RESUMO
Seven cases of recurring digital fibroma were seen over a 35-year period. All demonstrated the classical clinical, macroscopic, and microscopic features of this distinct tumour, including the pathognomonic round, eosinophilic cytoplasmic inclusion bodies. Ultrastructurally, all seven cases were confirmed to be myofibroblastic in nature, and the morphology and intracellular topography of the inclusion bodies suggested their derivation from contractile protein. These findings establish recurring digital fibroma as a neoplastic lesion of the myofibroblast.
