Fibrous papule of the nose is a harmless small bump on or near the nose. It is typically dome-shaped, skin-colored, white or reddish, smooth and firm.[1] [2] Less frequently it can occur elsewhere on the face.[3] Sometimes there are a few.[1] It may be shiny and remains unchanged for life. There may be a central hair.[3]
The precise cause is unknown.[3] It is a type of angiofibroma which originates in a dendrocyte in skin.[4]
It is common, usually appearing in young adults and then remaining permanent.
Diagnosis is by visualisation, skin biopsy or histopathology of one that has been surgically cut out. Histopathology shows fibroblasts, fibrotic stroma, and large blood vessels. It can appear similar to a benign melanocytic naevus or an early BCC. It may be mistaken for a nevocytic nevus, neurofibroma, and pyogenic granuloma. The presence of several should alert to seeking for other signs of tuberous sclerosis.
Usually no treatment is necessary. Treatments for cosmetic reasons include shave excision and electrosurgery. Following treatment, recurrence is rare.
