We compared the frequency of ovarian microcysts in girls with premature thelarche (n = 27) to that in age-matched control subjects (n = 24). There was an increased prevalence of detectable ovarian microcysts in girls with premature thelarche. The presence or absence of cysts did not correlate with basal gonadotropin or estradiol levels.

Case ReportsAcute mercury poisoning (acrodynia) mimicking pheochromocytoma in an adolescent.
A 14-year-old boy was seen because of irritability, insomnia, lethargy, and profuse sweating, together with hypertension (blood pressure: 160/120 mm Hg), tachycardia, and a diffuse erythematous rash with desquamation of the palms and soles. Initial biochemical investigation suggested a diagnosis of pheochromocytoma, but subsequently a history of exposure to mercury vapor was obtained. This case emphasizes the clinical and biochemical similarities between mercury poisoning (acrodynia) and pheochromocytoma.
