In the course of life, the initially rather discrete splashes can transform into clearly defined black-brown papules, giving this nevus variant its typical aspect.
In rare cases, the development of malignant melanomas is observed in a nevus spilus. In this respect, the nevus spilus requires regular clinical monitoring.
Speckled lentiginous nevus syndrome is a cutaneous phenotype with nevus spilus (speckled lentiginous nevus) with hyperhidrosis, muscle weakness, dysesthesia or other neurological abnormalities.
Phacomatosis spilorosea (Happle 2005) is characterized by the combination of a naevus spilus with a naevus roseus, a capillary hamartoma, which was previously referred to as naevus flammeus lateralis.
Phacomatosis pigmentokeratotica (Happle 1996) is characterized by the combination of a nevus spilus with a nevus sebaceus.

Differential diagnosisThis section has been translated automatically.
The nevus spilus resembles the cafe-au-lait stain, but differs from it in the dark indentations in the underlying brown stain. The term "lapwing egg naevus "describes this aspect very well.
Becker ne vus: This nevus is not congenital, usually develops postpubertally (androgen dependence?) and shows hypertrichosis in addition to a broken reticulated border.
TherapyThis section has been translated automatically.
Annual inspection. Excise conspicuous, injected nevi early, as the danger of degeneration cannot be completely negated. If necessary, cosmetic cover with e.g. Dermacolor.

"spilus" = speckled
The lapwing is a bird whose eggs have a conspicuous mottle. The name is most likely derived from these.
