Abstract
Vaginal bleeding can occur shortly after delivery in 3%–5% of newborns as a consequence of placental hormone withdrawal . Although usually benign, its differential diagnosis includes central precocious puberty, tumours and other pathological conditions. A girl born at 26 weeks of gestation presented with five episodes of vaginal bleeding, each lasting less than a week, initiated at 4 months of age. Luteinising hormone and oestradiol levels were in the pubertal range. Later, she exhibited breast development, with no other pubertal signs. An ultrasonography test revealed an impregnated endometrium and a right ovarian cyst with 43 mm of diameter. A cranioencephalic MRI was unremarkable. Clinicians adopted expectant management and there was clinical, hormonal and radiological resolution in 3 months. The spontaneous resolution suggested mini-puberty of infancy. This is usually an asymptomatic condition, but to date, four cases of an exacerbated form in extremepremature infants have been reported. Long-term follow-up data are missing.
