HEMORRHAGE IN PREPUBERTY (Part One)
General
Menarche (the first cycle) occurs when the breast has reached development in Tanner stage III or IV. Normally, menarche occurs at the age of 11-14 years. The normal cycle lasts up to 7 days or less, with a quantity of up to 80ml or less, and with a frequency of 21-45 days.
The menstrual cycle occurs when there is a coordinated function of the Hypothalamic - Pituitary - Ovarian axis. The first menstrual cycles are irregular as a result of incomplete maturation of this axis.
95% of hemorrhages in adolescence occur from anovulation. Of these, 55-82% occur within the first 2 years and 20% of them occur in the first 4-5 years.
Any type of hemorrhage that occurs without breast development should be evaluated for some other possible cause.
Causes of prepubertal hemorrhage
The causes of prepubertal hemorrhage are diverse, therefore it is necessary to take a careful history and a complete physical examination in order to determine the exact cause, so that appropriate treatment can be undertaken.
1 - Vulvar or external
- Skin conditions (lichen sclerosus, lichen simplex chronicus, lichen planus, psoriasis, eczema)
- Pigmented lesions
- Tumors and cysts
