Fig. 25.30 (A) Lobular hyperplasia showing numerous groups of acinar
cells having a uniform appearance (Papanicolaou x LP). (B) High-power
view showing lobular hyperplasia. A benign feature is the presence of
spindle shaped myoepithelial cells at the peripheral portion of the clusters
(Papanicolaou x HP).
