    Ann Transplant 2017 Jan 31;22:53-57. Epub 2017 Jan 31.
    Department of Oncological and Reconstructive Surgery, Cancer Center, Institute of Maria Skłodowska-Curie in Gliwice, Gliwice, Poland.
    BACKGROUND The human face is a one-of-a-kind structure with unique morphology, complexity, and function, in which different subunits are not even similar to other parts of the body. Therefore, extended complex deficits of the face are usually difficult to reconstruct, and autologous tissue restoration is generally not able to give a satisfactory aesthetic and functional outcome. The main goal of face allotransplantation is to restore symmetry, contour, and appearance as well as function of the face, especially control of orbicularis oculi and oris muscle physiology.

    Annu Rev Pathol 2017 Jan;12:53-74
    Department of Neurology, Washington University School of Medicine, St. Louis, Missouri 63110; email:
    Neurofibromatosis type 1 (NF1) is a common neurogenetic disorder in which affected children and adults are predisposed to the development of benign and malignant nervous system tumors. Caused by a germline mutation in the NF1 tumor suppressor gene, individuals with NF1 are prone to optic gliomas, malignant gliomas, neurofibromas, and malignant peripheral nerve sheath tumors, as well as behavioral, cognitive, motor, bone, cardiac, and pigmentary abnormalities. Although NF1 is a classic monogenic syndrome, the clinical features of the disorder and their impact on patient morbidity are variable, even within individuals who bear the same germline NF1 gene mutation.
