AbstractCongenital melanocytic nevus can mimic all the features of melanoma as size, morphological changes, inflammation, ulceration, regression, recurrence after excision.
The clinical features of the here reported congenital nevus simulate a melanoma of the nail matrix, in particular the Hutchinson sign - involvement of the lateral nail fold and hyponychium - and the pseudo-Hutchinson - involvement of the epinychium-.
In the nevi of children affecting the nail lamina also the dermoscopy signs can simulate melanoma, mainly the darker pigmentation, the pseudo-Hutchinson sign, the sign of the triangle - larger proximal part of melanonychia - and the presence of points and globules (2).
This is why the irregularities of the dermoscopic pattern according to some Authors (1) are not a valid discriminating criterion between nevus and melanoma in children (1).
