High-grade neuroepithelial tumor with medulloepithelioma-like areas out of the central nervous system in an infant with hemihypertrophy: a unique association

摘要

Case. The authors report on the first case of peripheral HNET associated with hemihypertrophy in an infant, with special discussion on histopathological differential diagnosis and management of this rare and highly malignant tumor. Conclusions. HNET should be included into the list of hemihypertrophy associated tumors. Complete surgical excision with free margins is essential for the successful treatment of such cases and should be tried in suitable cases at the time of diagnosis. Continued treatment should be decided individually on a case to case basis.
