The size of the h^pertrophy depends upon the number andvolume of these tumor formations. These spheroidal tumors vary in their composition. Most frequentlythey are fibro-myo-adenomata, but aU variations from an almostpure adenoma to pure myoma or fibroma are encountered. The puremyomata and fibromata are uncommon.

The tissue forming the periphery of thespheroids usually contains sparsely scattered acini which are com-pressed and elongated. Occasionally in the interspheroidal stroma 138 Hugh H.

At other times apartial condensation is noted.
