Breast abscesses in Nigeria: lactational versus non-lactational.

This review of 299 cases of breast abscesses seen over a 10-year period (1981-1990) at the University of Calabar Teaching Hospital in Nigeria seeks to establish the current status of breast abscesses in the tropics. Lactational breast abscess constitutes 95% of breast abscesses while non-lactational breast abscess constitutes only 5% in this review. The commonest pathogen cultured from lactational breast abscess is Staphylococcus aureus and the disease responds to incision and drainage and systemic antibiotics, while non-lactational breast abscess is caused mostly by anaerobic organisms, usually with underlying mammary duct ectasia. The low incidence of non-lactational breast abscess corresponds to the low incidence of cigarette smoking and mammary duct ectasia in Nigerian women. While the high incidence of lactational breast abscess corresponds to the high rate of breast feeding and low level of personal hygiene in the low income group Nigerian women in which the disease is commonest. Economic recession has also reduced patronage of artificial feeds thus intensifying breast feeding and consequent lactational breast abscess.
