A rare case study of myxoid chondrosarcoma in 4th metacarpal hand

Abstract

Background: myxoid chondrosarcoma (MC) is a rare soft tissue tumor that typically affects the lower limbs of men between the ages of 50 and 60. EMC of the Metacarpals is rare of rarest with a high risk of local recurrence and distant metastasis. A planned surgical excision in sarcoma referral centers (SRCs) is mandatory to obtain the best outcome. The role of chemotherapy (CHT) and Radiotherapy (RT) on soft tissue chondrosarcoma is still under study. Case presentation: A 53-year-old male patient presented to our hospital with a history of swelling in the left hand for 6 months. Radiological and histological study reveals diagnosis of extra skeletal chondrosarcoma. Wide surgical excision was done using cryotherapy in form of liquid nitrogen. Biopsy was taken from the site and sent to immunohistochemistry which proved the diagnosis. A Kirschner wire embedded with polymethylmethacrylate cement was placed in defect site and checked for movements. imaging exams did not reveal distant metastasis or residual disease. Local radiotherapy was administered with a total dose of 50 Gy and adjuvant chemotherapy was given. No relapse occurred in a 12-months post-operative follow up. Conclusions: The case here described suggests the importance of patient’s management in SRCs.
