Infantile myofibromatosis is the most common fibrous tumor of infancy, in which eighty percent of patients have solitary lesions with half of these occurring on the head and neck, and 60% are present at or soon after birth.:606 Less commonly, infantile myofibromatosis presents as multiple lesions of skin, muscle, and bone with about 1/3 of these cases also having lesions in their visceral organs. All of these cases have an excellent prognosis with their tumors sometimes regressing spontaneously except for those cases in which there is visceral involvement where the prognosis is poor. Infantile myofibromatosis and the classic form of mesoblastic nephroma have been suggested to be the same disease because of their very similar histology. However, studies on the distribution of cell-type markers (i.e. cyclin D1 and Beta-catenin) indicate that the two neoplasms likely have different cellular origins.
