Abstract:
An intravenous pseudotumour at a traumatised site of the buccal mucosa of a 68-year-old woman is described. The lesion was composed of reactive spindle cell proliferation, merging of haphazard bizarre cells and inflammatory elements. Cellular morphology and immunohistochemical profile of proliferating cells reflected that of myofibroblasts. Conceivably, these cells may be derived from indigenous vascular smooth muscle cells. The present case represents a unique type of a reparative process intimately related to the tissue damage.
