Raynaud's Phenomenon of the Nipple: A Case Report of Postpartum Recurrence and Treatment.

Raynaud phenomenon is a well-known condition that is characterized by episodic vasoconstriction of the extremities leading to pain and discoloration. It is more common among women than men and often results from exposure to cold or stress. Raynaud phenomenon can also affect the nipple during breastfeeding, causing severe pain and distress for the lactating individual and newborn, leading to premature cessation of breastfeeding. Raynaud phenomenon of the nipple is often confused with other breastfeeding pain causes, which can result in treatment oversights. The etiology of Raynaud phenomenon of the nipple is complex and thought to be caused by an interplay of hormones and stress in the peripartum period. Literature on this condition is limited, mostly consisting of case reports, and there are very little data about its recurrence in subsequent peripartum periods. Treatment options are similar to those for Raynaud phenomenon and, if initiated in a timely fashion, can allow breastfeeding to continue uninterrupted. This clinical rounds article presents a case report of Raynaud phenomenon of the nipple after a first birth and a reoccurrence during a subsequent (second) postpartum period. Discussion of the pathophysiology, clinical presentation, diagnostic tips, and appropriate treatment options are included.
