[Myerson nevus as a primary patch of Gibert pityriasis rosea. A case report].
There are only few articles in literature which discuss the association between Meyerson's naevi and Pityriasis rosea. And when so, the discussion is done in a controversial way. Here an 18 year old man is presented who visits the outpatient clinic. He has a ten day history of a solitary Meyerson's naevus on his back. Over the next three weeks this naevus will develop to the typical herold patch followed by the classical exantheme of Pityriasis rosea.


CONCLUSIONS
Halo dermatitis associated with Pityriasis rosea don't represent Meyerson's naevi. But they reflect the rare "nevocentric" property of a not so rare dermatose.
