Adult-type Individuals presenting with<unk>  are usually adults thirty to fifty-five years old, often presenting with pain. Among adults,<unk> s develop equally in men and women. Infantile-type In infants,<unk>  (often termed congenital infantile<unk>  is usually congenital. Infants presenting with this<unk>  usually do so in the first two years of their life. Cytogenetically, congenital infantile<unk>  is characterized by the majority of cases having a translocation between chromosomes 12 and 15 (notated as t(12;15)(p13;q25)) that results in formation of the fusion gene, ETV6-NTRK3, plus individual cases exhibiting trisomy for chromosomes 8, 11, 17, or 20. The histology, association with the ETV6-NRTK3 fusion gene as well as certain chromosome trisomies, and the distribution of markers for cell type (i.e. cyclin D1 and Beta-catenin) within this tumor are similar to those found in the cellular form of mesoblastic nephroma. Indeed, mesoblastic nephroma and congenital infantile sarcoma appear to be the same disease with the exception that mesoblastic lymphoma originates in the kidney whereas congenital infantile sarcoma originates in non-renal tissues.
