The use of digital dermoscopy for the follow-up of congenital nevi: a pilot study.

One of the main problems in the management of congenital nevi is the potential risk for malignant transformation and the resulting need for follow-up examination. Dermoscopy is a noninvasive technique that has been shown to be useful for the follow-up of benign melanocytic skin lesions as well as the early diagnosis of malignant melanoma. Therefore we thought to use the digital dermoscopy (DD) technique for the follow-up of congenital nevi. For documentation purposes we registered an overview, and the following standardized dermoscopic images of every lesion: representative architectural pattern, border of the lesion, and regions of "special interest." In all instances the examination with digital dermoscopy was well tolerated by the patients and the integration of the parents to the "live" examination on the computer screen was appreciated. The follow-up was easy to perform with these standardized documents. We showed the feasibility of follow-up of congenital nevi using digital dermoscopy. Furthermore, we identified three different patterns as well as some typical structures seen in congenital nevi by DD.

Brain stem gliomas: a classification system based on magnetic resonance imaging.

MR scans of 87 pediatric patients with brain stem gliomas were retrospectively reviewed to develop a new classification scheme based on MR imaging. The scheme that has been developed utilizes primarily T2-weighted images, as these most accurately show tumor extent. Tumors are characterized as to location of origin, focality, direction and extent of tumor growth, degree of brain stem enlargement, degree of exophytic growth, and presence or absence of cysts, necrosis, hemorrhage, and hydrocephalus. The use of this classification allowed identification of differences in a population of patients who were selected to be as similar as possible. This system will aid in the assessment of new protocols for treatment of brain stem tumors.
