A 47-year-old woman was admitted on February 7, 1990 with numbness of the left side of her face that had been present for 2 months. This numbness extended from the forehead to the jaw in the distribution of the trigeminal nerve. In 1983 and 1984, the patient had undergone the removal of subcutaneous tumors of the right side of the neck, in both axillae, and along the right flank. The histologic...
von Recklinghausen neurofibromatosis (NF1) is the most common hereditary syndrome predisposing to neoplasia. NF1 is an autosomal dominant disease caused by a single gene which maps to chromosome 17q11.2. The most common symptomatic manifestation of NF1 is the benign neurofibroma. Our previous studies of tumors in NF1, studies which detected a loss of heterozygosity for DNA markers from the NF1 ...
For genetic linkage purposes, a subject at risk for Von Recklinghausen neurofibromatosis (VRNF) is one who has a first degree relative with independently documented VRNF. The presence of one or more of the designated criteria establishes the phenotypic diagnosis of VRNF in a subject at risk regardless of age. The absence of all of these criteria excludes the phenotypic diagnosis for all at risk...
A locus for von Recklinghausen neurofibromatosis (NF1) has recently been mapped near the chromosome 17 centromere. We have extended these linkage studies by genotyping 45 NF1 families with three DNA probes known to be linked to the chromosome 17 centromeric region. Of 34 families informative for NF1 and at least one of the three probes, 28 families show no recombinants with the disease gene. Th...
Neurofibroma, a benign peripheral nerve sheath tumor, usually appears together with café-au-lait spots, iris nodules, and other tumors within the scope of neurofibromatosis von Recklinghausen type 1 tumors. A solitary neurofibroma of the eyelid is relatively rare. In this case report, we present a 39-year-old woman who had a lesion on the eyelid crease, previously treated as a chalazion. Due to...
