Although this morphology is also the most frequent among nevi localized on the sole of the foot, we have observed a group of lesions in this location with a marked disproportion between width and length. This particular appearance has not been previously described, and it could be mistaken for malignancy. We present a series of 9 patients with elongated plantar nevi and discuss their main clinical, dermoscopic and histopathological features. Interestingly, all the lesions presented with a linear appearance, with a length greater than 7<span class="elsevierStyleHsp" style=""></span>mm. Although this measurement has been considered highly suggestive of suspicious malignant lesions in the literature, we have only found one melanoma among our cases. We would like to highlight the importance of this particular presentation of acral melanocytic nevus to avoid an incorrect diagnosis of malignancy.</p><p id="par0010" class="elsevierStylePara elsevierViewall">We describe the clinical and dermoscopic characteristics of nine patients with a clinical diagnosis of melanocytic sole nevi who presented between 2007 and 2013 at the Pigmented Lesion Unit of the Dermatology Department of the General Hospital of Alicante (<a class="elsevierStyleCrossRef" href="#fig0005">Fig. 1</a>). The dermoscopic evaluation was performed by DermLite Foto™ (3Gen, LLC, Dana Point, CA, U.S.A.) mounted on a digital camera (Canon G9 and G12™) and with a digital videodermoscope (MoleMax II™). Melanocytic lesions with suspicious clinical or dermoscopic features were excised and histopathologically evaluated and cases without evidence of malignancy underwent videodermoscopic follow-up. Characteristics of the cases are summarized in <a class="elsevierStyleCrossRef" href="#tbl0005">Table 1</a>.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><elsevierMultimedia ident="tbl0005"></elsevierMultimedia><p id="par0015" class="elsevierStylePara elsevierViewall">The cases included 4 men and 5 women, ranging in age from 10 to 49 years old (median age 21) and all were Caucasian. The median length nevus was 17<span class="elsevierStyleHsp" style=""></span>mm, while the median width was 3.1<span class="elsevierStyleHsp" style=""></span>mm. Dermoscopy showed a combination of various types of acral benign dermoscopic patterns (parallel furrow and typical fibrillar patterns) in 8 out of the 9 nevi (<a class="elsevierStyleCrossRef" href="#tbl0005">Table 1</a>). These melanocytic nevi without dermoscopic signs of malignancy were all closely monitored (every 6 months) by videodermoscopy without evidence of neoplastic transformation.

Congenital lesions usually show a larger diameter and are diverse in size, and they show more heterogeneous color and shape than acquired melanocytic nevi.

We do not know the pathogenesis of the particular morphology of the nevi in our series, but we hypothesize that the distribution of melanocytes following the lines of Blaschko on the acral skin could be responsible for this particular shape. These pigmented nevi showed variable dermoscopic findings, without any particular location on the sole. Although this larger size is regarded as a suspicious finding in itself, we suggest that nevi with this particular morphology are benign lesions in most cases when associated with typical dermoscopic criteria. We recommend the early extirpation of all suspicious nevi presenting a parallel ridge pattern of any size and morphology, and a close follow-up of elongated lesions over 7<span class="elsevierStyleHsp" style=""></span>mm in their maximum diameter with benign parallel furrow dermoscopic pattern (and its variants), until these particular melanocytic lesions have been better characterized.</p></span>" "pdfFichero" => "main.pdf" "tienePdf" => true "multimedia" => array:3 [ 0 => array:7 [ "identificador" => "fig0005" "etiqueta" => "Figure 1" "tipo" => "MULTIMEDIAFIGURA" "mostrarFloat" => true "mostrarDisplay" => false "figura" => array:1 [ 0 => array:4 [ "imagen" => "gr1.jpeg" "Alto" => 1022 "Ancho" => 1301 "Tamanyo" => 187648 ] ] "descripcion" => array:1 [ "en" => "<p id="spar0005" class="elsevierStyleSimplePara elsevierViewall">Clinical (A, B) and dermoscopic findings (C, D) of 2 of the 9 longitudinal nevi on the sole.</p>" ] ] 1 => array:7 [ "identificador" => "fig0010" "etiqueta" => "Figure 2" "tipo" => "MULTIMEDIAFIGURA" "mostrarFloat" => true "mostrarDisplay" => false "figura" => array:1 [ 0 => array:4 [ "imagen" => "gr2.jpeg" "Alto" => 1006 "Ancho" => 1301 "Tamanyo" => 307327 ] ] "descripcion" => array:1 [ "en" => "<p id="spar0010" class="elsevierStyleSimplePara elsevierViewall">(A) One melanoma <span class="elsevierStyleItalic">in situ</span> was found among the 9 reported lineal nevi.
