A 40-year-old male presented to us with the chief complaints of swelling over the dorsum of left foot for the duration of 2 years and pain in that foot for 4 months. Swelling was insidious in onset and has progressively increased in size. Pain was mild to moderate in intensity, dull aching and continuous. It was relieved by taking medication and rest and aggravated by activity. There is no history of any constitutional symptoms or trauma. On physical examination, there was a localized ovoid shaped swelling 7 by 4 cm over the dorsum of the left foot opposing 1st and 2nd metatarsal area with well-defined margins. Swelling was tender on deep palpation, hard in consistency, and the overlying skin was free. Radiographs revealed an expansile osteolytic lesion of entire 1st metatarsal involving the articular surface of tarsometatarsal joint and metatarsophalangeal joint with impingement on 1st metatarsal and cortical thinning. The classical ‘soap bubble appearance’ was also present (). Fine needle aspiration cytology was done to confirm our diagnosis of GCT. According to Campanacci et al., the tumor was histologically graded as Grade II tumor (). A reconstructive surgery with fusion of the Cuneiform metatarsal and metatarsophalangeal joint was planned. The tumor was carefully removed with a cuff of normal tissue and the proximal and distal joints were inspected. There was no articular cartilage of the Cuneiform metatarsa joint. A fibular graft was taken and was inserted into the troughs created in medial cuineform and proximal phalanx and fixed with K-wire, both proximally and distally ( and ) []. The patient was given a below knee cast for three months postoperatively. Full weight bearing was started after 3 months. After 9 months of follow-up, the graft was well taken up and there were no signs of recurrence both clinically and radiologically ().
