Melanosis naeviformis of Becker (MNB) can be associated with hypoplasia of soft tissue or extremities, spina bifida and scoliosis of the vertebral column. We have investigated 50 patients (42 men, 8 women) with MNB radiologically. Scoliosis was diagnosed in 13 patients (26%). The curves of scoliosis varied from 11 degrees to 17 degrees. Physical examination revealed no gross asymmetries of the trunk, extremities or breasts. No correlation was seen between the age of patients and the scoliotic curve. In one family the father and oldest son had MNB with scoliosis and the other son and daughter had MNB without scoliosis. Since only mild scoliosis is found in patients with MNB, X-ray examination of the vertebral column has no therapeutic consequences.
