title: Noninclusion-body infantile digital fibromatosis: a lesion heralding terminal osseous dysplasia and pigmentary defects syndrome.
abstract: This report describes the histologic and immunohistochemical features of a peculiar type of digital fibroma that shares some clinical and microscopic features with the more common inclusion-body type infantile digital fibromatosis. However, this type does not exhibit inclusion bodies and its cells are reactive for vimentin but not for actin. Significantly, it presents in combination with a constellation of other clinical findings, i.e., mainly positional and bone abnormalities of the fingers and toes, and skin pigmentary defects. Thus, noninclusion-body digital fibromatosis may represent the first clue for the diagnosis of the so-called terminal osseous dysplasia and pigmentary defects syndrome.
