Malignant Bone and Soft Tissue Tumors of Hand and Upper Limb-Case: Malignant Bone and Soft Tissue Tumors

Case: Malignant Bone and Soft Tissue Tumors

Pdf Summary

Case 1 involves a 66-year-old farmer with a soft tissue mass on the radial side of their right index finger. The mass is macerated, ulcerated, and measures 2x2 cm. Imaging shows a heterogeneous lesion in the soft tissues without involvement of bone or tendons. A biopsy confirms the diagnosis of invasive well-differentiated squamous cell carcinoma. The patient undergoes index ray resection and recovers well.<br /><br />In Case 2, a 15-year-old female presents with left wrist pain and no palpable mass. Radiographs reveal an expansile, lytic lesion involving the mid diaphysis of the third metacarpal with a cartilaginous matrix. An MRI confirms an expansile lesion with focal cortical breach and a small soft tissue component, suggesting an aggressive cartilaginous neoplasm. Because pathology may not be conclusive, due to similarities between enchondroma and low-grade chondrosarcoma, the lesion is excised with the placement of a structural intercalary iliac crest allograft. The pathology report confirms the diagnosis of chondrosarcoma arising from a pre-existing enchondroma. CT chest and bone scan are negative for metastasis, and the patient is advised to undergo regular monitoring with imaging.<br /><br />Overall, these two cases highlight the importance of timely diagnosis and appropriate management of malignant bone and soft tissue tumors.
