title: Carpal tunnel syndrome secondary to Masson's tumour.
abstract: We present a case of a Masson's tumour causing carpal tunnel syndrome. Space occupying lesions should be considered as a differential in refractory cases of carpal tunnel syndrome, especially those in whom the symptoms are dynamic. Once radiological investigation confirms such a diagnosis, we advocate surgical excision, as malignancy can only be excluded via histological examination.
