STUDY Microscopic In Vivo Description of Cellular Architecture of Dermoscopic Pigment Network

Objective: To characterize the microscopic aspects of the dermoscopic pigment network in vivo, by means of confocal scanning laser microscopy. Design: Confocal imaging was performed on melano-cytic lesions characterized by pigment network at der-moscopy. Some confocal architectural and cytologic fea-tures, as observed at the dermoepidermal junction, were morphologically described and quantified by means of a dedicated program. Setting: University medical department. Study Population: We studied confocal images of 15 melanomas, 15 dermoscopic atypical nevi, and 15 com-mon nevi. Main Outcome Measures: Features referring to as-pect, size, regularity, homogeneity, and infiltration of der
