[Fibrous papules of the nose--a clinical and histologic entity?].

Twelve patients with 19 fibrous papules of the nose were studied. Usually the papules appear domeshaped and are flesh colored or reddish-brown. The majority of the lesions are asymptomatic and firm, a few of them are soft. The microscopic changes of the fibrous papules of the nose were usually those of fibromas or angiofibromas with increased cellularity of the upper parts of the cutis. The cell shape varied greatly and included dendritic, stellated and strap-shaped forms as well as multinucleated giant cells, similar to those of juvenile melanomatas. It is considered that the fibrous papule of the nose is a special form of regressive nevus cells.
