Primary lymphomas of the breast detected by Ga-67 scintigraphy.

Three patients with primary breast lymphoma were reported. All patients had rapidly growing breast masses and these masses showed nonspecific findings in mammography and on ultrasound. They resembled phyllodes tumor or invasive ductal carcinomas. Ga-67 scintigraphy showed intense accumulation was seen in all of the lymphomas. In one patient, a breast carcinoma was detected in the contralateral breast which did not show Ga-67 accumulation. In the other two patients, axillary involvement was also detected. Scintigraphy was helpful to confirm the diagnosis of breast lymphoma.
