Dermoscopy is a valuable method for improving the diagnostic accuracy of pigmented skin lesions. Specific dermoscopic criteria have been described for differentiating pigmented spindle and/or epithelioid cell nevi (SECN; Spitz nevi and Reed nevi) from cutaneous melanomas. In the present study, we report an additional dermoscopic feature of SECN, namely a distinctive type of pigment network, described as superficial black network, which was observed in 10.5% of SECN. Histopathologically, this network corresponds to focal areas of pigmented parakeratosis, producing a black reticulated appearance on the horizontal plane.
