Primary breast lymphoma, contralateral breast cancer, and bilateral Brenner tumors of the ovary

Abstract

BACKGROUND: Primary lymphoma of the breast is an unusual clinical entity. Its presence with invasive breast cancer and bilateral Brenner tumors of the ovary is very rare. CASE: We report a 62-year-old woman referred for further evaluation of a palpable mass in her breast. She was diagnosed and treated for simultaneous primary lymphoma of the right breast, contralateral invasive ductal carcinoma, and bilateral Brenner tumors of the ovary. One year after treatment, she is free of recurrence or progression. CONCLUSION: Compared with breast carcinoma, primary breast lymphoma is a rare disease but should be considered in the differential diagnosis of breast masses. The presence of both breast malignancies presents a challenge in treatment decisions.
