The remnant may also evolve into a complete mammary gland resulting in the condition which is known as polymastia.

INTRODUCTION: Congenital anomalies of breast may present as Amastia (Absence of breast tissue) Athelia (Absence of the nipple), neonatal breast hypertrophy, polymastia (Accessory breast tissue) Polythelia (Supernumerary nipples), symmastia (Webbing between the breasts across the midline) Diffuse hypertrophy of the breast, and Tuberous breast (Breast is elongated from a narrow base to take a sausage-shaped contour, with a disproportionately large and protuberant areola and nipple).
Polymastia and accessory nipples are both not so common, seen in 2-6% of women.

Similarly, in the demosponge Polymastia
robusta, the choanocytes probably derive from larval flagellated cells, because the blastula larva of this sponge consists only of a layer of flagellated cells (Borojevic, 1967).
