Infantile myofibromatosis, congenital fibrosarcoma and congenital/infantile haemangiopericytoma are generally considered distinct entities. Overlapping microscopic features between infantile myofibromatosis and congenital fibrosarcoma, and between infantile myofibromatosis and congenital/infantile haemangiopericytoma, however, have been noted, but not formally reported. This report concerns six neonatal tumours, each exhibiting more than one of the above patterns, supporting a histogenetic relationship among these entities. Immunohistochemistry for smooth muscle actin was found to be useful in the diagnosis of congenital/infantile haemangiopericytoma, and also served to support a histogenetic relationship with the other two entities under consideration.
