A 57‐year‐old woman in good health presented with erythematous plaques that appeared first on the ankles (a, b) and then on the calves (e, f). Dermoscopy of the ankle plaques (c) showed whitish striae (asterisk) and red peripheral globules (arrow) consistent with lichen planus; those on the calves (g) showed translucent yellow–orange areas (asterisk) and branching linear vessels (arrows), suggesting necrobiosis lipoidica. Histology confirmed both diagnoses (d, h). Although we learned that all skin manifestations in one individual should be attributed to the same disease, the coincidental coexistence of different disorders can be observed. Dermoscopy could provide insight into peculiar features, avoiding superficial ‘at‐first‐glance’ diagnoses

Abstract
A 57‐year‐old woman in good health presented with erythematous plaques that appeared first on the ankles (a, b) and then on the calves (e, f). Dermoscopy of the ankle plaques (c) showed whitish striae (asterisk) and red peripheral globules (arrow) consistent with lichen planus; those on the calves (g) showed translucent yellow–orange areas (asterisk) and branching linear vessels (arrows), suggesting necrobiosis lipoidica. Histology confirmed both diagnoses (d, h). Although we learned that all skin manifestations in one individual should be attributed to the same disease, the coincidental coexistence of different disorders can be observed. Dermoscopy could provide insight into peculiar features, avoiding superficial ‘at‐first‐glance’ diagnosesI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
