Multiple Recurrent Fibromatosis With Cranial Fasciitis Characteristics in a Pediatric Patient.

Cranial fasciitis is a rare, rapidly growing, but benign fibroblastic tumor of the skull that generally presents in childhood. Local resection or curettage of the affected bone is generally curative and the tumor is thought not to recur. Cranial fasciitis is distinguished by positive cytoplasmic and nuclear beta-catenin staining. Fibromatosis is a clonal myofibroblastic nonmalignant proliferation that generally demonstrates positive nuclear beta-catenin staining. In this report, the authors present a patient with fibromatosis with cranial fasciitis characteristics in a 2.5-month-old boy who has had 7 recurrences (total 8 resections) of this fibroblastic neoplasm over 6 years of follow-up.
