Abstract :

C hondroblastoma is a benign but locally destructive lesion that was first described in 1942 by Jaffe and Lichenstein. These are rare tumours, the incidence being less than 1% of all primary bone tumours. Males are affected more often than females, the ratio being approximately 1.7:1. Because of its rarity and resemblance with a malignant tumor it poses a clinical and radiological challenge to the diagnosis. Methods: A 17-year old female presented with swelling of the left scapula since 3 months. She gives history of progressive increase in the swelling associated with pain and tenderness. No history of trauma or infection. No history of loss of appetite or loss of weight. On examination there was a firm, large, mildly tender mass located in the lower part of left scapula. Margins were ill defined and gradually merging with rest of scapula. Swelling was mobile along with scapula. Her shoulder movements were normal. Plain radiograph showed a huge expansile lesion in the lower part of scapula with multicystic and sclerotic changes. CT scan of scapula showed expansile osteolytic lesion with destruction of left scapula involving body with soft tissue components and cystic areas, thinning and erosion of overlying cortex and narrow zone of transition. The lesion measures about 6.1*4.2*5.5 cms. No evidence of calcification was seen within the lesion. MRI with contrast showed complex cystic mass lesion of left scapula body infraspinus location. Lesion showed soft tissue intensity solid component and cysts show fluid-fluid level layering. Multiple thick septation and loculations were noted. Results: Through a posterior shoulder approach (Das Gupta?s approach) we completely excised the tumor along with partial removal of scapula. The whole specimen was sent for histopathological examination. Biopsy confirmed the diagnosis of chondroblastoma. Patient had an uneventful post operative recovery with painless range of movements of shoulder. Conclusion: Herein, we describe a case of a chondroblastoma situated in the scapula of a 17 year-old female. This case is interesting because tumors of the scapula are rare and usually malignant
