 Abstract

Klinefelter syndrome (KS) is one of the most common congenital chromosomal abnormalities and one of the most common causes of infertility in men. As there are mosaic forms (eg. 47,XXY/46,XY; 47,XXY/46,XX), there are also non-mosaic forms (eg. 47,XXY; 48,XXY; 49,XXXXY; 48,XXYY) of the disease. Although the clinical findings are variable, the mosaic forms have milder phenotype than non-mosaic forms. In addition to common features, some rare findings such as Persistent Mullerian Duct Syndrome, micropenis, cryptorchidism, and hypospadias may accompany the disease. We report here a 27-year-old male 47,XXY/46,XY (80%/20% respectively) mosaic type KS patient with unusual abnormalities like scrotal hyperpigmentation and evident intellectual disability as well as known ones and discuss it in the context of the literature.


Key words: Klinefelter syndrome, mosaicism, persistent mullerian duct syndrome, scrotal hyperpigmentation
