Streptococcus sanguinis isolated from filler granuloma: Successful treatment with incision and drainage.

Filler granuloma is considered to be the result of delayed immune responses; growing evidence suggests that they may be secondary to biofilm formation. Dermal filler is technically a foreign body, and as the development of newer generations of dermal fillers lengthens their duration, it is possible that there is also an increased risk of biofilm formation. Here, we present a case report of a patient with Streptococcus sanguinis isolated from a filler granuloma, suggestive of biofilm formation. This case demonstrates the effective use of antibiotics after incision and drainage on antibiotic resistant biofilm.
