
Summary:Giant cell tumor (GCT) is a benign locally aggressive tumor with features of frequent recurrence and metastatic potential. GCT of small bones of hand and feet is rare with high recurrence and potential to metastasis. This study aims to provide a case report of GCT of the first metatarsal treated with wide excision, autologous fibular grafting, and fixation with locking plate. An 18-year-old male patient presented with progressive swelling over the dorsomedial aspect of foot for 1 year. Upon clinical examination, the swelling was firm with local signs suggestive of a benign bony tumor arising from the base of first metatarsal of the left foot. Radiology reveals an expansile osteolytic lesion arising from the base of 1st metatarsal with coarse septations and features suggestive of a benign bone lesion. A core biopsy was obtained under local anesthesia and histopathology report suggested a GCT. Surgical intervention by en bloc excision and reconstruction by fibular autograft and stabilized with a locking plate was done. The patient was given a below-knee cast for 6 weeks postoperatively. Full weight bearing was started after 6 weeks. At 12 months of follow-up, the graft was well taken up and there were no signs of recurrence both clinically and radiologically. GCT of 1st metatarsal is a rare entity with higher recurrence rate compared to conventional GCT. En bloc excision and autologous fibular graft with plate fixation are preferred treatment options.
