THU202 Peripheral Precocious Puberty In A 7-year-old Female As A Result Of Exposure To Bath Bombs

Disclosure: C.C. Gordner: None. Introduction: Recent studies have demonstrated a progressive decrease in the age of onset of puberty in children. Endocrine disrupters are increasingly being identified as an important contributing factor to this shift in pubertal timing. We present here a case of peripheral precocious puberty in a 7-year-old female after a brief intense exposure to bath bombs. Clinical Case: A healthy pre-pubertal 7-year-old female used daily bath bombs for 7 days. She developed tender Tanner II breast buds the following week with no other pubertal or adrenarchal signs. Growth chart review revealed stable linear growth without growth acceleration. Bone age x-ray was consistent with chronologic age (CA 7y0m, BA 6y10m). LH, ECL, was 0.058 miU/mL (ref: 0.02-0.3), Estradiol, LCMS, was 2.0 pg/mL (ref < 15), DHEA-Sulfate, LCMS, was 45 mcg/dL (ref: 6-7y: < 72). The breast buds started to resolve after 2 months and were completely gone after 3 months from the initial exposure. Clinical Lessons: Endocrine-disrupting chemicals are found in pesticides, plasticizers, lavender, fennel, and tea tree oils and can lead to precocious puberty, delayed puberty, and/or impact sexual differentiation. Consumer products are often not well labeled to identify these chemicals and often use confusing terminology like “all-natural” and “organic” which can be misleading. Conclusions: Bath bombs should now be added to the growing list of consumer products associated with precocious puberty. Leaders should advocate for better labeling of consumer products to help identify potentially harmful products. Presentation: Thursday, June 15, 2023
