An Extensive Infiltrative Diffuse Tenosynovial Giant Cell Tumor in Both Compartments of the Forearm: A Case Report
Abstract
Diffuse tenosynovial giant cell tumors are relatively rare but second most common tumor effecting the synovial containing tissues. The study aim was to present a case involving a 40-year-old male patient with a complaint of a progressively enlarging swelling on the radial side of right wrist. On local examination, there was a bi-lobed swelling 7×9 and 6×5 cm on the dorsolateral and anterolateral aspect of right wrist respectively. Through Hennery’s modified approach tumor was exposed. It was extending from dorsolateral to anteromedial wrist encasing the flexors, extensor and abductor tendons of thumb and radial neurovascular bundle and adjacent wrist and finger flexors. The tumor surrounding the tendons was carefully removed, and carpal tunnel release was performed to address the tingling sensation. The patient managed was having lobulated diffuse type tumor involving the both flexor and extensor compartment. Better outcome, less morbidity and least chance of recurrence can be expected if the tumor had been operated earlier.
