Dermatoses of the breast in lactation.

Dermatoses of the breast during lactation can be difficult to diagnose because of their overlapping clinical appearances. It is important to properly diagnose and treat nipple dermatitis since it can be a significant source of pain when nursing. Poorly controlled nipple pain in nursing mothers is one of the primary reasons for breastfeeding to be discontinued earlier than is recommended. Therefore, it is relevant for practicing dermatologists to be aware of certain facts in a patient's history, specific physical exam findings, and the most appropriate laboratory tests used to diagnose these conditions. In addition, the therapeutic approach should be effective and safe for the mother and infant. This review article provides dermatologists with a detailed discussion on the clinical features and management of various breast dermatoses seen in lactation, including atopic dermatitis, irritant contact dermatitis, allergic contact dermatitis, psoriasis, bacterial infections, yeast infections and herpes simplex virus infections.

Raynaud phenomenon of the nipple in breastfeeding mothers: an underdiagnosed cause of nipple pain.

OBJECTIVE: To elucidate the diagnostic criteria of Raynaud phenomenon of the nipple that will aid in recognizing and treating Raynaud phenomenon in breast feeding mothers with chronic deep nipple pain during lactation. DESIGN: Retrospective review of a patient database composed of 22 cases of breastfeeding mothers who fit the diagnostic criteria for Raynaud phenomenon of the nipple. SETTING: Menlo Dermatology Medical Group in Menlo Park, California, an academic-affiliated, private dermatologic referral center. PATIENTS: All patients diagnosed as having Raynaud phenomenon of the nipple evaluated from January 1, 2004,through December 31, 2010. MAIN OUTCOME MEASURES: The rate of failed treatment for Candida mastitis, the rate of improvement of symptoms with nifedipine use, and the overall rate of improvement of symptoms with appropriate therapy involving treatment of Raynaud phenomenon. RESULTS: Among the 22 patients with Raynaud phenomenon of the nipple, previous treatment for Candida mastitis with oral or topical antifungals was ineffective in 20(91%). Of the 12 patients who tolerated a trial of nifedipine,10 (83%) reported decreased or resolved nipple pain. All patients experienced marked improvement of symptoms with appropriate therapy involving treatment of Raynaud phenomenon. CONCLUSIONS: Most patients were treated with antifungals before presentation without resolution of nipple pain. Nifedipine appears to be an effective medication for the treatment of Raynaud phenomenon of the nipple. With appropriate management of Raynaud phenomenon,breastfeeding mothers demonstrated improvement of nipple pain. Raynaud phenomenon of the nipple should be considered in the differential diagnosis of nipple pain during lactation.
