INDEX OF SUSPICION
This section of Pediatrics in Review reminds clinicians of those conditions that can present in a misleading fashion and require suspicion for early diagnosis. Emphasis has been placed on conditions in which early diagnosis is important and that the general pediatrician might be expected to encounter, at least once in a while. The reader is encouraged to write possible diagnoses for each case before turning to the discussion, which is on the following page. We invite readers to contribute case presentations and discussions. Case 1 Presentation As you finish examining a 14-year, 11-month-old girl for an upper respiratory infection, she asks when she might expect to stop growing. When told that most girls stop growing after menarche, she explains that she has never had a menstrual period. On examination, her height is 69 1/2 in (above the 95th percentile) and her weight is 119 lb (50th percentile). Her breast development is at Tanner stage IV, and she says that her breasts have remained at their present state of development for at least 3 years. She lacks both pubic and axillary hair. Her external genitalia are normal, as is the remainder of her physical examination. Case 2 Presentation A 9-year-old girl is brought to your office having a 1-week history of bilateral neck swelling.
