简要总结
Existing methods of diagnosing and treating skin lesions are either surgical, which enables an histological diagnosis or destructive (electrodesiccation, liquid nitrogen, laser, caustics) with no possibility of obtaining histology. The ingredients of current formulations for in-vivo skin fixation (Mohs, Solcoderm) are unstable, inconvenient for application and painful - therefore their use was abandoned. The investigators will examine the safety of stable formalin-free formulations for in-vivo fixation of human skin lesions .These formulations were safe and had a rapid onset of fixation effect in in-vivo animal studies.
详细描述
The formulations are comprised of standard non-toxic laboratory chemicals that are used in various dermatological preparations.
Transition metal salts - Zinc chloride, zinc bromide, zinc iodide,zinc nitrate, zinc sulphate. copper chloride ,copper bromide, copper iodide, copper nitrate, copper sulphate.
Keratolytics - salicylic acid , lactic acid, nitric acid, pyruvic acid,oxalic acid, trichloro acetic acid, phenol, resorcinol,urea .
The solvents and penetration enhancers of the ingredients - Water, ethanol, dimethyl sulfoxide, propylene glycol, glycerol.
Patients with skin lesions that after clinical diagnosis are usually treated by dermatologists with destructive modalities without an histological evaluation will be included in the study. The clinical diagnoses include viral warts, seborrheic warts, skin tags, solar keratoses, fibromata and hemangiomata.
