Abstract excerpt

We describe a case of fibrous hamartoma of infancy (FHI) with predominant pseudoangiomatous histologic pattern that harbors a recently described characteristic molecular feature of FHI: EGFR exon 20 insertion/duplication mutation. A left axillary mass of an 8-month-old male was biopsied. Microscopic findings revealed a CD34-positive spindle cell proliferation accompanied by slit like spaces within collagen,...
