McGillicudy describes a pair of rudimentary abdominal mammae, and there is another similar case recorded.

Hartung mentions a woman of thirty who while suckling had a mamma on the left labium majus.

It was excised, and microscopic examination showed its structure to be that of a rudimentary nipple and mammary gland.

Leichtenstern cites a case of a mamma on the left shoulder nearly under the insertion of the deltoid, and Klob speaks of an acromial accessory mamma situated on the shoulder over the greatest prominence of the deltoid.
