			== Blue nevus ==

			===Microscopic description===
			The sections show a dermal lesion consisting of heavily pigmented epithelioid and spindle cells interspersed between collagen bundles. There is no nuclear atypia and the lesion does not extend into the superficial dermis. Lesional cells decrease in size and become more spindled with increasing depth. No mitotic activity is identified.

			Skin, posterior thorax, biopsy:
			Blue nevus, see comment.
