    Microsurgical Resection of Glomus Jugulare Tumors With Facial Nerve Reconstruction: 3-Dimensional Operative Video.
    Oper Neurosurg (Hagerstown) 2018 May 8. Epub 2018 May 8.
    Hospital Universitário Evangélico de Curitiba, Department of Neurosurgery, Curitiba, Paraná Brazil.
    Paragangliomas are tumors originating from the paraganglionic system (autonomic nervous system), mostly found at the region around the jugular bulb, for which reason they are also termed glomus jugulare tumors (GJT). Although these lesions appear to be histologically benign, clinically they present with great morbidity, especially due to invasion of nearby structures such as the lower cranial nerves. These are challenging tumors, as they need complex approaches and great knowledge of the skull base. Read More

    Mohs micrographic surgery for nail unit tumors: an update and a critical review of the literature.
    J Eur Acad Dermatol Venereol 2018 Apr 28. Epub 2018 Apr 28.
    Dermatology, Department of Experimental, Diagnostic and Specialty Medicine, University of Bologna, Italy.
    Mohs micrographic surgery (MMS) is a good treatment option for epithelial neoplasms, especially when localized in areas where tissue conservation is crucial, such as the nail unit (NU). MMS is a method of radical excision offering high cure rates due to the margin control and functional preservation. Our aim is to provide a review on the use of MMS for the treatment of the most common nail tumors. Read More

    Long-term tumor control following stereotactic radiosurgery for jugular paraganglioma using 3D volumetric segmentation.
    J Neurosurg 2018 Apr 13:1-9. Epub 2018 Apr 13.
    Departments of 1 Otorhinolaryngology.
    OBJECTIVE The morbidity of gross-total resection of jugular paraganglioma (JP) is often unacceptable due to the potential for irreversible lower cranial neuropathy. Stereotactic radiosurgery (SRS) has been used at the authors' institution since 1990 for the treatment of JP and other benign intracranial tumors. Conventional means of assessing tumor progression using linear measurements or elliptical approximations are imprecise due to the irregular shape and insinuating growth pattern of JP. Read More

    A Distinct Malignant Epithelioid Neoplasm With GLI1 Gene Rearrangements, Frequent S100 Protein Expression, and Metastatic Potential: Expanding the Spectrum of Pathologic Entities With ACTB/MALAT1/PTCH1-GLI1 Fusions.
    Am J Surg Pathol 2018 Apr;42(4):553-560
    Department of Pathology & Laboratory Medicine, Mount Sinai Hospital, Toronto, ON, Canada.
    ACTB-GLI1 fusions have been reported as the pathognomonic genetic abnormality defining an unusual subset of actin-positive, perivascular myoid tumors, known as "pericytoma with the t(7;12) translocation." In addition, GLI1 oncogenic activation through a related MALAT1-GLI1 gene fusion has been recently reported in 2 unrelated gastric tumors, namely plexiform fibromyxoma and gastroblastoma. Triggered by unexpected targeted RNA-sequencing results detecting GLI1-related fusions in a group of malignant neoplasms with round to epithelioid morphology, and frequently strong S100 protein immunoreactivity, we investigated their clinicopathologic features in relation to other known pathologic entities sharing similar genetics.
