Café au lait spots:
Neurofibromatosis (VON RECKLINGHAUSEN'S DISEASE) 1 is characterized by cutaneous neurofibromas, pigmented lesions of the skin called cafe au lait spots, freckling in non-sun exposed areas such as the axilla, hamartomas of the iris termed Lisch nodules, and pseudoarthrosis of the tibia. Neurofibromas are benign peripheral nerve tumors composed of proliferating Schwann cells and fibroblasts. They present as multiple, palpable, rubbery, cutaneous tumors. They are generally asymptomatic; however, if they grow in an enclosed space, e.g., the intervertebral foramen, they may produce a compressive radiculopathy or neuropathy. Aqueductal stenosis with hydrocephalus, scoliosis, short stature, hypertension, epilepsy, and mental retardation may also occur.
