FIBROUS PAPULE OF NOSE - A CLINICOPATHOLOGICAL STUDY

[摘要] A clinicopatho-logical study of 40 patients with a distinct isolated fibrous papule of the nose is reported. The histogenesis and pathogenesis of the unique tumor indicates the lesion probably represents the residual of a cellular nevus in which stromal elements persist because of the anatomical location. There is a microscopic similarity of the fibrous papule to facial lesions of adenoma sebaceum and solitary hamartomas. For this reason the possibility that the lesion could represent a hamartoma or unusual type of neural end organ tumor can not definitely be ruled out. The name of fibrous papule is proposed for this benign dome-shaped tumor of the nose. Fibrous papule should be included in the differential diagnosis of lesions involving the nose, and particularly if the clinical characteristics are suggestive of a cellular nevus. Excision of the lesion flush with the surrounding skin is adequate treatment and allows for excellent cosmetic results.
