[Non-melanomatous malignant skin tumors of the hand]

Non-melanomatous malignant skin tumors of the hand are the same as those observed on other parts of the body, but with specific characteristics of frequency, aetiology, site and sometimes misleading clinical features. The author analyses these characteristics in relation to precancerous tumors: solar keratoses, arsenical keratoses, radiation dermatitis, kerato-acanthomas, Bowen's disease and malignant tumors: basal cell, squamous cell and other rarer carcinomas. He then outlines the principles of surgical treatment with reference to anaesthesia, usually local or regional, and resection, whose extent and depth depend on the nature and site of the lesion.
