Infantile myofibromatosis is a rare disorder characterized by the formation of tumors in the skin, soft tissues, bone, and viscera. We report the case of a 3-week-old girl who presented with severe hypertension due to generalized infantile myofibromatosis including renal involvement. The infant was treated by chemotherapy and showed progressive regression of the tumors. However, her evolution was marked by the development of aneurismal dilations of the renal and iliac arteries as observed in fibromuscular dysplasia. We discuss the possibility of a link between these two mesenchymal disorders.
A 9-year-old female with ataxia-telangiectasia (AT) presenting with papillary thyroid carcinoma and lymph nodes involvement is reported. We discuss this novel association, the general risk of neoplasic complications in these patients, the natural history of thyroid carcinoma in the pediatric population and the potential link between thyroid carcinogenesis and ataxia-telangiectasia mutated gene (ATM) mutation. We also expose our therapeutic attitude, according to both clinical status and particular genetic background of our patient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
