The cause of dermatofibrosarcoma protuberans (DFSP) is unknown. Laboratory studies have shown that chromosomal aberrations may contribute to the pathogenesis of DFSP; however, no evidence of hereditary or familial predisposition exists. In 10-20% of patients with this tumor, trauma at the site seems to be incriminated.
Retinitis pigmentosa (RP) refers to a group of inherited diseases causing retinal degeneration. The cell-rich retina lines the back inside wall of the eye. The cells within the retina capture and process images which are then transmitted through the optic nerve to the brain. People with RP experience a gradual decline in their vision because retinal photoreceptor cells (rods and cones) die. Forms of RP and related diseases include Usher syndrome, Leberâs congenital amaurosis (LCA), rod-cone disease, Bardet-Biedl syndrome, and choroidermia, among others.
