A 15 year old female presents with primary amenorrhoea. Her breasts are Tanner 4 but she has no axillary or pubic hair. The most likely diagnosis is :: (A) Turner's syndrome, (B) Mullerian agensis, (C) Testicular feminization syndrome, (D) Premature ovarian failure
Answer is C. Answer is C (Testicular feminization syndrome): Presence of well developed breast (tanner stage 4) with scanty axillary or pubic hair in a phenotypic 'female' with primary amenorrhea (? no uterus) suggests the diagnosis of Testicular feminization syndrome.
