INTRODUCTION: Isolated premature pubarche (PP) in infancy may be the reason for many diagnostic difficulties. This is due to the low incidence and, therefore, the limited number of studies on this subject and the lack of strict laboratory standards because of the physiological variability of gonadotropic hormone and androgen concentrations during minipuberty.
MATERIAL AND METHODS: We aimed to present current knowledge about PP in infancy based on the literature review and 2 cases of male infants with scrotal hair during minipuberty.
RESULTS: Isolated hair in the pubic region in a boy during the period of minipuberty requires differential diagnosis. After excluding serious aetiology, it seems to be a mild, self-limiting variant of precocious puberty. The phenomenon is probably a result of increased sensitivity of the hair follicles to transiently increased androgen concentration.
CONCLUSIONS: Isolated pubic hair in infancy as a mild, self-limiting variant of precocious puberty in infants should be a diagnosis of exclusion. The condition resolves spontaneously, but it absolutely requires further follow-up to exclude serious aetiology in the case of puberty progression.
