Ossification rarely occurs within melanocytic naevi. As far as we know, mummification (presence of shadow cells) has never been described within these lesions. We report herein the case of a benign naevus associating ossification and mummification; this case suggests that, similarly to pilomatricomas, osteoma formation within melanocytic naevi may develop as a result of mummification.
