Complications Following BellaGen™ Injection.

BellaGen™ is an injectable acellular dermal matrix granule derived from donated human skin tissue that was recently developed for soft tissue augmentation. Its use has been sporadically reported in penile girth enhancement procedures. Many cases of complications have been reported after injecting acellular dermal matrices like AlloDerm or SureDerm™ but few reports on complications associated with BellaGen™ injection. We report here on penile skin inflammation and necrosis following augmentation phalloplasty with BellaGen™, which developed 3 days after the injection and persisted for more than 2 weeks. The patient had a 15 year history of type 2 diabetes mellitus, and he was treated with oral antibiotics and wet dressings with KMNO4 solution to combine preservation of the remaining penile soft tissue with debridement of avascular tissue. The lesion improved with this treatment, but the patient experienced pain for about 2 weeks. All patients should be informed of the potential complications with the use of injectable acellular dermal matrices before treatment. Patient selection for augmentation is also important to have the most desirable results.
