Blue Nevus (“cellular” blue nevus)

  • Guido Massi

The so called cellular blue nevus is a form of blue nevus which is composed of ovoid, pale, scarcely pigmented, non dendritic cells, while usually having at least a few dendritic, heavily pigmented melanocytes of the “common” form. These pale ovoid cells have a distinct inclination to aggregate in tightly packed round to oval nests. The term “cellular” reflects the high cellular density of the lesion. As noted in the section on common blue nevus, the dichotomy between “common” and cellular blue nevus is an oversimplification, but one that avoids the bewildering array of terms that more precise designations arise, as it somewhat correlate with clinical findings.
