Carpal tunnel syndrome secondary to neoplastic space-occupying lesion

This article presents a previously reported case of a 66-year-old woman with a mass on the volar aspect of her right wrist and a one-month history of right wrist pain. The importance of considering a wide range of causes for carpal tunnel syndrome when assessing a patient with persistent wrist pain and an associated mass is highlighted. The differential diagnosis of space-occupying lesions should include benign and malignant neoplastic etiologies in addition to non-neoplastic etiologies. The clinical features, diagnostic methods, and management options for a patient with carpal tunnel syndrome are presented and key distinctions between conventional and secondary carpal tunnel syndrome are discussed. Lipomas, schwannomas, and synovial sarcomas are discussed to showcase different neoplastic causes that may present as secondary carpal tunnel syndrome with an associated wrist mass as seen in this case. &nbsp
