[Mammary hemangioma in an infant with apparent mastitis. Case report].

Mammary pathology is infrequent during childhood. It is rare the probability of finding a breast mass in an infant. The most frequent possible diagnoses at this age are breast abscess, mastitis, breast engorgement due to maternal hormonal stimulation and hemangioma. Reaching the proper diagnosis is essential in order to apply a suitable treatment and avoid the potential disease complications. We present the case of a female infant having a mass in the right breast from birth. Initially the entity was treated as mastitis. Nevertheless, the bad evolution made necessary considering the differential diagnosis. It was concluded to be a hemangioma. Due to the lesion ulceration and the potential risk of developing breast hypoplasia, treatment with propranolol was started. The tumor was almost completely resolved.
