A 39-year-old woman consulted for an abdominal pigmented lesion.
Dermoscopy revealed exophytic papillary structures (*), clustered milia-like cysts (black circle), comedo-like openings (blue circle).
The wobble sign was present in favor of a Unna nevus.
The wobble sign is a useful sign when it is difficult to share between a Unna nevus and a seborrheic keratosis: the dermoscope put on the lesion is moved; if the lesion wobbles, it is a Unna nevus at the difference of a seborreic keratosis which does not wobble.
