Ocular adnexal lymphoproliferative lesions consist of a spectrum of disease entities, including reactive lymphoid hyperplasia, atypical lymphoid hyperplasia, and lymphoma. No clinical or radiologic criteria facilitate a distinction among these lymphoproliferative lesions. The two hyperplastic processes may evolve to localized or systemic lymphoma. ⋯ In comparison, intermediate- and high-grade lymphomas are less common in the ocular adnexa but more aggressive. An approach to the diagnosis and treatment of these complex entities is suggested. Despite new pathologic classification schemes, immunophenotypic labeling, and molecular genetic analysis, the prognosis for patients with small-cell lymphoma in the ocular adnexa is difficult to predict.

During the past several decades, the transport of critically ill patients to and between hospitals has gradually improved. The major indications that necessitate emergency transport for adult patients are trauma and acute cardiac disease, and the establishment of transport teams trained in the care of these conditions has improved the outcome of adult patients. ⋯ Such a program emphasizes stabilization of the child's condition at the local hospital, followed by transport to a pediatric intensive-care facility by a specially trained pediatric transport team. In this review, we present an overview of the principles and operating procedures of such pediatric transport teams.
