BREAST CYTOPATHOLOGY

Gynecomastia 49
Figure 2.33. Gynecomastia. An atypical ductal epithelial fragment
with large crowded nuclei. A total lack of individually dispersed
epithelial cells helps to rule out carcinoma in these cases. (Smear,
Papanicolaou.)
Figure 2.34. Gynecomastia. Higher magnification of a ductal epithelial
fragment shows enlarged crowded nuclei with occasional
myoepithelial cells. One should have a much higher threshold for
an atypical/cancer diagnosis in a male breast aspiration because of
the significant cytologic atypia in these lesions and the rarity of male
breast carcinoma. (Smear, Papanicolaou.)
