Peripheral stellate telangiectasias: a clinical-dermoscopic clue for diganosing cutaneous melanoma metastases.

BACKGROUND: The clinical and dermoscopic diagnosis of cutaneous melanoma metastases may be challenging especially in patients with unknown primary melanoma. MAIN OBSERVATIONS: We observed repetitive dermoscopic patterns of peripheral stellate telangiectasias in cutaneous melanoma metastases from 3 patients, of whom 2 had an unknown primary melanoma.
CONCLUSIONS: Stellate telangiectasias surrounding bluish to purple or red nodules with recent onset may represent a clue for cutaneous melanoma metastases.
