| Summary: | Primary breast lymphoma is a rare malignant breast tumor, accounting for <1% of all breast
cancers. Among them, diffuse large B-cell lymphoma is the most common histologic subtype.
However, primary mucosa-associated lymphoid tissue (MALT) lymphoma is less common
and more indolent than diffuse large B-cell lymphoma, and primary MALT lymphoma of the
breast is extremely rare. We report a case of bilateral breast cancer in a 62-year-old woman
with primary MALT lymphoma in right braest and contralateral invasive breast cancer in left
breast. The patient presented with a palpable right breast lump, which appeared as a noncalcified
mass on mammography and an indistinct irregular hypoechoic mass with internal
vascularity on breast ultrasonography. The mass was pathologically confirmed by excisional
biopsy as primary MALT lymphoma. The patient underwent dynamic contrast-enhanced
breast MRI, which additionally detected a small suspicious mass in the left breast. This was
a clinically and mammographically occult breast cancer diagnosed as invasive ductal carcinoma. |
