Dermoscopy quiz (3 of 3)

Invasive melanoma, Breslow depth 0.76 mm.

The clinical picture is of a 6 mm diameter, slightly irregular, tan brown lesion with a slightly dry surface. Dermoscopy is non-specific. The characteristic features of seborrhoeic keratosis and pigmented basal cell carcinoma are absent, so it must be considered a melanocytic lesion. There is no pigment network, but there are irregular amorphous areas. There is a cluster of brown dots at 9 o'clock and solitary large globules at 2 and 4 o'clock.
