Bloody discharge from the nipple (thelorrhagia) is a rare symptom in childhood and is a cause of great concern due to the mistaken association with carcinoma in adults. However, in children thelorrhagia is due to benign mammary duct ectasia in the majority of cases. Up to date, only isolated case reports or case series have been published and, although different theories have been postulated, no definite etiology has been identified. We report two cases with similar clinical features and outcome, in whom bleeding resolved spontaneously 4 and 6 weeks after onset. We present a review of the literature. Based on the benign and self-limiting process and in the absence of other findings on physical examination, we suggest a watch-and-wait approach with minimally invasive studies and reassurance and support for the family as most cases resolve spontaneously.
