This is a dermal melanocytic naevus with a few globules and remnants of brown pigment. Multiple comma vessels and terminal hairs are characteristic.

Main Menu

The diagnosis is highly suggestive of clear cell acanthoma because of the presence of dotted vessels distributed like a necklace of pearls or in a string-like pattern (see inset).

Main Menu

This is a cherry angioma with striking red lacunas. These are roundish, globular, sharply demarcated red structures.

Main Menu

This is a classic dermatofibroma with a delicate pigment network at the periphery and a central white scar-like patch. The central patch is described as scar-like because it is whiter than the surrounding skin.

Main Menu

This is a blue naevus characterised by a homogeneous pattern of structureless blue pigmentation. The history of a long lasting lesion with no change is typical.

Main Menu

This is a Spitz/Reed naevus typified by multiple streaks of pigmentation with globules arranged symmetrically at the periphery of the lesion in a radiating pattern (starburst).

Main Menu

This is a melanoma with a multicomponent pattern with polychromatism, an atypical pigment network with an abrupt cut-off at the periphery, a large blue-white structure in keeping with regression and dots/ small globules with peripheral streaks.

Main Menu

A dermal naevus with comma vessels, comedo-like openings and small brown globules at the periphery. These are typical features of a papillomatous dermal naevus (Unna type).

Main Menu

There are centrally located, thick and elongated linear vessels over a pink background corresponding to the thick invasive part of this melanoma. The presence of pigmented melanoma-specific criteria, namely irregular globules and streaks further facilitates the diagnosis.
