A case of multiple infantile fibromatosis of unclassified type

We report an unusual case of fibromatous disease in infancy, diagnosed as a multiple infantile fibromatosis of unclassified type. Histologically, the tumors are composed of a mixture of fibrous component and mature adipose tissue. The clinical manifestations resemble those of infantile myofibromatosis. The symptoms, including size and number of tumors, have not been progressive for one year.
