Fatty degeneration of mammary glands in female-to-male transsexuals

Abstract

Background

Subcutaneous mastectomy is an accepted procedure for surgical reassignment in female-to-male (FtM) transsexuals. However, fatty degeneration of the mammary gland (FDMG) is sometimes observed in FtM transsexuals, with implications for mastectomy outcomes. In this study, we describe the characteristics and risk factors of FDMG.

Methods

A total of 48 FtM transsexual patients underwent bilateral subcutaneous mastectomies (96 subcutaneous mastectomies) at our clinics from January 2015 to February 2016. The patients were divided into FDMG and non-FDMG groups after evaluation of the cut surface of the resected mammary gland. The groups were compared in terms of age, smoking, hormonal therapy (testosterone), body mass index (BMI), breast size (top–under perimeter), distance between sternal notch and nipple–areolar complex (NAC), breast ptosis grade, weight of resected breast tissue, and complication rate. FDMG tissue specimens were examined histologically.

Results

Comparing the FDMG and non-FDMG groups, hormonal therapy was more common (91.3 vs. 72.0%, p = 0.049), BMI was higher (24.3 vs. 21.1%, p < 0.001), and distance between the sternal notch and NAC was longer (20.5 vs. 18.8%, p = 0.03).

Conclusions

Hormonal therapy, high BMI, and long distance from the sternal notch to the NAC are risk factors for FDMG and should be considered prior to mastectomy in FtM transsexuals.

Level of Evidence: Level III, risk/prognostic study
