Background/Purpose:
Bloody nipple discharge (BND) is rare, distressing for parents, and presents a challenge for physicians.
Methods:
We used PubMed to search for cases of BND that were diagnosed before adolescence and added data from two of our cases.
Results:
The analyzed cohort comprised 46 patients (28 boys and 18 girls; mean [SD] age, 12.5±13.3months; range, 20days to 4years). The mean time for spontaneous resolution was 2.8±2.4months (range, 1week to 8months) after onset of BND without any intervention. The diagnosis was mammary ductal ectasia (MDE) in 15 patients, gynecomastia with MDE in two patients, hemorrhagic cysts in two patients, and gynecomastia alone in one patient. The majority (89.3%) of patients <1year old were managed conservatively, but half of them aged >1year (50.0%) underwent surgery. Surgery was performed more often in patients in whom a mass had been identified.
Conclusions:
Age and findings at physical examination affect selection of treatment, but not sex. We found no reported cases of malignancy. Symptoms in children who are managed conservatively resolve within 10months. Children with BND should be conservatively managed to avoid the risk of developing breast deformities before adolescence.

Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
