A 36-year-old Caucasian primigravida presented at38 weeks gestation after spontaneously developing six vio-laceous pedunculated tumours located on the right armand left back 7 weeks prior. Each tumour was noted to bewithin irregular violaceous patches present since birth,previously diagnosed as port wine stains. The pregnancywas complicated by gestational diabetes mellitus, hyper-tension and mild pre-eclampsia. Two weeks after parturi-tion the tumours had slightly decreased in size but werestill symptomatic and so were removed with shave exci-sion and electrodessication. Histopathology revealed lobu-lated capillaries with plump endothelial cells lined bysquamous epithelium, some with ulceration, consistentwith pyogenic granulomas.
Reports of single pyogenic granuloma arising sponta-neously within a capillary vascular malformation duringpregnancy and multiple after laser treatment exist. To ourknowledge, this is the first case of multiple pyogenic gran-ulomas arising spontaneously within multiple port winestains during pregnancy without prior laser treatment.
