Skin Tumors of the Hand and Upper Extremity

The skin of the upper extremity is composed of the epidermis, dermis, eccrine, apocrine and sebaceous glands, hair follicles, and nails. Benign and malignant tumors can arise from any of these structures. Diagnostic procedures and nonsurgical treatment are discussed as well as operative interventions for these tumors. Benign epidermal lesions may be successfully treated with superficial treatments. Benign dermal lesions usually require full-thickness intervention. The diagnosis, treatment, and prognosis for malignancies of the upper extremity including basal cell carcinoma, squamous cell carcinoma, and melanoma are presented at length, including the latest updates in management.
