The specialty covers specific conditions that encompass the skin, hair and nails, and is considered traditionally a branch of Internal Medicine. Dermatology also entails surgery because of skin cancers as well as superficial lumps and bumps. Superficial skin lesions can be either benign or malignant. These often require removal by surgery. Surgical excision is required, for example, for pre-malignant or cancerous lesions.
