It sounds like you’re probaably thinking of these:

…Near the base of the papilla [nipple], and upon the surface of the areola, are numerous large sebaceous glands, the areolar glands, which become much enlarged during lactation, and present the appearance of small tubercles beneath the skin. These glands secrete a peculiar fatty substance, which serves as a protection to the integument of the papilla during the act of sucking. – Anatomy of the Human Body (1918 ed.) by Henry Gray, The Mammæ
