Montgomery’s Tubercles Definition

Montgomer's Tubercles.img

Montgomery’s tubercles are small, raised bumps that appear on the areola (the dark area around the nipple) during pregnancy. They are caused by an increase in the hormone levels and are perfectly normal. These bumps are sebaceous glands that help to lubricate the areola and keep it from cracking and irritation during breastfeeding. 

Montgomery’s tubercles typically disappear after pregnancy and breastfeeding has ended. However, some women may experience them permanently. There is no need for concern if you have Montgomery’s tubercles as they are benign (noncancerous). 

Montgomery’s tubercles are named after William F. Montgomery, an American obstetrician who first described them in 1837. 

Complications and Treatment

In some cases, Montgomery’s tubercles can become blocked, irritated and inflamed, causing redness and swelling. The pain can cause discomfort. If this occurs, Montgomery’s tubercles can be treated with a topical cream or ointment but a medical expert must be consulted.
