Abstract

The group of small round blue cell tumors of childhood represents a descriptive category of malignant pediatric neoplasms characterized by the presence of morphologically poorly differentiated cells containing large hyperchromatic nuclei and scant cytoplasm. Frequently, clinical and morphological clues can be identified, which may orient in the correct histopathological diagnosis of these tumors; in many occasions, however, the correct diagnosis will be accomplished only through the implementation of immunohistochemical, ultrastructural, and/or molecular analysis of neoplastic cells. Significant advances have been achieved in recent years, which have proved crucial in the diagnostic work up of these frequently challenging cases, as well as in providing markers of prognostic relevance and in uncovering potential therapeutic targets.
