The clinical presentation is consistent with osteosarcoma. Treatment for this patient would consist of neoadjuvant chemotherapy, surgical excision with reconstruction, and adjuvant chemotherapy. Osteosarcoma is the most common primary sarcoma of bone. It usually occurs in children and young adults with the majority occuring in the second decade of life. Quan et al retrospectively reviewed 27 cases of peri-articular osteosarcoma, specifically looking for intra-articular involvement. They suggest that intra-articular involvement of osteosarcoma is very rare as articular cartilage serves as a good boundary to tumor expansion. Joint contamination from an incorrect surgical procedure is a much more likely cause of intra-articular extension. Figure B is a radiograph that shows a destructive, non-geographic, bone-forming lesion in the proximal humerus.Figure C shows the lesion is hot on bone scan. Figure D is an MRI concerning for intra-articular tumor contamination which would alter the surgical resection. Figure E is a histology slide that shows atypical malignant cells on a background of malignant osteoid.
