Surgical Treatment of Granulomatous Breast Deformities Caused by Injection of Foreign Substances in Transgender Women: A Case Series and Algorithm.

Summary: Despite potentially devastating complications, free foreign substance injections for feminizing breast augmentation remain common among transgender women. To date, the literature regarding surgical treatment of these deformities among transgender women remains limited. The authors present a case series of transgender women presenting for surgical management of granulomatous breast deformities secondary to free foreign substance injections between January of 2016 and February of 2020. Seven transgender women presented for surgical management of complications secondary to free foreign substance injections of the breast. These patients ranged in age from 29 to 53 years, all identified as Hispanic/Latinx, and five were primarily Spanish speakers. All were recipients of public insurance. Six of the seven patients received free foreign substance injections outside of the United States, with an average time from initial injections to presentation of 19.3 ± 15.7 years. Three patients presented with a history of prior revisions by other surgeons. Four underwent staged reconstruction at the authors' institutions. Patients were followed for, on average, 10.7 ± 12.6 months after their initial surgery. There were no major complications. The most common minor complication was delayed wound healing. In the present series, the authors illustrate that, with careful consideration and patient selection, it is possible to perform safe and successful breast reconstruction for the management of foreign substance granulomas in transgender women. They also provide an algorithm based on patient-specific factors to guide treatment decisions in this patient population. Further research is needed to determine the generalizability and applicability of this algorithm.
