Background: Sebaceous hyperplasia is a benign but clinically and cosmetically unappealing lesion. Historical treatments include cauterization, cryotherapy, chemical ablation, and surgical removal, all of which increase the risk for permanent post-operative adverse effects. The pulsed-dye laser (PDL) offers a safe and effective approach to the treatment of sebaceous hyperplasia in Fitzpatrick sk...
Cyclosporin and azathioprine are immunosuppressive drugs, used widely in kidney transplant patients. A significant association between immunosuppressive therapy and multiple warts was described several years ago. There are also some reports of sebaceous gland hyperplasia in kidney transplant patients receiving cyclosporin. We report herein a 57-year-old woman who developed multiple warts on her...
Terim Kapakin K.A., F. Bozkurt, R. Haziroğlu: Sebaceous Adenocarcinoma in a Cat. Acta Vet. Brno 2008, 77: 123-125. In this study, the sebaceous gland adenocarcinoma was presented in the external auditory canal of a 10-year-old female tabby cat. There were three tumoural masses located macroscopically in the external auditory canal in the dimensions of 0.2 × 0.5, 0.3 × 0.5, and 0.1 × 0.1 cm, and...
Human WNT10A mutations are associated with developmental tooth abnormalities and adolescent onset of a broad range of ectodermal defects. Here we show that β-catenin pathway activity and adult epithelial progenitor proliferation are reduced in the absence of WNT10A, and identify Wnt-active self-renewing stem cells in affected tissues including hair follicles, sebaceous glands, taste buds, nails...
The newly discovered endocannabinoid system (ECS; comprising the endogenous lipid mediators endocannabinoids present in virtually all tissues, their G-protein-coupled cannabinoid receptors, biosynthetic pathways and metabolizing enzymes) has been implicated in multiple regulatory functions both in health and disease. Recent studies have intriguingly suggested the existence of a functional ECS i...
Sebaceous adenocarcinoma is a rare adnexal tumor that can affect the skin and is divided into ocular, a more common form and extra ocular, of a rarer occurrence. We report the case of a patient diagnosed with Acquired Immune Deficiency Syndrome (AIDS) who developed an extra ocular, bulky and fast-growing sebaceous adenocarcinoma on the face. The literature has suggested that transplanted patien...
BACKGROUND The purpose of this study was to describe the incidence of nodal disease in sebaceous carcinoma and its impact on survival. METHODS Data from the 17 registries of the Surveillance, Epidemiology, and End Results (SEER) database was retrospectively collected for sebaceous carcinoma from 1973 to 2007. Information on location, histologic grade, stage of disease, and survival was gather...
The sterol A7-cholestenol constitutes a large proportion of the total sterols of rat and mouse skin (5, 7, 18). Whereas the concentration of this sterol is not altered by such factors as diet, metabolic rate (7), and ultraviolet light (13), it decreases rapidly following the application of carcinogenic hydrocarbons to mouse skin (5). This decrease coincides with destruction of the sebaceous gla...
The pathophysiology of acne vulgaris depends on active sebaceous glands, implying that selective destruction of sebaceous glands could be an effective treatment. We hypothesized that light-absorbing microparticles could be delivered into sebaceous glands, enabling local injury by optical pulses. A suspension of topically applied gold-coated silica microparticles exhibiting plasmon resonance wit...
DEAR EDITOR, Skin diseases affect a significant percentage of the population and are often the result of a complex interplay between autoimmune dysregulation, and abnormal epidermal differentiation and proliferation. Origins may be genetic and/ or environmental, and while no complete cure exists for conditions such as psoriasis, a range of treatments, including reti-noids and antibodies against...
