Clinical information
Case 25 Female, 34 years. Punch biopsy from black spot, arisen in non-suspicious naevus, dorsum of foot
Show diagnosis & commentsDiagnosis:
Combined naevus
Comments:
The clinical information suggests that the blue naevus-component arose within the 'non-blue' banal compound naevus.
I have seen a number of very similar examples and have the impressing that the focal blue-naevus component of combined naevi may arise at some later stage than the rest of the naevus, manifesting itself clinically as a focus of increased pigmentation emerging in a previously stable naevus.
