Introduction: 45,X/46,XY mosaicism is rare difference/disorder of sex development(DSD) with an incidence of 1.7 per 10,000 newborns. Children with this type of DSD have varying phenotype of internal and external genitalia/ gonads, Turner-like features and increased risk of gonadal malignancy posing great clinical challenge.Case presentation: A 13-year-old girl was referred for primary amenorrhea. She had been investigate...
