Conservative management of gynecomastia in Peutz‐Jeghers syndrome: Case series and review of the literature

Abstract

AbstractPeutz‐Jeghers syndrome (PJS) is a childhood‐onset cancer predisposition syndrome that is associated with oral freckling and gastrointestinal polyposis. Male patients with PJS are at risk for large‐cell calcifying Sertoli cell tumors in childhood. These tumors are estrogen‐producing and can cause symptoms of precocious puberty, gynecomastia, and growth acceleration. Here we discuss our experience with spontaneous resolution or stabilization of breast enlargement without medical intervention in three patients with PJS and gynecomastia. These cases indicate that a watchful waiting approach can be considered in the management of gynecomastia in male children with PJS.
