Surface microscopy. A new approach to the diagnosis of cutaneous pigmented tumors.

摘要: Clinical guidelines for the diagnosis of pigmented lesions skin are not always reliable. Surface microscopy (SM) represents an interesting approach to this problem. For in vivo investigation, a stereomicroscope, glass slide, and immersion oil used. In present study, various criteria SM that cannot be discerned by naked eye correlated with histopathological structures step-sectioned specimens. Characteristic features such as pigment network, "black dots," or "irregular extensions" were found correspond particular histological findings. opens new dimension clinical morphology differential malignant melanomas, dysplastic nevi, nonmelanocytic neoplasms, facilitates more reliable preoperative assessment these lesions.
