Sebaceous carcinoma is a rare, aggressive, malignant tumor derived from the adnexal epithelium of sebaceous glands. It may arise in ocular or extraocular sites and exhibits such a variety of histologic growth patterns and diverse clinical presentations that the diagnosis is often delayed for months to years. We discuss incidence as well as clinical, histologic, diagnostic, prognostic, and management issues of this aggressive neoplasm.
Despite the burgeoning options available for skin rejuvenation, the benefits of laser skin resurfacing in trained hands remains unequaled. This article will review the preoperative evaluation, lasers and techniques used, postoperative course, and possible complications.
Laser treatment of vascular birthmarks remains one of the more common applications of dermatologic lasers and is the treatment of choice for port-wine stains (PWS) and superficial capillary hemangiomas. Before the development of laser technology, these lesions were treated with radiation, surgical excision and grafting, cryosurgery, and camouflage with cosmetics or tattoos. All of these techniques produced unsatisfactory results or poor aesthetic outcomes. The development of the pulsed dye laser in the 1980s permitted selective photocoagulation and destruction of lesional blood vessels without damage to the surrounding normal skin, thereby producing dramatic clearing of PWS and hemangiomas with minimal risk of scarring.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
