Cutaneous endometriosis is a rare manifestation of endometriosis, representing 0.5% to 1% of all endometriosis cases. It can be divided into primary and secondary, when appearing spontaneously or after a surgical procedure, when it is mostly found on surgical scar tissue. Some etiologies were proposed, but none of them could entirely explain the appearance of the tumor. Differential diagnosis includes melanoma, metastatic nodule, keloid and pyogenic granuloma. Dermoscopic features are not yet well established, but there are some characteristics that suggest the diagnosis. Treatment is surgical in larger sized lesions. Malignization can occur. The screening for endometriosis is mandatory by means of gynecologic, imaging and marked-tumor evaluation. We report a case of primary umbilical endometriosis and discuss its dermoscopic aspects.<br>A endometriose cut&#226;nea &#233; forma rara de endometriose, representando de 0,5% a 1% de todos os casos da doen&#231;a. Pode ser dividida em forma prim&#225;ria, de surgimento espont&#226;neo, ou secund&#225;ria, ap&#243;s procedimentos cir&#250;rgicos aonde geralmente encontra-se sobre a cicatriz cir&#250;rgica. Diversas etiologias foram propostas, por&#233;m, nenhuma capaz de explicar inteiramente seu aparecimento. Diagn&#243;sticos diferenciais incluem melanoma, n&#243;dulos metast&#225;ticos, quel&#243;ide e granuloma piog&#234;nico. A dermatoscopia da les&#227;o ainda n&#227;o foi bem estabelecida, mas existem alguns achados que podem sugerir o diagn&#243;stico. O tratamento &#233; cir&#250;rgico nos casos de les&#245;es maiores e o screening para endometriose &#233; mandat&#243;rio atrav&#233;s de avalia&#231;&#227;o ginecol&#243;gica, de imagem e marcador tumoral. Relatamos um caso de endometriose cut&#226;nea prim&#225;ria e discutimos seus aspectos dermatosc&#243;picos.
