Aspergillus colonization associated with bilateral silicone mammary implants.

A case of Aspergillus niger fungal colonization associated with bilateral inflatable silicone mammary implants is reported. Painful fibrous capsular contractures without clinical evidence of infection or inflammation characterized the presenting symptoms. Operative findings included a cheesy-white exudate that surrounded the implants and turbid fluid within the implants. All specimens yielded a heavy growth of Aspergillus niger. Special stains of the fibrous capsules were negative for fungal invasion. The etiology and pathogenesis of Aspergillus colonization in this patient are postulated.
