A 73-year old woman consulted for this ulcerated tumor of her forehead. The main clinical diagnosis was a basal cell carcinoma.
Dermoscopy confirmed easily the diagnosis, showing ulceration and many blue ovoïd nests.
Blue ovoïd nests (or blue-gray ovoïd nests) are well circumscribed areas, larger than blue-gray globules and often associate. Their presence is a good dermoscopic sign for a basal cell carcinoma.
