Rare Tumors is the premier peer-reviewed international medical journal devoted entirely to the study, diagnosis, and treatment of rare cancers. The journal covers the diagnosis, classification, and treatment of rare tumors and hematological malignancies for physicians and medical scientists interested in uncommon neoplasms. The primary intent of the journal will be to publish clinically relevant information that will directly improve the care of patients with rare cancers. Basic science studies of interest to those treating rare malignancies will also be considered for publication when relevant. A special section of the journal is dedicated to Case Reports: we would like to invite clinicians and researchers to send us their reports.
