Calcifying epithelial odontogenic tumor (CEOT) is a rare neoplasm, which accounts for < 1% of all odontogenic tumors. CEOT occurs more frequently in adults with a peak incidence in the 5th decade of life and is extremely rare in the pediatric population. We present a case of a 13-year-old girl who was found to have a mandibular CEOT. We summarize the radiological features, pathological findings, clinical management and literature review focusing on this entity in children.Electronic supplementary materialThe online version of this article (10.1007/s12105-019-01009-1) contains supplementary material, which is available to authorized users.

Diagnostic testing that facilitates containment, surveillance, and treatment of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), or future respiratory viruses, depends on a sample collection device that efficiently collects nasopharyngeal tissue and that can be manufactured on site when an outbreak or public health emergency is declared by a government. Here two novel stereolithography‐based three‐dimensional (3D)‐printed nasopharyngeal swabs are reported which are made using a biocompatible and sterilizable photoresist. Such swabs are readily manufactured on‐site and on‐demand to ensure availability, if supply chain shortages emerge. Additionally, the 3D‐printed swabs easily adapt to current workflow and testing procedures in hospital clinical laboratories to allow for effortless scaling up of test kits. Finally, the 3D‐printed nasopharyngeal swabs demonstrate concordant SARS‐CoV‐2 testing results between the 3D‐printed swabs and the COPAN commercial swabs, and enable detection of SARS‐CoV‐2 in clinical samples obtained from autopsies.
