Mucinous carcinoma of the breast accounts for about 2 % of invasive carcinoma and tends to occur in older women.
Clinical Features
Symptomatic tumors often present with soft palpable masses.
Mammographic Features
Mucinous lesions are round, oval, or lobular masses. They are usually well circumscribed, but may have indistinct or obscured margins. Calcifications are rare in pure mucinous cancers (Figs. 34.1a, b and 34.2a–c).
