Osteochondroma
Transient myeloproliferative disorder (transient leukemia)
Associated with trisomy 21 + scattered vesiculopustular lesions
Percentage of blasts in the bone marrow is lower than that of peripheral blood
Transient myeloproliferative disorder (transient leukemia) as opposed to acute megakaryoblastic leukemia
Features of NF1
Axillary/inguinal freckling, cafe au lait spots, Lisch nodules (iris hamartomas), neurofibromas, optic glioma, osseous lesion (sphenoid dysplasia or bowing of the long bone cortex w or w/o pseudoarthrosis)
Inheritance pattern of NF1
Autosomal dominant
Location of NF1 gene
Long arm of chromosome 17
