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.展开更多

Extra skeletal chondromas are relatively uncommon of which those in head and neck regions are rarely documented. Although the tongue is one of the most common sites of oral soft tissue chondroma, lingual chondromas are rare as evidenced by the fact that only 33 cases are identified in the review of literature till now. This report has the objective of presenting a rare case of lingual enchondroma in a 26-year-old male which was excised with no evidence of recovery during follow up. We have also tried to present a concise review of the relevant literature.展开更多
