title: Hormone dust exposure a reversible cause of precocious pseudopuberty in siblings.
abstract: A seven year old female child presented with two episodes of vaginal bleeding and bilateral breast development. Examination showed normal anthropometric measurements and external genitalia of prepubertal type. Her 5-year old younger brother and her father had gynaecomastia. Search for a structural cause for precocious puberty was negative. Occupational exposure of her father to hormonal dust was identified as the cause. All pubertal changes reverted to normal after observing suitable precautions.
