Management of prepubertal gynecomastia in two monozygotic twins with Peutz-Jeghers syndrome: from aromatase inhibitors to subcutaneous mastectomy.

Abstract

BACKGROUND:

Prepubertal gynecomastia is characterized by the presence of palpable uni- or bilateral breast tissue in boys without other signs of sexual maturation. It may be the endocrine expression of rare syndromes such as Peutz-Jeghers syndrome (PJS). This study aimed to evaluate the effectiveness of anastrozole and to describe an innovative surgical approach.

METHODS:

This report presents twins with PJS, bilateral prepubertal gynecomastia, and testicular multifocal calcifications. Both twins were treated with anastrozole for 2 years. After finishing treatment, both were followed before subcutaneous mastectomy was performed by the "modified" Webster technique.

RESULTS:

Growth velocity decreased and gynecomastia diminished during anastrozole treatment. After discontinuation of therapy due to a sharp reduction in growth velocity, both twins showed regrowth of gynecomastia, with painful and strained breasts. A significant reduction in breast volume with glandular removal was achieved.

CONCLUSIONS:

The findings of this study showed a multidisciplinary approach to prepubertal gynecomastia due to the synergy of pediatricians, radiologists, and plastic surgeons. The follow-up evaluation after the anastrozole treatment showed it to be an efficacious medical treatment, as an alternative to orchidectomy, to control the effects of circulating estrogens. Moreover, the results observed in the patients confirmed the validity and feasibility of the "modified" Webster technique in terms of aesthetic and functional results, patient satisfaction, and absence of complications.
