Dermoscope is a very useful and non-invasive technique for diagnosis of pigmentary skin lesions. It helps in diagnosis of skin lesions like seborrheic keratosis , spitz nevus which may clinically simulate melanoma. It involves a complementary examination of pigmented lesions on the skin, increasing the chance of an accurate diagnosis of cutaneous melanoma. It is a relatively simple technique that can be carried out in a doctor's office, clinic, or hospital, with the use of a portable device (manual dermatoscope).In this article we are presenting the dermoscopic features of common hyper and hypopigmented skin lesions . The goal is to introduce this subject to those not yet familiar with it, in order to instigate and encourage the training and practice of this technique of growing importance for everyday usage.

THE PHYLLOID HYPOMELANOSIS is a defined as a distinct syndrome consisting of achromic phylloid skin lesions in combination with extracutaneous anomalies such as mental retardation , agenesis of corpus callosum , conductive hearing loss ,coloboma and various skeletal defects[1].
