A girl presents with, primary amenorrhea, grade V thelarche, grade II pubarche, no axillary hair, likely diagnosis is:
Tanner's Stage V thelarche means : 'Mature' breast development Stage II pubarche means : Sparse growth; We therefore have to look for a condition where development of breast is unaffected despite poor development of pubic hair. Thus, testicular feminization is the only condition out of these with well developed breast & poorly developed axillary hair or pubic hair.
