A 48-year-old woman with no relevant previous history presented with a right breast mass. A simple mastectomy was performed. Grossly, a 5.0 x 4.8 x 4.0 cm mass well circumscribed mass was present in the retro-areolar region at the junction of the upper outer and inner quadrants. The mass had a tan, homogenous cut surface with “cleft-like” areas grossly visible. Focal gelatinous areas were also seen within the mass. A capsule is identified, but focal areas showed extension of the mass through the capsule into the peri-lesional breast parenchyma. A few satellite nodules were also present in the rest of the breast parenchyma, which appeared to be discrete (non-contiguous) from the larger mass.
