Biology of Wound Healing
Abstract As the outer barrier to the environment, the skin is the organ most challenged by a range of external stress factors that can lead to cellular damage and barrier…
Fibrous and Fibrohistiocytic Proliferations of the Skin and Tendons
Abstract Fibrous and fibrohistiocytic proliferations of the skin and tendons comprise a heterogeneous group of both benign and malignant mesenchymal tumors. Predominant tumor cells are CD34 + fibroblasts, α-smooth muscle…
Electrosurgery
Abstract Modern electrosurgery encompasses a range of techniques by which high-frequency, alternating electrical current is applied to living tissues, resulting in superficial or deep coagulation or cutting of the skin….
B-Cell Lymphomas of the Skin
Abstract Primary cutaneous B-cell lymphomas (pCBCLs) are classified into 3 main categories: primary cutaneous marginal zone B-cell lymphoma (PCMZL), primary cutaneous follicle center lymphoma (PCFCL), and primary cutaneous diffuse large…
Lasers and Other Energy-Based Therapies
Abstract This chapter examines the use of laser, light and other energy-based devices for both medical and aesthetic purposes as related to the skin. Given the multiplicity of devices available,…
Ultraviolet Therapy
Abstract Phototherapy represents the use of ultraviolet (UV) radiation in the treatment of skin diseases. Currently, phototherapy encompasses irradiations with broadband UVB (290–320 nm), narrowband UVB (311–313 nm), 308 nm excimer laser, UVA1…
Radiotherapy
Abstract From a dermatologic perspective, the major role for radiotherapy is in the treatment of basal cell carcinomas and cutaneous squamous cell carcinomas (SCCs) that are not readily treatable by…
Photodynamic Therapy
Abstract Photodynamic therapy (PDT) is a unique, practical and effective therapeutic option for the treatment of actinic keratosis (AKs), superficial keratinocyte carcinomas, and a wide range of other conditions. Its…
Lasers and Other Energy-Based Technologies – Principles and Skin Interactions
Abstract Laser surgery is based upon precise tissue heating when optical energy is absorbed within the skin, and the heat is created exactly where light is absorbed by molecules called…
Cutaneous T-Cell Lymphoma
Abstract The term cutaneous T-cell lymphoma (CTCL) describes a heterogeneous group of neoplasms of skin-homing T cells that show considerable variation in clinical presentation, histologic appearance, immunophenotype and prognosis. CTCLs…
