Skull base chondrosarcomas represent 2% of all chondrosarcomas. They usually have a low grade of malignity and a complete resection may be curative. However, often they are considered irresectable because of the difficult approach and another kind of treatment is needed. We present a 54-year-old male case who, after weeks ...

Electronic medical record (EMR) systems have the potential to improve reporting of notifiable diseases beyond either traditional clinician-initiated or automated laboratory-based reporting systems. Traditional clinician-initiated passive surveillance is burdensome to clinicians and often incomplete and delayed. Electronic laboratory reporting addresses these limitations but often lacks information needed for public health ...

Nodular primary localized cutaneous amyloidosis (NPLCA) has been associated with progression to systemic amyloidosis. The reported estimate of 50% progression to systemic amyloidosis has come under scrutiny as recent studies have suggested a significantly lower rate. Still, it is essential to consider systemic amyloidosis after making the diagnosis of NPLCA ...

Hemangioblastomas are rarely found in a supratentorial location and are commonly associated with the von Hippel-Lindau complex. Therefore, patients with such tumors must be evaluated for both other hemangioblastomas within the central nervous system as well as for this complex via physical examination, radiographic examination, and genetic testing. We report ...
