Abstract

We report a case of Giant Cell Tumor (GCT) arising from anterior are of first rib along with literature review which was treated with excision of rib through its normal margin along with tumor mass. GCT of rib is rare and if found mostly arises from the posterior aspect. However, GCT should be considered as differential diagnosis when bony mass is present in the anterior are of rib. It poses surgical challenge for excision because of the delicate and vital neurovascular structures passing above it between clavicle and first rib.

Highlights

Giant Cell Tumor (GCT) is found most often at the end of skeletally mature long bones essentially arising from epiphysis
The lesion is of uncertain cell origin and comprises of 5% of all bony neoplasm according to Mayo clinic series
We are reporting a rare presentation of GCT arising from anterior arc of first rib because of its rarity and challenge for its surgical dissection from adjacent vital neurovascular structures while excision of tumor mass

Summary

Introduction

Giant Cell Tumor (GCT) is found most often at the end of skeletally mature long bones essentially arising from epiphysis. The lesion is of uncertain cell origin and comprises of 5% of all bony neoplasm according to Mayo clinic series. The rib is rare site for GCT with an incidence of less than 1% of all GCT.[1] The cases reported earlier in the literature, most were located in the posterior arc i.e. head and tubercle of rib.[2,3] We are reporting a rare presentation of GCT arising from anterior arc of first rib because of its rarity and challenge for its surgical dissection from adjacent vital neurovascular structures while excision of tumor mass.
