Basically, the multicomponent pattern is nothing but a combination of three or more distinctive dermoscopic structures within a given lesion. For instance, a multicomponent pattern may be made up of zones of pigment network, clusters of dots/globules, and areas of diffuse hyper- or hypopigmentation to name a common example.

Diagnostic significance

The multicomponent pattern is highly suggestive of melanoma, but may be also frequently found in basal-cell carcinoma. Multicomponent patterns are rarely observed in acquired and congenital nevi or in other non-melanocytic lesions, such as seborrheic keratoses or angiokeratomas.
