[A rare cause of gynecomastia in a more than 70-year-old man. Case report and differential diagnostic considerations]. / Seltene Ursache einer Gynäkomastie eines über 70jährigen Mannes. Kasuistik und differentialdiagnostische Uberlegungen.

Gynecomastia in elderly men is relatively common and may be caused by age-related endocrinal and metabolic disorders, the use of certain drugs, or specific medical conditions. We report here on the rare case of a 77-year-old man in whom gynecomastia was one of the major symptoms of a bronchial carcinoma which had metastasized to the mediastinum. The differential diagnosis of the condition is described in detail.
