Lipedema and Klinefelter Syndrome in Two Morbidly Obese Patients

Introduction: Lipedema is an abnormal deposit of subcutaneous fat most often involving the lower limbs symmetrically. The physiopathology is poorly understood, but its peak of the almost exclusively female involvement and its peak of appearance at puberty, during pregnancy or at menopause orient toward a hormonal involvement, whereas other elements are in favor of a strong genetic predisposition. Klinefelter syndrome (KS) is a genetic disease linked to aneuploidy resulting in a karyotype 47 XXY most of the time. There is a substantial variation in clinical presentation, but it often features infertility, firm testicular hypotrophy, hypergonadotropic hypogonadism, gynecomastia, and learning difficulties. Many other pathologies are associated with KS, but lipedema is never mentioned and there are no data in the literature linking these two pathologies.
