A case of bilateral mammary abscess in infant

Natsuko INAZAWA1) , Toshitaka KIZAWA1)

Mastitis is rare in infancy, and few studies have reported mastitis in infants aged<2 months. Moreover, unlike its presentation in adults, mastitis in infants is associatedwith abscess formation in >50% of cases, and early diagnosis and treatment are important. We report a case of mammary gland inflammation in a 4-month-old male infant who was admitted to our department with high-grade fever and erythema around the nipples bilaterally. On physical examination performed at the time of admission, a fingertip-sized mammary abscess was palpated under the nipples bilaterally. We performed prompt incision and drainage of the abscess, which healed well without any sequelae. A careful whole-body examination should be performed for evaluation of fever in infants, and clinicians should consider mastitis in the differential diagnosis to ensure prompt incision and drainage of the abscess.
