Hepatoblastoma presenting as precocious puberty: a case report

摘要

Hepatoblastoma (HB), a primary liver tumor in childhood, is often accompanied by alpha-fetoprotein (AFP) secretion, and sometimes by beta-human chorionic gonadotropin hormone (beta-hCG) secretion, and this can cause peripheral precocious puberty (PPP). We describe a case of PPP associated with HB. Laboratory tests showed an increase in AFP, beta-hCG and testosterone values, and suppression of follicle-stimulating hormone and luteinizing hormone levels. After chemotherapy and surgery, AFP, beta-hCG and testosterone levels normalized and signs of virilization did not progress further. The child did not show evidence for tumor recurrence after 16 months of follow-up. New therapeutic approaches and early diagnosis may ensure a better prognosis of virilizing HB, than reported in the past. Assessment of PPP should always take into account the possibility of a tumoral source.
