Biopolymer sarcoid-like foreign-body granulomas: Case report and literature review.

Iatrogenic allogenosis is a disease caused by the injection of biopolymers with esthetic purposes. Clinical manifestations can occur between six hours and 30 years after the procedure with local and/or systemic symptoms. The pathological findings are characterized by the presence of foreign body granulomas with a sarcoid-like reaction. Its interpretation is difficult given its association with sarcoidosis. We report the clinical case of a female patient with granulomatous lesions in reaction to a foreign body secondary to the multiple application of unknown substances on the face and buttocks.
