Skin tumors can have an epidermal, melanocytic or mesodermal origin. Lesions frequently encountered in elderly patients include benign tumors such as seborrheic keratoses, lentigo, keratoacanthoma, epidermal cyst and sebaceous hyperplasia. Premalignant and malignant tumors that often occur in the elderly include actinic keratosis, Bowen's disease, basal cell carcinoma, squamous cell carcinoma and melanoma. Diagnosis depends on the tumor's characteristics and morphology, although in some cases biopsy is required. Treatment depends on the character of the lesion, its location and the patient's general condition and includes curettage, cryosurgery, chemosurgery, excision and radiotherapy.
皮肤肿瘤可起源于表皮、黑素细胞或中胚层。老年患者中常见的病变包括良性肿瘤，如脂溢性角化病、雀斑样痣、角化棘皮瘤、表皮囊肿和皮脂腺增生。老年人中常发生的癌前和恶性肿瘤包括光化性角化病、鲍恩病、基底细胞癌、鳞状细胞癌和黑色素瘤。诊断取决于肿瘤的特征和形态，不过在某些情况下需要进行活检。治疗取决于病变的性质、部位以及患者的一般状况，包括刮除术、冷冻手术、化学外科手术、切除术和放射疗法。
