Background: Bullous impetigo is a superficial skininfection caused by Staphylococcus aureus (S.aureus). Pyogenic granuloma is a common benigntumor frequently associated with prior trauma.Bullous impetigo and pyogenic granuloma may occurin pregnant women.Purpose: The features of a pregnant womanwith pyogenic granuloma and bullous impetigoconcurrently present in a lesion on her finger aredescribed.Methods: PubMed was used to search the followingterms: bullous impetigo, pregnancy, and pyogenicgranuloma. All papers were reviewed; relevantarticles, along with their references, were evaluatedResults: A red ulcerated nodule with a collaretteof epithelium around the tumor and surroundingbullae appeared on the fifth digit of the left hand of a31-year-old woman who was at 36 weeks gestation. Abacterial culture grew methicillin sensitive S. aureus.An excisional biopsy was performed. Histologicfindings revealed not only a benign vascular tumorwith an infiltrate of mixed inflammatory cells, butalso an intraepidermal blister. She received oralantibiotics and there was complete resolution of thefinger lesion and infection with preservation of digitfunction.Conclusion: Albeit uncommon, pyogenic granulomaand bullous impetigo may concurrently occur in thesame lesion. Therapeutic intervention should focuson treating both the benign skin tumor and theinfection.
