Squamous cell carcinoma

A 74-year-old man consulted for a scalp tumor.


Dermoscopy revealed an unspecific whitish pattern with a scaly and crusted surface. A biopsy was performed and pathology was in favor of a squamous cell carcinoma (SCC).
Usually, the dermoscopic features of SCC are an unspecific pattern with scales and polymorphous blood vessels typically surrounded by a whitish halo.

Squamous cell carcinoma

A 70-year-old man consulted for a keratotic tumour on his scalp.


Dermoscopy revealed an unspecific pattern, with many polymorphous vessels.
Polymorphous vessels were the only dermoscopic sign in favor of a malignant tumour.
Clinical and dermoscopic features were in favour of squamous cell carcinoma. A biopsy was performed and pathology confirmed this hypothesis.

Squamous cell carcinoma

A 78-year-old man consulted for this rapidly enlarging tumor on the left side of his nose. The lesion was present for 3 months. The possible clinical diagnoses were keratoacanthoma, squamous cell carcinoma, and basal cell carcinoma.
Dermoscopy revealed whitish halo (A) and linear-irregular vessels (B). The lesion was excised and pathology was in favor of a squamous cell carcinoma.
