Melanoma, malignant, nodular: in the centre of the lesion of red surface smooth nodules with peripheral growth, here formation of small clots which are no longer distally connected to the primary tumour (satelliteosis).

Keratoakanthomas, multiple eruptive. suddenly formed, now 1.0 cm in diameter, hard, painless, bowl-shaped node with marginal lip and central horn plug (typical morphology). sliding on the pad. no regional lymph node swelling. in the surrounding area beside single actinic keratoses, several skin-coloured or slightly yellowish solid papules up to 0.4 cm in size (initial keratoakanthomas). 73-year-old patient with long-term immunosuppression (!).

Condylomata gigantea:tumour-shaped or cauliflower-like nodes growing exophytically and locally infiltrating in the anal region

Melanoma, malignant, nodular, solitary, solid, sharply defined, surface smooth, non-hairy, black speckled, symptomless lump, growing for more than a year, foundduring routine examination (lump has always been there). Incident light microscopy revealed strong grey-blue streaks and massive pigment network break-ups.
