Concurrent pyogenic granuloma and bullous impetigo of a pregnant woman's finger.
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.


OBJECTIVE
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.


CONCLUSIONS
Albeit uncommon, pyogenic granulomaand bullous impetigo may concurrently occur in thesame lesion. Therapeutic intervention should focuson treating both the benign skin tumor and theinfection.
