Claimant had cancer in his arm and was unaware. He fractured his humerus while pulling a chain in the course of his employment. Abnormal bone was identified at the time of the fracture, and an extensive workup identified a sarcoma that had been asymptomatic up until the point of the injury. He underwent a complex surgery including an allograft reconstruction of the humerus and a shoulder replacement. The injury was deemed compensable and the Claimant was paid a 50% PPD to the upper extremity prior to settlement.  Claim settled for $85,000.
