Neglected, advanced breast cancer that has extended to the skin and infiltrated the underlying muscle.
Received is a left breast specimen measuring 17 x 9.5 x 3 cm, partially covered by an ellipse of skin measuring 14 x 7 cm. The nipple is not identified. An attached axillary tail measures 5.5 x 4 cm. Serial sectioning of the specimen reveals a solid, firm, creamy-colored mass measuring 5.5 x 5 x 2 cm. The mass is infiltrating the skin, located 1 cm from the deep margin, 3.5 cm from the superior margin, 1 cm from the inferior margin, and 2 cm from the medial margin, and 4 cm from the lateral margin. Dissection of the axillary tail yields 14 lymph nodes, the largest of which measures 3 cm in greatest dimension.
