Cutaneous horns usually appear on exposed skin areas in elderly men. The important issue in this condition is not the horn itself, which is just dead keratin, but rather the nature of the underlying disease, although the horns are usually benign.

Bone sarcoidosis of the skull is an infrequent presentation of sarcoidosis. We describe a 51-year-old man who consulted due to inflammatory-appearing nodulation in the right supraorbital region. Images showed a solitary osteolytic lesion extending to soft tissues with increased scintigraphic uptake. The anatomopathological study revealed the presence of non-caseating epithelioid granulomas, compatible with sarcoidosis. Steroid treatment led to a marked remission of the lesion, without evidence of relapse during a follow-up period of 1 year. The literature dealing with skull sarcoidosis is reviewed.
