Breast lesions arising from IgG4-related diseases are rare and can be difficult to differentiate from breast cancer based on only imaging findings. A 46 year-old female was referred to our hospital complaining of swelling in her bilateral submandibular gland. Contrast-enhanced CT displayed the bilateral swelling of the submandibular gland, a pancreas mass, and a right breast mass. A needle biopsy of the breast showed a dense infiltration of lymphocytes and plasma cells with accompanying stromal fibrosis, as well as positive immunohistochemical reactions for IgG4 and increased IgG4 serum levels. These findings resulted in a diagnosis of IgG4-related disease, and oral steroid treatment was initiated. The breast tumor disappeared after 6 months. [ABSTRACT FROM AUTHOR]
