Soft Tissue Chondroma: Two Cases Report and Literature Review

Abstract

Introduction: Soft tissue chondroma is a very rare, slow progressing, benign tumor. It has a specific tendency for hands and feet. It can exhibit worrisome radiographic and histologic features mimicking chondrosarcomas. Case 1: A 54-year-old man was presented with a big mass in the left thigh. At magnetic resonance imaging (MRI), the lesion exhibited a heterogeneous pattern, localized in muscle without infiltration. Open biopsy was performed showed a soft tissue chondroma. Case 2: A 40 years old man presented with a hard mass on the right iliac fossa. TDM showed a well circumscribed soft tissue mass with a heterogeneous pattern. Histological assessment of the resected specimen confirmed a soft tissue chondroma. Conclusion: Soft tissue chondroma is a very rare benign tumor. In our case, the tumor presented with an unusual location and radiological appearance, suggesting a malignant process. The diagnosis was rectified thanks to pathological examination.

Extra skeletal soft tissue chondroma (ESSC) of right thumb- a benign tumour diagnosed by FNAC – a rare case report

“…X-Ray of antero-posterior, lateral views right hand showed normal bony skeleton with multiple irregular cartilaginous masses without any connection and bony erosions (Fig II without any existing lesions near tendon sheath or tendon, joint capsule or periosteum. Lesion may arise from fibrous stroma but not from mature cartilaginous or osseous tissue 2,3,5 and can be differentiated from juxtacortical or periosteal chondroma which is a benign tumor located between the bone and periosteum 2,3 . Clinically it is slowly growing usually painless small single or multiple nodules smooth to irregular lobulated soft tissue mass and often ignored by the patients.…”
