Synovial sarcoma (SS) is a malignant mesenchymal neoplasm that is relatively common in the distal extremities. Primary SS of bone is an extremely rare finding. Here in this report, we present a 44-year-old male patient referred with bone and later bone fracture that was finally diagnosed with primary SS of thumerus. So far, 13 documented cases of primary SS of the bone have been reported. The current case is the second known case of primary SS of humerus. Our case was treated with both neoadjuvant and adjuvant chemotherapies associated with surgical tumor removal and prosthesis implantation. Follow-up of the case demonstrated significant remission but with late metastasis and subsequent advanced chemotherapy regimens.

Non-healing diabetic foot ulcer (DFU) is one of the main complications in diabetic patients. This case reported a 65-year-old male with a neuropathic ulcer in the right foot came to Ahwaz Wound Clinic after the wound had not healed with routine treatments. In addition to the routine treatment program, we used tropical ozone therapy and autohemotherapy (blood ozone therapy) for 2 months. Zinc supplementation (50 mg) was also administered daily during the treatment. The DFU was clearly healed with diminishing inflammation and wound closing, and there were no side effects. Additionally, the C-reactive protein level was obviously decreased during the treatment indicating effective suppression of infection. This way indicates a helpful new intervention approach to the treatment of DFU.
