Naevus lipomatosus superficialis is a rare lesion. It is regarded as a connective tissue naevus by most authorities. It can occur as either a single dermalpapule or as a cluster of multiple papules and nodules.
Histology of naevus lipomatosus superficialis
Sections of naevus lipomatosus superficialis show mature adipose tissue within the superficial and mid dermis (figure 1). There are frequently foci of fibrosis intermixed with the fat (figure 2).
